alias problem
by Stoyan Mihaylov 30 Jan '12

30 Jan '12

My whole configuration is: [Sip clients] < = > Kamailio 3.2 <=> Asterisk servers (behind Kamailio) Asterisk servers have only local IP addresses, and I use t_relay instead of forward. Kamailio runs on same server as rtpproxy. Everything is fine if clients connect to Kamailio with its IP address - global, or if they are behind Kamailio with local address. When clients connect to Kamailio using sip.ourcompany.com, then call (video also) is OK, but ACK and BYE do not work. BYE receives not here (404), and ACK die somewhere. I forward BYE and ACK in case when src_ip==$td to Asterisk server. If one of clients use IP - then calls initiated from it are OK (BYE/ACK - are going correctly - to Asterisk and to other client also). But calls from other client have problems with BYE and ACK. To use sip.ourcompany.com - I put: alias=sip.ourcompany.com route[ACKBYE] { #!ifdef WITH_PSTN if (is_method("BYE|ACK")) { xlog("L_ALERT","AB $rm $sht(forw=>$ft) $td"); if(src_ip==$td){ #I have to rewrite du - messages loop in Kamailio, I store in $sht(forw=>$ft) $du which I use during INVITE. $du=$sht(forw=>$ft); route(RELAY); exit; } xlog("L_ALERT","ACK,Bye Not me"); } #!endif return; }

exec_avp size limitation
by Gustavo Garcia Bernardo 30 Jan '12

30 Jan '12

Hi folks, I'm having problems with exec_avp because is truncating the output of the script executed. Looking at the code I see exec_avp is imposing a limit of MAX_URI_SIZE (1024) but I don't understand why. The limit should be the maximum size for an avp variable in my opinion. Regards, G.

memory leak fix on xcap_ auth.c
by laura testi 30 Jan '12

30 Jan '12

Hi Daniel, I'm sending you some memory leak fix we have found and fixed on modules/utils/xcap_ auth.c. The fixed memory leak is in pres_watcher_allowed (), and it is about the "xmlFreeDoc" that it's never called for the "xcap_tree" variable. We downloaded the source file from master branch and then we fixed it. You can find here the diff from original and new code and in attach both the original and the new files. diff -u a/modules/utils/xcap_auth.c b/modules/utils/xcap_auth.c --- a/modules/utils/xcap_auth.c +++ b/modules/utils/xcap_auth.c @@ -280,13 +280,15 @@ } node= get_rule_node(subs, xcap_tree); - if (node== NULL) + if (node== NULL){ + xmlFreeDoc(xcap_tree); return 0; - + } /* process actions */ actions_node = xmlNodeGetChildByName(node, "actions"); if (actions_node == NULL) { LM_DBG("actions_node NULL\n"); + xmlFreeDoc(xcap_tree); return 0; } LM_DBG("actions_node->name= %s\n", actions_node->name); @@ -294,6 +296,7 @@ sub_handling_node = xmlNodeGetChildByName(actions_node, "sub-handling"); if (sub_handling_node== NULL) { LM_DBG("sub_handling_node NULL\n"); + xmlFreeDoc(xcap_tree); return 0; } sub_handling = (char*)xmlNodeGetContent(sub_handling_node); @@ -302,6 +305,7 @@ if (sub_handling == NULL) { LM_ERR("Couldn't get sub-handling content\n"); + xmlFreeDoc(xcap_tree); return -1; } if (strncmp((char*)sub_handling, "block", 5) == 0) { @@ -325,10 +329,12 @@ else { LM_ERR("unknown subscription handling action\n"); xmlFree(sub_handling); + xmlFreeDoc(xcap_tree); return -1; } xmlFree(sub_handling); + xmlFreeDoc(xcap_tree); return 0; Kind Regards, laura

Kamailio TLS with intermediate CA certificates
by Daniel Pocock 30 Jan '12

30 Jan '12

I found that my TLS client was not happy because my server cert is signed by an intermediate root. A quick search in Google found other people mentioning the same problem, but no solution or documentation. I've had a quick look in the Kamailio source and I notice it is using the call: SSL_CTX_use_certificate_chain_file to load the certificate specified in tls.cfg with certificate=myserver.pem In practice, this means the intermediate certificates can be appended to myserver.pem and Kamailio will present them to the TLS client: Example: Trust heirarchy: trusted root - inter 1 - inter 2 - server.example.com.pem Construct the PEM file in this exact order: cat server.example.com.pem > chain-server.example.com.pem cat inter2.pem >> chain-server.example.com.pem cat inter1.pem >> chain-server.example.com.pem and then, in tls.cfg: certificate=chain-server.example.com.pem

Kamailio for NATted users with ICE and TURN
by Daniel Pocock 30 Jan '12

30 Jan '12

There are now a number of TURN implementations available: http://www.resiprocate.org/ReTurn_Overview http://turnserver.sourceforge.net/ and for many purposes TURN relays and ICE are much better than relying on NAT helper and rtpproxy When clients use ICE: - the client gets upset if Kamailio mangles the SDP to use rtpproxy - it is actually not necessary for the SDP to have addresses tweaked - because ICE deals with it anyway In practice, it still appears necessary for the registration server to deal with NATted contact addresses though Can anyone clarify how Kamailio should be configured for ICE clients? In other words, is it possible to have Kamailio dealing with NATted contact addresses, but not touching the SDP? To limit the scope of the question: - assume non-ICE clients do not need to be supported at all (just ignore them, although a nice cfg would scan all SDP and send a helpful error back if it sees a 192.168 address and no a=ice* attributes) - assume clients are connecting with TLS over TCP, so there is no risk that some intermediate device like a router is mangling the SIP headers or SDP

Hello, the repositories with build RPMs done via OpenSUSE Build Services (OBS) were updated. Fedora 14 is no longer offered by OBS, instead I added support for Fedora 15 and 16. Also, there are now dedicated builds for RedHat 6 and OpenSUSE 12.1. Links to repos are provided at: * http://www.kamailio.org/wiki/packages/rpms Cheers, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com http://linkedin.com/in/miconda -- http://twitter.com/miconda

save a Q850 cause reason from a reply
by Uri Shacked 30 Jan '12

30 Jan '12

Hi, the gateway i use for sending call to pstn has an option of sending a header with Q850 reason. it looks like this: " Reason: Q.850;cause=17;text="UserBusy" Reason Protocols: Q.850 Cause: 17(0x11)[User busy] " now, i need to save the reason for reports. the reason changes and i am trying to find a way to parse it and save the code only. usualy i use the "search" function to get text from headers that are the gateway's inventions :-) here i can find the text "Q850....." but how do i get the cause code? i guess i cab write something long with textops and parsing. but, is there a better and nicer way to perform it? thanks, Uri
