Importing Telnyx Number Fails
When I go to Phone Numbers → Create Phone Number → Import Telnyx, I enter my correct Telnyx number and API key (verified and regenerated multiple times), but clicking “Import from Telnyx” always gives this error:
Error in importing Telnyx Phone Number
Incorrect Telnyx Credential.
The credentials are definitely correct — I've double-checked and tested them in Telnyx directly.
However, when I try to enter that into the “Translated Number” field under Voice Settings for my number in Telnyx, it returns an error:
Must contain only letters and numbers; no spacing allowed
There are no spaces in the URI, so it seems like either Telnyx has changed their validation or your docs are outdated and unclear.
At this point, I’ve lost hope of getting my Telnyx number connected to Vapi. Would really appreciate some guidance or an update if there’s a workaround.
