Hey folks so I grabbed a fresh Telnyx number (HD quality, never used before, etc.), everything looks good, but I'm getting a solid 8-9 second delay on outbound calls from Vapi (delay of the agent to answer) Same exact setup (same assistant, tools, flow), but when I switch the number to a Twilio one, the delay drops to like 1 sec or less, super smooth! Interesting part is when I get the recording from Vapi, its like "stitched " perfectly without the delay gaps you can clearly experience on the phone call. The record sounds perfect, but it wasn't like that on the call.. Twilio:

c992400a-87e6-4cd0-9bc1-96f8da75f8ac

| time: 1751654238450 Telnyx:

963c3c94-7c26-4c8b-b710-6ef38ee72b05

| time: 1751654107674 From the recording it feels like the audio was sent but not received. Really want to get this working with Telnyx, anyone else run into this? is there a fix or a setting I’m missing? Appreciate any help 🙏

Check SIP traces, adjust vapi endpoint settings like codec and jitter buffer, and contact Telnyx support to optimize call routing or reduce post-dial delay..

Did you solver the issue? I'm facing exactly the same problem
