HI, WE are having problems with t.38 fax and record-route in SER. Without record_route, using only t_relay(), fax works fine between two of our UA's. However, when record_route is used, a voice call is successful but a fax call fails. An ethereal sniff shows that the "re-invite" from the destination to the origination is never forwarded to the origination UA. Thus, the fax fails. If I turn off record_route(), the fax call succeeds. An ethereal sniff of the failure case is attached. A snip of the ser.cfg file which shows the use of record_route() and t_relay() is attached. If I comment out the one line for record_route(), the fax succeeds. Any ideas as to why this fails? thanks bert -- Bert Berlin Director, System Test Quintum Technologies, Inc. 71 James Way Eatontown,NJ 07724 ph 732-460-9000 ext 247 ------------------------------------------------------------------------ if (uri==myself) { #look for the registered contact in the location table of database #and if find it, rewrite the uri and forward statefully to the destination if (lookup ("location")) { record_route();#send everything back through the proxy t_relay(); break; } ------------------------------------------------------------------------ _______________________________________________ Serusers mailing list serusers(a)lists.iptel.org http://lists.iptel.org/mailman/listinfo/serusers
