BYO SIP TRUNKING
SIP Call Issue – Inbound Going to Voicemail, Outbound Call Tool Not Found
Hey everyone — I’m setting up SIP integration for my voice agent using Vapi and running into two key issues:
What’s Happening:
What I’ve Done:
Integrated a SIP trunk from a local Caribbean provider
Used standard settings (UDP, PCMU/PCMA codecs, RFC2833 DTMF)
Created a voice agent and assigned the SIP connection
Double-checked auth, domain, and credentials (all correct)
Questions:
What might cause inbound calls to skip Vapi entirely?
What does the “Tool ID does not exist” error mean? Is it related to a missing config or voice agent?
Appreciate any help or direction!
