[Serusers] re: Malformed CONTACT field in 302 response

by Jignesh Gandhi

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

[Users] mysql database accounting problems

by Tanguy Bouzéloc

Hello, I've some issues with my mysql accounting, I can only log successful calls in the acc table and I've no informations about missed calls. In mysql accounting I've only sip 200 ok and no errors. I've not this behavior in my syslog. It's very important for us for evaluate the performance of our providers and we can only do it with a database accouting. For example, If I pass a call and I let it ring til operator timeout, I've no trace of this call in the accounting table. I've also another question, the lcr and gw tables have very small fixed limits (256 for lcr and 32 for gw), since we have much more gateways and sdas I've updated theses limits to a value which fit our needs, do you thinks it can be a problem ?

[Users] Cisco/OpenSER called number issues after ENUM lookup

by Luca Corti

Hello, I've got an AS5350 receiving calls on ISDN E1 and forwarding calls to OpenSER. At the moment ENUM translations are performed on the AS5350 and calls received by OpenSER already contain the correct SIP URIs. Unfortunately I verified that the called party number information is lost in the process and at the called side I cannot distinguish numbers if I associate multiple PSTN numbers to the same sip user. I guess this is Cisco's fault, since it should add a Remote-Party-ID of type "called" to the INVITE. Do I have to move ENUM mapping to OpenSER or is there a quicker solution? thanks Luca

Re:[Users] how to handle 302-moved temporarily
