Yeastar S100 Linkus Cloud Service Annual Renewal in Dubai, UAE
A one-year renewal for existing Yeastar S100 environments that use Linkus Cloud Service to support remote Linkus client connectivity while the S100 remains the on-premises PBX.
This renewal is most relevant when a business intends to keep its S100 in service and wants continuity for Linkus users. FourTeck can help confirm the PBX model, serial number, current subscription situation, renewal requirement, and whether the standard LCS service still matches the intended remote-working workflow.

What This S100 Linkus Renewal Actually Does
The S100 LCS annual renewal continues a cloud-assisted connection service for Linkus users on an existing Yeastar S-Series PBX. It is not a replacement PBX, not a migration to a hosted PBX, and not a license that changes the hardware capacity of the S100. The practical purpose is to keep the remote Linkus experience available for users who need their business extension and supported unified communication functions away from the local office network.
That distinction matters to procurement teams. An organization may already own an S100 with working extensions, trunks, call routing, IVR, voicemail, queues, recordings, and desk phones. Its immediate requirement may simply be to extend the Linkus service term because staff still work from home, travel between client sites, supervise multiple locations, or use smartphones and computers as business extensions. In that situation, replacing the entire communication platform only to maintain remote user access may be unnecessary in the short term. A correctly processed renewal can be a practical continuity decision while the company evaluates its longer-term telephony roadmap.
Yeastar designed Linkus Cloud Service for its on-premises S-Series PBX family. The service uses a tunneling approach for Linkus communication and is separate from Yeastar Cloud PBX. For an S100 owner, this means the PBX remains physically deployed at the business location while the Linkus service assists supported remote client connectivity. This architecture can suit companies that want to retain their established on-premises call routing and telephony interfaces while giving selected users more flexible access.
There is also a lifecycle factor that should not be ignored. Yeastar lists the S100 as end-of-sale from July 1, 2022 and identifies the P560 as a recommended migration path. Existing S100 systems can still represent useful installed infrastructure, but renewal decisions should be made with awareness that the platform is no longer a current-sale appliance. A business that expects major user growth, new integrations, a broad remote SIP requirement, or a multi-year modernization project should compare the cost and operational value of renewal against a planned move to a current Yeastar platform.
FourTeck helps UAE buyers treat the renewal as a compatibility and continuity decision rather than a generic software purchase. Before a quotation is finalized, it is useful to confirm the exact S100 model, PBX serial number, existing Linkus service type, expected renewal term, remote-user requirement, and any planned system changes. Those details reduce the risk of ordering the wrong service or renewing a legacy arrangement that no longer matches the way the business needs to communicate.
Key Business Benefits of Renewing LCS for S100
For an organization that intends to keep its S100 in service, the main value of renewal is continuity: users can maintain the remote Linkus workflow they already understand without treating the subscription as a new PBX deployment.
Keep Remote Linkus Workflows Running
If employees already depend on Linkus for business extension access outside the office, an annual renewal can prevent an avoidable change in daily workflow. Sales staff can remain reachable on business numbers, managers can continue using extension features while traveling, and remote employees can retain a familiar communication client. The value is not merely technical; it reduces disruption in teams that have built routines around their PBX extension, presence, contacts, messaging, voicemail access, and call handling through Linkus.
Retain the On-Premises PBX
Linkus Cloud Service does not turn the S100 into a cloud PBX. The organization keeps its established on-site call-routing environment while the subscription supports remote Linkus access. This can be useful when trunks, analog interfaces, recording workflows, reception logic, or existing phones are still tied to the installed system.
Reduce Remote-Access Complexity
The service was created to make remote Linkus connectivity easier for S-Series users. That is valuable to smaller IT teams that do not want every mobile user to depend on manually maintained remote-access workarounds. Renewal preserves the architecture already used for the Linkus client connection.
Encrypted Service Transport
Yeastar describes LCS as an application-level tunneling service in which transmission between the PBX and tunneling server is encrypted and each PBX uses its own encryption key. For buyers, this means the remote communication design should be evaluated as a controlled service rather than an improvised exposure of the PBX to the public internet.
Support a Staged Migration Plan
Because S100 is end-of-sale, some businesses may prefer to renew for another year while they plan a replacement project, audit phones and trunks, select a new PBX, and schedule a controlled migration. A renewal can therefore serve as a bridge when immediate replacement would create operational or budgeting pressure.
