Hi, I'm getting Call.start.error get transport on all outbound calls from a Canadian Telnyx number (+1 819 200 0980). Setup: Telnyx number imported in Vapi (Phone Number ID: 31fba227-2f27-4faa-b1b5-10fa1c957084) Assistant ID: 09decad8-3fd8-4381-8bd9-ea9a97f05995 Outbound Voice Profile in Telnyx has the Vapi Voice API App assigned Telnyx Programmable Voice App is active and pointing to Vapi webhook What I tried: Re-imported the number with a fresh Telnyx API key Tried updating credentials in Integrations → Telnyx → getting error: "property telnyxApplicationId should not exist" All calls show $0.00 cost and N/A duration — fails before connecting Question: Is there a known issue with Canadian Telnyx numbers? Is telnyxApplicationId no longer a valid field in the credentials payload?

This isn’t a Canada-specific issue that call.start.error-get-transport usually means Vapi can’t establish a transport with Telnyx at all, so the call fails before it even connects. Given your setup, it’s most likely a config mismatch rather than the number itself. Double-check that your Telnyx connection is actually set up as a valid transport (SIP/app) and properly linked to the outbound voice profile, because without that Vapi won’t be able to initiate calls. Also, that telnyxApplicationId should not exist error suggests the credentials format has changed so yes, that field is likely deprecated and causing the integration to break. I’d focus on fixing the transport layer (SIP/app linkage + credentials) once that’s correct, the calls should stop failing at $0.00. @Phil
