Configure your Trunk using Twilio Interconnect

Twilio Interconnect allows you to connect your SIP infrastructure using a private connection (e.g. MPLS, cross-connect) to a Twilio Elastic SIP Trunk.

Configure your Trunk using Twilio Interconnect

Termination settings for Twilo Interconnect

To connect over Twilio Interconnect, point your communications infrastructure to the following localized Termination SIP URIs:

Origination settings for Twilio Interconnect

Configure your origination SIP URI, which identifies the network element entry point into your communications infrastructure (e.g. IP-PBX, SBC). To ensure your calls go over your private connection include the tnx parameter in the URI with the value of the desired Twilio Interconnect connection, for example:

• sip:172.56.42.132;tnx={TNX_SID}
• sip:mysbc.com;tnx={TNX_SID}

Note: without the {}, for example:

• sip:172.56.42.132;tnx=TN0101161007021654ec45d737b6290d51
• sip:mysbc.com;tnx=TN0101161007021654ec45d737b6290d51

You can use multiple origination URIs for failover where you can have a primary URI send traffic over Twilio Interconnect, and a secondary URI send traffic over the public internet in the case of failure.

IP Addresses using Twilio Interconnect

We strongly encourage you to allow all of Twilio's following IP address ranges and ports on your firewall for SIP signalling and RTP media traffic. This is important if you have Numbers in different regions and for resilience purposes (e.g. if North America Virginia gateways are down, then North America Oregon gateways will be used).