Renew the Correct Service, Not Just a Similar Name
Standard Linkus Cloud Service and Linkus Cloud Service Pro are related but not identical. LCS Pro adds features such as a dedicated PBX domain name and Remote SIP Service for compatible remote SIP endpoints. An S100 owner who only needs Linkus client continuity may have a different requirement from a company trying to register remote IP phones, gateways, or a branch PBX. FourTeck can help the buyer describe the actual remote-working need before the renewal option is selected.
Important Renewal Highlights for Existing S100 Owners
This is a digital service renewal tied to an existing PBX environment, so the buying process is different from purchasing a boxed appliance. The most important identifiers are the host PBX model and serial number, the service already associated with that system, and the renewal period required. The service does not add physical ports, increase the S100 user capacity, or change the system into a hosted PBX.
The S100 itself was designed for 100 users with expansion to 200 and 30 concurrent calls with expansion to 60. Those capacities describe the PBX platform and are not created by the Linkus renewal. A buyer should therefore separate PBX sizing from service continuity: if the existing S100 is already undersized, a renewed remote-access subscription will not solve capacity pressure.
For remote working, standard LCS is centered on Linkus clients. Buyers who need remote registration of SIP desk phones, gateways, or branch PBXs should specifically discuss whether LCS Pro or a migration to a current platform is the better fit. This distinction prevents a renewal from being ordered for a requirement it was not intended to cover.

Choosing the correct renewal starts with the installed system, not with a generic license description. Confirm that the PBX is actually an S100, record the serial number exactly, and identify whether the existing subscription is standard Linkus Cloud Service or Linkus Cloud Service Pro. If the users only need Linkus mobile or desktop access, the requirement is different from a project that needs remote SIP phones or branch gateways. Also review whether the S100 still has enough user and call capacity for the next year. A company that has outgrown the PBX may gain more value from migration planning than from repeatedly extending a legacy platform. FourTeck can use these details to prepare a more relevant renewal discussion and, where appropriate, show a current Yeastar alternative.
Configuration and Buyer Guidance
For a renewal product, the highest-risk mistake is renewing the wrong service against the wrong PBX record. A short pre-check can save more time than trying to correct an activation issue later.
Which service is active now?
Check whether the current subscription is standard LCS or LCS Pro. The names are similar, but Pro includes additional remote SIP capabilities. A renewal request should match the existing environment or a consciously planned upgrade.
Is the PBX definitely S100?
Record the exact PBX model and serial number. Yeastar’s purchase process uses PBX identification, so a vague request such as “renew Linkus” is not enough for a reliable commercial check.
What do remote users actually need?
List whether staff use mobile or desktop Linkus, whether they need messaging and presence, and whether any remote physical SIP endpoints must register. That last requirement can change which service path is appropriate.
Will the S100 remain for another year?
Because the S100 is end-of-sale, renewal should fit the business lifecycle plan. If a replacement project is expected within months, align the renewal timing with migration so overlapping spend and rushed changeovers can be avoided.
Has the business outgrown the PBX?
Renewal preserves the remote service; it does not increase S100 capacity. If extensions, call concurrency, integrations, or branch requirements are approaching limits, review the platform itself before treating the subscription as the only procurement decision.
What should you provide for a quote?
Send the PBX model, serial number, current LCS plan if known, renewal quantity, target renewal date, delivery or billing location, and a short description of the remote-user requirement. Add any migration timeline if the S100 may be replaced.
Ideal Use Cases for an S100 Linkus Renewal
This renewal fits existing S100 deployments where the PBX still satisfies the core telephony requirement and the business primarily wants to keep Linkus remote access available. It is not automatically the right answer for every legacy S100 installation.
Hybrid Teams Using an Existing Office PBX
A company may have reception, finance, warehouse, and administration users in the office while sales and management work partly from outside. If the S100 still handles office calling effectively, Linkus renewal can keep remote staff connected to the same business extension environment without forcing an immediate phone-system replacement. This is especially practical where the business values continuity in call routing, extension numbering, voicemail, contacts, and established operating procedures.
Field Sales and Service Staff
Employees who travel between customer sites may need their business extension on a supported mobile device rather than relying only on personal calling. Linkus can help maintain a business communication identity while the S100 remains the central PBX. Buyers should confirm the current user workflow and client support before renewal.
