I have a system that has 2 pots lines that need to be added to FusionPBX. These are 2 numbers outside of my sip provider that are our main numbers. We were unable to port them over so I purchased a Sangoma B600DE card for them. I added the wanpipe driver and freetdm to freeswitch. My question is how do I configure Fusionpbx so that we can receive inbound calls on these 2 numbers.
