❓Anyone experienced this with Telnyx + Vapi?
I’m using a Belgian number via Telnyx SIP for an AI outbound voice agent (built with Vapi).
Inbound works perfectly after disabling G722 in Telnyx
Outbound from a Dutch number = perfect
Outbound from the Belgian number = horrible audio / noise / agent can’t understand
Telnyx says they changed routing, no effect.
⚙️ Could this still be a codec mismatch (G722)?
👉 Anyone know how to resolve the issue, or how to force PCMU/PCMA only from Vapi for outbound SIP calls?
Or had similar issues with Telnyx routing on Belgian numbers?