Management Mobility
Managers frequently need to make, receive, transfer, or supervise business calls when they are away from their desk. An existing S100 deployment with Linkus can support that continuity. The renewal makes sense when the company is satisfied with the current PBX and wants another defined service period before broader modernization.
Bridge Period Before PBX Migration
An end-of-sale platform does not always need to be replaced the moment a renewal date arrives. A business may need time to audit extensions, choose new IP phones, verify trunks, prepare call flows, secure a budget, and schedule the cutover. A one-year service renewal can provide breathing room when used as part of a planned migration rather than an indefinite delay.
Distributed Users Without Remote SIP Hardware
Standard LCS is a good conversation to have when the requirement is centered on Linkus clients. If the project instead involves remote physical SIP phones, gateways, or branch PBXs, buyers should discuss LCS Pro or a current-platform alternative because that is a materially different remote-access requirement.
Yeastar S100 Linkus Renewal — Remote Client Continuity
The strongest reason to renew is simple: the organization still relies on remote Linkus users and the S100 remains suitable for its central telephony. Linkus brings office extension functions to supported desktop and mobile clients so staff can communicate without being physically beside a desk phone. For many businesses, this remote extension experience becomes part of daily operations rather than an occasional convenience.
Continuity matters because changing a phone system affects more than software. Users may need new logins, new mobile applications, new call-handling training, updated speed dials, revised routing, new integrations, and a coordinated cutover. If the company is not yet ready for that project, a renewal can preserve familiar working methods while a future migration is prepared properly.
The decision should still be evidence-based. Confirm how many people actively use Linkus, which client devices they use, whether remote access is business-critical, and whether the S100 has enough capacity for the expected next-year workload. Renewing an unused service or extending a PBX that is already operationally constrained would not be a good procurement outcome.
Yeastar S100 Linkus Renewal — Tunneling and Service Security
Yeastar describes Linkus Cloud Service as an application-level tunneling service. The tunnel handles SIP data and Linkus custom-protocol data rather than becoming a general path into the PBX. Yeastar also states that traffic between the PBX and its tunneling server is encrypted and that each PBX has its own encryption key. For a buyer, the important point is that remote Linkus connectivity has a purpose-built service architecture instead of depending entirely on ad hoc exposure of the PBX.
Security is still a shared operational responsibility. A subscription does not remove the need for strong extension credentials, current supported firmware, controlled administrator access, proper user offboarding, secure local networking, and review of any other services exposed from the PBX. The remote-working design should be considered as a complete system: PBX configuration, user permissions, internet quality, endpoint security, and the selected Linkus service all affect the final result.
Yeastar S100 Linkus Renewal — Lifecycle and Migration Planning
An annual renewal is easy to treat as a routine purchase, but S100 owners should use the renewal date as a lifecycle checkpoint. Yeastar ended sales of the S100 in 2022 and recommends the P560 as a replacement path. That does not automatically mean every functioning S100 must be removed immediately; it does mean the business should understand how long it expects to depend on the platform and what would happen if requirements change during the next service term.
A useful renewal decision therefore combines continuity and transition planning. Keep the service when it still solves a real remote-user need, but also document the installed phones, trunks, analog or digital interfaces, extension count, call concurrency, recordings, integrations, branch connections, and user workflows that would need to move to a future system. This turns the renewal from passive legacy spending into a controlled bridge toward a current platform.
Migration decision checklist
- Confirm whether the S100 is stable and correctly sized today.
- Estimate user, call, and branch growth for the next 12–24 months.
- List existing PSTN, SIP, BRI, PRI, GSM, or analog dependencies.
- Identify Linkus users and any new collaboration requirements.
- Check whether integrations or newer features are becoming important.
- Compare the timing of another renewal with a P-Series migration window.
What Buyers Should Check Before Purchase
The biggest renewal risk is assuming that every product called “Linkus” is interchangeable. Confirm the exact service attached to the S100, what users need remotely, and whether the legacy PBX is still the right platform for the coming year before placing the order.
Configuration Fit
Verify S100 as the host PBX, the current LCS plan, and the service expiration or renewal requirement. Standard LCS is centered on Linkus clients. If remote SIP phones, gateways, or branch PBXs are part of the requirement, discuss LCS Pro or a current platform rather than assuming the standard renewal covers them.
