I have a prospect with 7 incoming fax lines over AT&T SIP trunks. They need to be processed differently based on incoming DID. My plan is to get them to a server with a smar modem. The fax volume is not great, it's just that the client needs a lot of lines for business reasons.
1. Can I send several incoming fax DIDs to a single FXS port on a UC?
2. Can I encode the DID into DTMF tones which a fax card in a server will convert back to DIDs for processing decisions?
3. Any other solution recommendations?
