Get your Telnyx SIP credentials
- Log in to the Telnyx Portal
- Go to SIP Trunking → SIP Connections
- Create a new SIP connection
- Note the SIP Connection URI and Outbound Voice Profile
- Under Authentication, set up SIP credentials. As an additional layer, you can also allowlist the static SIP IP ranges (
143.223.88.0/21,161.115.160.0/19) — these are shared egress ranges and should complement credentials rather than replace them
