[Freeswitch-users] fax@pstn with freeswitch

Hello list, Since I tested the last year lot of T38 implementation with cpe, asterisk etc.pp. with lots of problems, I would like to have a solution to handle the fax issue with pstn. How is the mod_fax integrated with freeswitch? Is there a kind of "softmodem" needed, or could fax directly handled on a circuit of a sangoma E1 card? I would like to build a kind of routing device which could handle DDI correctly and is able to hold calls on TDM for fax. Example: I have a kind of numbers like 12345-[0-6] The user has a fax number on 12345-523 and 12345-455. Then I would like to handle 12345523 => fax-mod@tdm 12345455 => fax-mod@tdm 12345[0-6] => SIP BR Uwe -- kiste lat: 54.322684, lon: 10.13586
