Vapi helps developers build, test, and deploy voice agents at scale. We enable everything in between the raw models and production, including telephony, test suites, and real-time analytics.
I couldn't find enough info on integrating a T-Mobile business number with Vapi, so I'm escalating this to a human expert for you!
Just so you know, Vapi has guides for integrating numbers from Twilio (see here) and Telnyx (see here), but nothing specific for T-Mobile. Hang tight—someone from the team will get back to you soon!
