🚨 Issue with Telnyx Integration – Error 401 in Vapi Hey team, I’m trying to connect my Telnyx number to Vapi and keep hitting this error: Error in Importing the Phone Number "Couldn't Update Telnyx Number. Error: Request failed with status code 401" ⚙️ What I’ve done: I’m using the number: +1-682-428-5796 Clicked Import from Telnyx in Vapi. Gave it a label: Wholesaling Agent Phone Number API key from Telnyx is confirmed active and valid on their side. The number is assigned to a Voice Application inside Telnyx. ❓ What I need help with: Is there a specific permission or scope the Telnyx API key needs to have? Do I need to configure a Webhook or SIP connection manually? Any specific headers or formats Vapi expects when connecting to Telnyx? I’ve attached a screenshot of the error. Would love some guidance on how to get this working — I just want Vapi to use my Telnyx number for outbound calls. Thanks in advance!
