sean Posted December 4, 2009 Report Share Posted December 4, 2009 I need some help in sending fax through pbxnsip. (We'll deal with receiving a fax later Our setup: Internetprovider with SIP-GateWay (QSC), supports t38 pbxnsip v 220.127.116.1177 ATA (SPA2102), supports t38 Faxmaschine Our problem: We have enabled the speaker on the fax to listen in. When we register the ATA directly at the SIP-gateway of our provider, everything is perfect. When we register the ATA in pbxnsip (with identical settings), the following problem occurs: Fax is dialing, remoteparty is ringing, remoteparty picks up, our fax is sending CNG, and that's it! No CED from remote party is recieved. After a timeout the connection is terminated. The pbxnsip log and the statusinfo on the ATA show, that first the G711 codec is used and then it switches over to t38. It seems the remote fax is not recieving our CNG and therefor is not sending the CED. Find attached an example logfile and a screenshot of the configuration of our ATA. Any help would be greatly appreciated Cheers, sean pbixto_fax_log2.txt Quote Link to comment Share on other sites More sharing options...
