SIP/SMS with FreePBX
From VoIP.ms Wiki
This page will detail the basic configuration required in order to send and receive SMS messages through FreePBX
The information in this page is based on the newer Chan_PJSIP channel driver. This is because the older Chan_SIP driver does not correctly implement authentication for SIP messaging, which is mandatory with VoIP.ms servers for security reasons. We therefore assume the following:
- You have configured your FreePBX so that it has a PJSIP trunk that is registering with one of the VoIP.ms POPs (Point of Presence).
- You have added a PJSIP Extension to your FreePBX configuration, with appropriate routes for sending and receiving phone calls.
- You have a soft-phone that is configured for registering with the above FreePBX extension, for making and receiving phone calls. This soft-phone also has the ability to send and receive SIP text messages.
