SIP - Information Needed to Build a SIP Trunk

In order to build a SIP Trunk, we require the following:

- Make/Model of the PBX that will be used

- Digest or IP Authentication must be specified

- Digest means they will authenticate using a username and password

- If IP Authentication is chosen, please provide a public, static IP address

Attached to this article is a list of PBX makes and models that are currently in our database. If you do not see the Make/Model the customer is requesting, please send an email to support@calltower.com
