Delay on Outbound Calls via Telnyx Compared to Twilio

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 šŸ™
