FAQs

Interested? Do you have questions? Check out some of the questions we’re most frequently asked to discover more. If you still can’t find what you are looking for, get in touch – and we’ll be glad to answer your query.

Can I replace my legacy SMS solution?

Yes, WTL supports both classical, SS7-based and IP-based messaging. You can retire legacy platforms, adopt WTL’s SMSC platform – and extend the same platform to cover your IP networks and IP-enabled UEs.

Does your VoLTE solution comply with GSMA requirements?

Our VoLTE / ViLTE and VoWiFi solution is fully compliant with all relevant GSMA and 3GPP standards, which means you can deliver a complete service for your customers. It will evolve hand-in-hand with the specifications, so you can easily maintain compliance as you upgrade your network.

Can I add VoNR when I have moved to a 5G core?

WTL’s VoLTE solution also offers full support for the IMS-based 5G New Radio service, so you can easily add support for this when you need to do so.

Do your SMS and VoLTE solutions scale?

Our architecture enables seamless scalability – so you easily support service growth. You can run our solutions alongside legacy platforms and migrate users as IP-UE penetration increases, or swap out legacy infrastructure to converge on WTL’s solution set.

We plan to replace our IMS soon. Is that a problem?

Not at all. We have proven interoperability with different IMS platforms, so you can deploy our IMS service solutions today and migrate to a new IMS core whenever you like.

To which standards do you comply?

From GSMA, we follow PRD IR.92 and PRD NG.114, for example, while we also adhere to 3GPP TS 23.204 and TS 23.228, among others, for the overall IMS architecture and service principles. For a full list of standards we support, please ask our team.
