At Star Telecom, we’ve had the opportunity to work with a number of stand-alone AI platforms in the CX space. One thing that’s become clear to me is that there is a significant knowledge gap when it comes to SIP and most AI platforms.
At best, they’re using a Telecom Platform as a Service (TPaaS) as the SIP integration layer, with all its limitations (and features), along with the privacy, data residency, and data sub-processing concerns this creates.
At worst, they have someone who learned the basics of an SBC, or perhaps got certified on one, but with very little background in telecommunications and SIP as a discipline.
For all the effort going into architecting AI to be everything it can be, precious little is going into long-term planning around voice and telco, which still drives a material volume of customer interactions.
The redundancy, resiliency, and security considerations that used to underpin every telecom discussion are seemingly taking a back seat.
This may work for now, while AI solutions remain POCs, pilots, and bolt-ons. But as soon as the current land rush ends and AI becomes the main course, the architectural immaturity of AI voice will come back to bite. Think about what happens when:
- Your AI voice platform has no geo-redundancy, and the single cloud region it depends on goes down — as happened with the AWS outage in October 2025, which took out communication platforms globally for hours.
- Your AI-to-agent call transfers are failing 40–60% of the time because nobody architected proper SIP REFER or warm handoff flows — and customers are being dropped mid-conversation or forced to repeat themselves.
- Your SIP trunk provider suspends your account overnight because your AI’s short-duration, high-frequency call patterns triggered their fraud detection — and your entire outbound operation grinds to a halt with no recourse.
- Your voice data is quietly transiting through regions outside your compliance boundary — because the AI platform routes audio through whichever media server is fastest, not whichever is compliant.
- A production SIP integration that worked fine in testing starts throwing 400 errors at scale — as multiple teams running OpenAI’s Realtime API over Twilio SIP trunking discovered in early 2026, with more calls failing than succeeding and no webhook events to debug.
None of these are hypothetical. They are happening now, at the edges of production. They just haven’t hit the mainstream yet because most deployments are still small enough to paper over.
If you’re deploying or assessing AI platforms, make sure you apply the same due diligence you would to your telecom provider, because one day, they may be exactly that.