Compatibility Check
Confirm the exact PBX serial number, active firmware, Linkus client environment, internet connectivity, and user accounts. If the company is planning new phones, new trunks, a branch deployment, or a major network change, include those details because they can affect whether renewal remains the best approach.
Availability and Support Expectations
A digital renewal does not have the same logistics as a hardware item. Confirm current commercial availability, renewal eligibility, activation handling, the expected term, and any support scope before payment. Hardware warranty and subscription service are separate topics and should not be assumed to have the same coverage.
Quote Preparation
Provide the model, serial number, current plan if known, number of PBXs being renewed, target renewal date, company billing details, and UAE delivery or service location. Add the number of Linkus users and whether the S100 will remain in production for the full coming year.
Buyers should also think about long-term operating cost. One renewal may be reasonable for a stable installation, but repeated annual renewals on an end-of-sale platform should be compared with the cost and operational benefits of a current PBX. The right answer depends on how much existing infrastructure must be retained, how quickly requirements are growing, and whether the business wants new integrations or collaboration functions that are better served by the current Yeastar P-Series. FourTeck can review this context without forcing the decision into a simple “renew or replace” choice.
UAE Availability and Renewal Assistance
FourTeck supports enquiries for Yeastar subscription renewals in Dubai and across the UAE with practical pre-sales review. The service is useful when a customer knows the PBX model but is unsure which Linkus plan is currently attached, whether a standard renewal is still appropriate, or what information must be supplied for commercial processing. Availability can depend on the current subscription state, Yeastar service rules, supplier channel, and the exact PBX record, so confirmation should take place before the customer treats a quote as final.
For the quickest useful quotation discussion, share the S100 serial number, current Linkus service type if visible, expected expiration date, user count, and whether the business needs only Linkus clients or also remote SIP equipment. If the system supports a critical reception, helpdesk, sales, or branch workflow, mention the desired renewal date so continuity can be considered in the commercial plan. FourTeck can also provide guidance on related Yeastar PBX options when the existing S100 is approaching the end of its practical life.
Dubai, Abu Dhabi, Sharjah and Ajman Support
Businesses in Dubai, Abu Dhabi, Sharjah, Ajman, and other UAE locations can contact FourTeck for S100 renewal enquiries, compatibility review, commercial confirmation, and migration guidance. Because this is a subscription service rather than a physical appliance shipment, the most important first step is normally to identify the existing PBX and service record correctly.
Organizations with multiple offices should mention whether a single S100 or several PBXs are involved, which users rely on Linkus, and whether any branch uses remote SIP hardware. This helps separate a straightforward annual renewal from a broader multi-site communication requirement that may need a different Yeastar design.
GCC and Africa Renewal Enquiries
FourTeck also receives business technology enquiries from selected GCC and Africa markets. Companies in Saudi Arabia, Qatar, Oman, Kuwait, Bahrain, Kenya, Uganda, and other supported markets can use the relevant FourTeck inquiry channel to discuss Yeastar licensing, PBX replacement planning, and related communication requirements. Commercial availability, tax treatment, delivery or digital fulfillment, and support scope can vary by country and supplier arrangement.
For a legacy S100 renewal, regional buyers should provide the same core information: model, serial number, current subscription if known, quantity, required term, company location, and the communication need behind the request. Where the business is also considering a P-Series migration, include extension count, concurrent-call needs, trunk types, remote users, and major integrations so a current-platform discussion can be more useful than a simple replacement suggestion.
Other Options Buyers May Consider
A renewal decision often sits beside other questions: Is the S100 hardware still suitable? Does the company need Linkus setup support? Would a general renewal review help? Is it time to evaluate the current P-Series replacement path? These related FourTeck pages cover those different needs.
Yeastar S100 Dubai
Review the S100 platform page when the question is about the installed PBX itself, its capacity, telephony interfaces, lifecycle, or replacement planning rather than only the Linkus subscription.
Yeastar P560 IP PBX System
Yeastar identifies P560 as the recommended replacement path for S100. Consider it when the business wants a current appliance platform rather than another long-term dependency on the end-of-sale S-Series hardware.

Why Business Buyers Contact FourTeck
A subscription renewal can look simple on a purchase request, but legacy PBX licensing often carries hidden decision points. FourTeck’s role is to help the buyer define the requirement clearly enough that the quote reflects the installed environment and the intended outcome. For an S100 owner, that means understanding whether the business is renewing standard LCS, upgrading the remote-access approach, or preparing to move away from an end-of-sale platform.
