Hey Guys,
I was wondering if someone can help me with identifying my issue (which I suspect it as a bug).
I am doing some redirect tests between 2 servers, both running same Kamailio version - 4.0.0 out of debian packages. """ root@IECDev:/home/dan# kamailio -V version: kamailio 4.0.0 (x86_64/linux) flags: STATS: Off, USE_IPV6, USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 4MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled on 13:13:24 Mar 29 2013 with gcc 4.7.2 """
On redirect server I have location stored, doing lookup and right after using "sl_send_reply("302", "iClass4-AP Redirect");"
Up to information stored in the Contact of redirect request everything works smooth, the problem which I get is with the information in the Contact of the redirect: """ # U 2013/05/27 16:55:39.171237 127.0.0.1:5070 -> 10.10.10.21:5060 SIP/2.0 302 iClass4 AP Redirect.

"""
It appears that the information of the first contact is correctly encapsulated but the second (out of first branch) not.
Due to this in the server capturing the redirect I will only have first contact correctly written in the ruri and second one partially. Example of loging this: """ May 27 16:55:39 IECDev /usr/sbin/kamailio[3556]: ERROR: <script>: Extracted destination set: Contact: sip:dan@10.10.10.154:5060;q=0.01, sip:dan@10.10.10.141:3072;line=qhjb2bk0;rcv=sip:10.10.10.141:3072;q=1, ru: sip:dan@iec.itsyscom.com, du: sip:127.0.0.1:5070 May 27 16:55:39 IECDev /usr/sbin/kamailio[3556]: ERROR: <script>: Branches: sip:dan@10.10.10.154:5060;q=0.01, sip:dan@10.10.10.141:3072;line=qhjb2bk0;rcv=sip:10.10.10.141:3072;q=1 """.
I would suspect the redirect function not properly inserting the content of each contact uri within it's own <> boundaries but I would appreciate a confirmation on this from someone more experienced with Kamailio's code.
Thanks in advance for any tip!

Hello,
apparently the rule of enclosing uri in between <> was wrong, done only when q was set. I changed to do it always, to protect the uri parameters.
Can you try with the patch from commit: - http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=74bf08ef...
If nothing is broken, I will backport to stable branch.
Cheers, Daniel
