Connecting a Telnyx Number

Telnyx works either way — it can send calls to us, or we can sign in to Telnyx as a SIP credential. Pick the one that matches how you already run the number.

Sending calls to us (FQDN connection)​

  1. In the Telnyx portal create a SIP connection of type FQDN.
  2. Set its destination to sip-trunk.abacus.ai on port 5080.
  3. Set the connection's number format to +E.164, so the number arrives with its country code.
  4. Assign your number to that connection.
  5. In Abacus.AI, connect the number with Fixed IP addresses and enter the signalling addresses Telnyx documents for your region.

Letting us sign in (credentials connection)​

  1. In the Telnyx portal create a SIP connection of type Credentials, which issues a username and password.
  2. Assign your number to that connection.
  3. In Abacus.AI, connect the number, choose It's on my phone system, and enter sip.telnyx.com as the provider SIP host with that connection's username and password.

Registration takes about a minute, after which the number's row reads Registered to your provider.
