User experiencing silent calls after 2 rings

[TLCtech]

I have a user that says they are trying to call out, and instead of ringing, the sound cuts after two seconds. The user says it will ring twice, sometimes longer, and then the line will go dead, and will sometimes skip to VM or the person answering. Other times it will remain dead indefinitely until they hang up. This happens on both mobile app and web app. They can disconnect the call and try again and its fine. I have not been able to replicate this as of yet. And I dont see anything in the logs to suggest something is happening. To help mitigate the issue, I enabled PBX delivers audio, but iirc since its hosted, that wont matter? So far it hasnt fixed it.

Any help is appreciated.

Hi there.
Does it happen to you only when you call external number?
If you call another local extension, do you face the same issue?

It only happens when this user calls outside the office. So far, calling internal ext are fine.

Yes, callcentric is still on that list. At least for now.
