Hello, I am using SER as a redirect server. I recently posted almost the same question. This time the format of the CONTACT is different. It contains call information. Recently I came across an issue where the 302 sent back by SER is not liked by a soft switch. Particularly , the format of the CONTACT field according to the softswitch.. Here is an excerpt of the 302 reply send back ... Session Initiation Protocol Status-Line: SIP/2.0 302 MovedTemporarily Status-Code: 302 Resent Packet: False Message Header Via:SIP/2.0/UDP 70.167.132.2;branch= z9hG4bK-BroadWorks.70.167.132.2-172.20.20.46V5060-0-476027561-38657848-1175625610577 - From:"7000 Arris-EMTA-SIP"<sip:6782347000@70.167.132.2 ;user=phone>;tag=38657848-1175625610577- SIP Display info: "7000 Arris-EMTA-SIP" SIP from address: sip:6782347000@70.167.132.2 SIP tag: 38657848-1175625610577- To:<sip:+16782349999;csel=noind@172.20.20.46:5060;user=phone>;tag= b27e1a1d33761e85846fc98f5f3a7e58.4baf SIP to address: sip:+16782349999 SIP tag: b27e1a1d33761e85846fc98f5f3a7e58.4baf Call-ID:BW144010577030407-1243907316@70.167.132.2 CSeq:476027561 INVITE Contact: sip:+16782349999;csel=noind@172.20.20.37 :5060;user=phone;transport=udp Server: Sip EXpress router (0.8.14 (i386/linux)) Content-Length: 0 the softswitch is wanting the contact field with <sip:xxxx@xxx.xxx.xxx.xxx:5060> like a FROM or TO URI. It is claiming that since it contains call information within the sip URI, it should be enclosed withing < >. Here is ser.cfg part that does the sl_send_reply(); # do a stateless redirect, if return code is correct if (method=="INVITE") { xlog("L_INFO", "SourceIP <%is> \n"); xlog("L_INFO", "From-uri<%fu>, r-uri <%ru> \n"); if (!gl_redirect()) << custom function that just gets a Server to redirect to { sl_send_reply("480", "TemporarilyUnavailable"); xlog("L_WARN", "Sending a 480 response with r-uri <%ru>\n"); break; } else { sl_send_reply("302", "MovedTemporarily"); xlog("L_DBG", "Sending a 302 response with r-uri <%ru>\n"); break; } }; Any help is appreciated.** thanks, -- Jignesh Gandhi jigpgandhi(a)gmail.com
