Hey
I’m running into a couple of issues while setting up my Telnyx SIP number with Vapi, and I’d love your help!
I added the number via the API following the Telnyx integration docs:
https://docs.vapi.ai/advanced/sip/telnyx#4-add-your-telnyx-sip-credentials-to-vapiai
Everything looks good — the number appears in my dashboard and it's marked as active.
Problem 1:
When I try to select my assistant in the Outbound Settings, I can choose it in the dropdown, but the value doesn’t get saved.
No error shows up — it just resets after selecting. I’ve tried multiple browsers, same result.
Is this a known UI bug? Should I assign the assistant another way (e.g. API)?
Problem 2:
Possibly related — I can’t make outbound calls.
The call attempt fails and I get this in the logs:
An error occurred in this call: call.in-progress.error-sip-telephony-provider-failed-to-connect-call

Thx
