I've been testing the exchange of FAXes in Asterisk 1.4 using T.38, and I found that it only works if I use canreinvite=yes for both ATAs connected to my legacy FAX machines. The so called T.38 passthrough is only for SIP signaling? Not for RTP? If so, is there a way I can make the RTP traffic of those FAXes go out using the same IP of my Asterisk server through the SIP trunk I have established with the telco I have subscribed? This is because, this telco only accepts all traffic (SIP+RTP) sent by the same IP. Regards, Ricardo Carvalho. -------------- next part -------------- An HTML attachment was scrubbed...
