[Kamailio-Users] registrar lookups without reason
by jh＠tutpro.com 02 Sep '09

02 Sep '09

when analyzing the weird problem, where request uri gets rewritten with aor's contact even when there is no command in config file that would do it, i noticed these lines in syslog: Aug 31 16:41:50 /usr/sbin/kamailio[23139]: DBG:core:rewrite_uri: rewriting Request-URI with 'sip:foo.bar@ip-address:5060;transport=UDP' Aug 31 16:41:50 opensipg /usr/sbin/kamailio[23139]: DBG:registrar:lookup: 'foo.bar@ip-address' Not found in usrloc Aug 31 16:41:50 opensipg /usr/sbin/kamailio[23139]: DBG:registrar:lookup: 'foo.bar@ip-address' Not found in usrloc any one has any idea why lookup was called even when it is not in the script? this is getting very weird. looks like kamailio is executing statements on its own. -- juha

[Serusers] CANCEL passed through SER is occasionally ignored by destination switch
by Frank Durda IV 02 Sep '09

02 Sep '09

I have a situation where CANCEL messages sent by the caller through SER are sometimes ignored by the destination switch. These events are infrequent, and seem to be ignored only if they are received in a narrow window between the 100 Trying and the 183 Session Progress or 180 Ringing message. The destination switch eventually emits a 183/180 and even a 200 OK as the called party answers the call of a long-departed caller. I don't believe that this is a race condition, as the called numbers are sometimes wireless parties, who have 4-10 seconds of time between 100 Trying/IAM and 180/183/ACM responses, and I have seen ignored cancels at the beginning and middle of that lengthy period. So a race condition for that large a period with such an infrequent occurrence seems unlikely. The destination (SIP to ISUP gateway) equipment vendor points out that in the dozen samples of this occurring that the branch tag of the CANCEL didn't match the one shown in the INVITE, and per RFC 3261, their decision to ignore the CANCEL seems to be the right one. In particular, section 17.2.3 criteria 1. This immediately made me think of SER and its habit of saving time and memory by not remembering some or all call state unless you tell it to, via various knobs that are turned off by default. However, I can't explain why most cancels that arrive in the same point in the call setup apparently do meet criteria and only a small number don't. It would seem that SER would have mismatched branch tags all the time or never, depending on the knob settings. Any ideas? Thanks in advance.

[Kamailio-Users] Symmetric NAT
by David 01 Sep '09

01 Sep '09

Hey, So I have setup a Kamailio server, it works well with most devices, but works terribly with Symmetric NAT. If you haven't already guessed, I am using STUN for NAT traversal. Could some people share there experiences with Symmetric NAT ? I see a lot of places saying that STUN is not good with it, but I haven't found a lot of suggestions for how to handle it. Thanks, David

[Kamailio-Users] LCR questions ( ping and flags columns )
by Ricardo Martinez 01 Sep '09

01 Sep '09

Hello list. I have a couple of questions about the LCR module. The first one is about the "ping" column in the gw table. I guess this column stores the "results" of execute a ping to the gateways in the LCR.gw table isn't?. So how this "ping" is executed? It is just a simple ICMP message? Or maybe is an OPTIONS sip message to the gateway?. I saw in the lcr_mod.c file some ping_method, ping_interval variables, but in the README file there is nothing about the "ping". Could someone clarify this to me this? Second. In the mysql "gw" table there is a column called "flags". According to the README file it said that this column can store gateways "capabilities". For example, and I hope that someone could guide me here, can i store the maximum channels available per gateway?, and use it to select or not select a gateway according the gateway channels used?. I hope that someone could help me here. Thank in advance, Regards, Ricardo Martinez.-