This approach is particularly useful for procurement departments that receive a short internal request such as “renew Yeastar Linkus for one year” without the technical detail required to identify the correct service. FourTeck can help turn that request into a complete buying brief. It also gives the IT team a natural point to review whether the current S100 is still serving the organization well or whether the next renewal should be replaced by a migration project.
Yeastar S100 Linkus Cloud Service Renewal FAQ
What is the S100 Linkus Cloud Service renewal used for?
It renews the Linkus Cloud Service term for a compatible Yeastar S100 S-Series PBX. The practical use is to continue supported remote Linkus client connectivity for employees who need their business extension and communication functions away from the local office network. It does not replace the S100 hardware and does not convert the system into a cloud PBX.
Is this a one-year subscription?
Yes. The S100-LCS product is sold as a one-year Linkus Cloud Service license or renewal. The exact start and end dates, renewal eligibility, and commercial handling should be confirmed against the existing PBX service record. Provide the S100 serial number and current subscription information when requesting a quote so the correct term can be checked.
Does Linkus Cloud Service make my S100 a cloud PBX?
No. Yeastar specifically explains that Linkus Cloud Service is for its on-premises S-Series PBX and does not turn the PBX into a cloud-hosted phone system. The S100 remains the business’s on-premises PBX, while LCS provides a cloud-assisted tunnel for the Linkus remote communication experience.
What is the difference between LCS and LCS Pro?
Standard LCS supports the Linkus remote client experience for S-Series users. LCS Pro is an upgraded service that includes the LCS functions and adds a dedicated PBX domain name plus Remote SIP Service for supported remote IP phones, gateways, branch PBXs, and similar SIP endpoints. Buyers should match the renewal to the actual remote-access requirement.
Is the Yeastar S100 still a current-sale PBX?
No. Yeastar states that the S100 reached end-of-sale on July 1, 2022 and identifies the P560 as its recommended replacement path. Existing S100 owners may still have a valid reason to renew a service for continuity, but the renewal date is a good time to assess long-term platform risk and migration timing.
What information should I send FourTeck for a renewal quote?
Send the PBX model, serial number, current Linkus plan if known, required renewal term, number of PBXs, company location, target renewal date, and a short explanation of how remote users connect today. If the company may replace the S100 soon, include that migration timeline so the service term can be discussed in the right context.
Can FourTeck help if I am unsure which Linkus plan I have?
Yes, FourTeck can help structure the renewal enquiry by reviewing the PBX model, the service information available from the customer, and the remote-working requirement. Final eligibility still depends on the actual Yeastar service record and supplier channel, but a compatibility discussion can reduce confusion between standard LCS, LCS Pro, and current P-Series options.
Does renewing LCS increase S100 user or call capacity?
No. The renewal continues the Linkus Cloud Service term; it does not add PBX hardware resources or capacity. Yeastar lists the S100 at 100 users expandable to 200 and 30 concurrent calls expandable to 60. If the company is hitting capacity limits, the PBX platform and expansion or migration plan should be reviewed separately.
Can businesses request multiple renewals or project support?
Yes. Businesses with several S-Series PBXs, multiple sites, or a mixed renewal-and-migration project can contact FourTeck with the quantity, PBX identifiers, locations, user counts, and target dates. The requirement can then be separated into renewal items, current-platform replacements, configuration services, and any supporting telephony work that needs its own scope.
Where can I request this renewal in Dubai or the UAE?
Contact FourTeck through the UAE contact page with the S100 serial number and renewal details. FourTeck can assist with quotation, service identification, compatibility questions, and lifecycle guidance. Final commercial availability can vary according to the PBX subscription status and supplier channel, so confirmation is completed before the renewal is treated as finalized.
Need Help Renewing the Correct S100 Linkus Service?
FourTeck can review your existing S100, current service type, serial number, remote-user requirement, renewal timing, and migration plans before preparing a quote. This is particularly useful when the business is unsure whether standard LCS, LCS Pro, or a current Yeastar platform best fits the next stage of its communication environment.
Share the PBX model, serial number, current Linkus plan if known, quantity, target renewal date, business location, and how remote users connect today.
