i imported telnyx phone number into vapi connected it to an assistant but now it doesn'tsay anythin beyond first message why? ,this is the caller id:20519800-9533-4924-b432-c279ceb048fc

Check your assistant's server endpoint configuration. If your assistant uses a server endpoint for personalization, make sure your endpoint responds within 7.5 seconds and returns the correct format. For example:

json
{
  "assistantId": "your_assistant_id"
}

If the endpoint is slow or returns an error, the call may not proceed beyond the first message. Review your server logs and endpoint availability to resolve this issue. Source: - [Personalization with user information (Vapi docs)](https://docs.vapi.ai/assistants/personalization)

it works when i change the number to vapi free number but on telnyx it doesn't

Check your Telnyx number's "Translated Number" setting. In the Telnyx portal, edit your number, go to Voice settings, and set the "Translated Number" to your Vapi SIP URI (e.g.,

sip:your-unique-id@sip.vapi.ai

).

text
Translated Number: sip:your-unique-id@sip.vapi.ai

This ensures SIP INVITEs route correctly to Vapi and should resolve the issue where calls stop after the first message.

Hey can you send me latest call_id? So, that I can take a look into it.

here it is 294e53c8-c3d7-406b-9102-560a475680c6

Please check your Telnyx number's "Translated Number" setting: 1. In the Telnyx portal, edit your number. 2. Go to Voice settings. 3. Set the "Translated Number" to your Vapi SIP URI, for example:

sip:your-unique-id@sip.vapi.ai

This ensures SIP INVITEs are routed correctly to Vapi and should resolve the issue where calls stop after the first message.

Hey, I looked into the shared call ID, call logs, and as well as listen to the call recording, there is no user audio coming in. So that leads to assistant going silent. In case you feel like, "This is not true, the user is speaking something on the call," I'll suggest you to share more, few more call IDs so we can continue our setup investigation. If you want to confirm the same, you can check with the Telnyx team as well. I am sharing their call ID associated with this call.

telnyx_Call_id

v3:24n49iclRLxqySHY8oN6snPbAUKHZgKZGHbVTaWs-ry5XKBaOS45UQ

here is another one today: caller id :483f332c-037c-4042-9f4f-ed947a44714e ,the user makes the call but after first message it doesn't speak ,secondly its a telnyx number but in vapi its showing vonage ,why?

To help diagnose further, could you please confirm if your Telnyx number's "Translated Number" is set exactly to your Vapi SIP URI (e.g.,

sip:your-unique-id@sip.vapi.ai

) in the Telnyx portal's Voice settings? This is a common cause for calls not proceeding beyond the first message ([see official guide](https://docs.vapi.ai/advanced/sip/telnyx#configure-sip-invite)).
