Hello I have a Asterisk 11.5.0 with libss7 and Sangoma A104DE digital interface card . The operating system is Centos 6 We are using this server to terminate calls to Telco. So calls are coming to asterisk from sip and we are sending calls to Telco with Dahdi. (It is a one way interconnection only from asterisk to telco ,not from telco to asterisk) We are experiencing some difficulties with T38 faxing. I set t38pt_udptl=no in [login to view URL] . So as far as i understood if a call to sip sends T38 invite then asterisk should send SIP 488 Not acceptable here and the sip side will either fallback to onether codec or disconnect. In my case although i set t38pt_udptl=no in peer configuration asteisk is sending SIP 200 OK with sdp G711 to the invite of T38. I also tried to set t38pt_udptl = yes,redundancy,maxdatagram=400 and setvar=FAXOPT(gateway)=yes,20 in [login to view URL] but still i couldn't manage to receive fax We are looking for professional support to solve this problem. Asterisk server is behind nat and neccessary ports are directed on router to ip of asterisk. Everything except fax is working fine. The server is in production and necessary modifications that will interrupt the calls on the server will be done on off-peak hours. I need an experienced freelancer that will be %100 sure that he/she is able to solve this or did similar solutions in the past. Best Regards
