Hi I'm working on a platform for a client where I do calls for them using the vapi voice agents. The numbers are imported from telnyx through sip trunking. There are multiple issues that need to be resolved. 1. One of them being the latency, it's sometimes around 4-5 seconds, and most people end the call thinking that there's no one responding. 2. Inbound calls seems to be not working. 90% of them end after agent greets the receiver, and yet the call status shows that customer ended the call. So it's confusing what's going wrong 3. In some calls agent keeps speaking but it seems like customer doesn't hear it as they keep saying hello. Some of the call ids: 019a956e-285b-7003-90a0-65a177cc900b 019a9527-2ecd-711a-a40d-d76e31331268 019a951f-ae4f-7229-a61c-a7426dcf94b4 019a951c-ac9a-7113-80b6-68d4291d1930 019a94ff-cb1a-7aa3-88f8-49b89fcc3cd7 019a94f4-a22c-7881-9ab0-986c4ed2ac43 019a94ed-6669-7551-acce-5ddc38894aab 019a7115-f015-7995-9fb0-ab927b8479bd Need to get this resolved as it affects my clients badly

To address inbound call failures, first double-check your Telnyx SIP trunk and Vapi inbound configuration. Make sure your Telnyx number is assigned to the correct SIP trunk and that the SIP invite is set to your Vapi SIP URI. For example:

plaintext
Set "Translated Number" in Telnyx Voice settings to: sip:<your-unique-id>@sip.vapi.ai

This ensures calls are routed correctly to your Vapi agent. For full steps, see the [Vapi Telnyx SIP integration guide](https://docs.vapi.ai/advanced/sip/telnyx). Source: - [Telnyx SIP integration](https://docs.vapi.ai/advanced/sip/telnyx)

Already setup the sip trunks correctly, they are even routed the the Australian SIP URIs for better latency

I have the same issue when just using the native Telnyx import. Have you found a fix yet?

Nope no fix at the moment. Tried multiple workarounds but nothing resolves it

From the audio recordings, we are clearly seeing a latency issue between the users speech and the assistant, which is resulting in the users not hearing the assistant. The call is ending because of the customer or the provider sending a BYE packet to VAPI. What other methods/workarounds have you tried?
