I have a trunk SIP from OVH provider, I want to use my DID number for receiving (fax2mail)/sending Fax.
I have also Grandstream GXW4104 connected to 4 analog lines, how can I receive(fax2mail)/send a fax from this gateway?
Which is the best configuration to use for my needs?
Should I use the spandsp?
Note: the asterisk that I’m using is 1.8.15 (certificate version)
