AVP Error in version 3.1.0
by Jijo 21 Feb '11

21 Feb '11

Hi All, On register we store the contact in an avp variable and do a t_relay(). After t_relay() the $avp variable becomes null. I printed the value before after t_relay() to determine this behavior. This happens only on registration load test around 2000 subcribers with ( 4 REGISTER/sec). This happens only for one subscriber out of 2000 subscribers. I did the similar test with $var and its working fine. Anybody observed similar behavior with avp? This was working in kamailio 1.4 version. We did the upgrade recently to 3.1.0 and started observing this issue. How do we debug this issue.? Thanks Jijo

pcre mystery or bug in dialplan module?
by Juha Heinanen 21 Feb '11

21 Feb '11

i have in dialplan table record 287 14 10 1 ^(.+)\+358 0 ^(.+):\+358(.+) \1:0\2 and when it is applied to uri Feb 21 08:05:15 sip /usr/sbin/sip-proxy[24071]: INFO: uri <sip:+35892345670@test.fi;user=phone> the resulting uri looks like this: Feb 21 08:05:15 sip /usr/sbin/sip-proxy[24071]: INFO: uri <sip\1:092345670@test.fi;user=phone> i can't figure out, where \1 comes to the result, because \1 is has already produced 'sip' to it. i have added debug to dialplan module and looks like it compiles correct subst and repl expressions: Feb 21 08:05:05 sip /usr/sbin/sip-proxy[24067]: INFO: dialplan [dp_db.c:392]: parsing repl_exp <\1:0\2> Feb 21 08:05:05 sip /usr/sbin/sip-proxy[24067]: INFO: dialplan [dp_db.c:404]: compilig subst_exp <^(.+):\+358(.+)> is there some stupid mistake in the expressions or could it be a bug somewhere? -- juha

Failure Route and Reply Routes
by Brandon Armstead 19 Feb '11

19 Feb '11

Hello, Is there any specific information / documentation as to what kind of response causes the failure_route to trigger over the reply_route. For example, it seems that 486 response triggers the failure route while as a 408 triggers the reply_route. Perhaps I am over looking something? I would imagine that 5xx and 6xx (final / non provisional responses) would trigger the failure route. While as 4xx would trigger the reply route -- however this does not always seem to be the case in the example of 486 vs 408. Any information / help in advance is greatly appreciated, thanks! Sincerely, Brandon Armstead

Kamailio NOTIFY
by Spinov Evgeniy 19 Feb '11

19 Feb '11

Hello all. I'm having problem with sending NOTIFY packet for event dialog. The problem is, that all NOTIFY packets sent with this event is empty. ( Content-length: 0 ) and in fact, not passing actual status to the phone. In my case this is SPA962. NOTIFY packets for event presence are sent fine and status is changing normally. The same phone, works fine with Asterisk. Asterisk is sending NOTIFY with non-zero content and changing status for the subscriber as well. I've turned on pua module to send PUBLISH requests at Kamailio, it's filling DB table with subscription, everything runs fine and NOTIFY packets are coming to subscribed phone, but they are empty. I also have presence_dialoginfo module on and pua_dialoginfo module on. I've tried on Kamailio 3.0.3 and 3.1.1. Content always empty. There is no sense of pasting here packet dumps, cause everything is like should be: (UAC) SUBSCRIBE, event: presence ---> K K ---> 202 OK (SPA) SUBSCRIBE, event: dialog ---> K K ---> 202 OK PUBLISH, event: presence ---> K K ---> 200 OK NOTIFY, event: presence, Content-Length: XXX ---> UAC NOTIFY, event: dialog, Content-Length: 0 ---> SPA962 As result, softphone changes status and hardphone ( SPA962 ) - no. May be it's cause of PUBLISH event value? Please advise.
