Merging nathelper modules
by Ovidiu Sas 10 Feb '11

10 Feb '11

Hello all, The nathelper module in modules_k was split in two: - nathelper (dealing with signaling); - rtpproxy (dealing with rtpproxy protocol). I would like to move the rtpproxy module from "modules_k" into "modules" and remove rtpproxy functionality from nathelper (s). This will give to (s) and (k) users: - rtpproxy: a single module for dealing with rtpproxy servers; - nathelper: two variants for dealing with NAT signaling. Next step, will be to merge the two nathelper modules into a single one. Thoughts? Regards, Ovidiu Sas

nathelper-module and sdp offer in 200 OK
by Emil Kroymann 10 Feb '11

10 Feb '11

Hi, We recently had a problem with the nathelper module and rtpproxy in a scenario where the SDP offer is sent only in the 200 OK. We use sip-router 3.1 and rtp-proxy from git master. The sip-router configuration uses the rtpproxy_offer() and rtpproxy_answer() functions in appropriate places. The problem is, that the arguments sent to the rtpproxy, when the ACK with the sdp answer arrives, seems to be not in the order, that rtpproxy expects. On the 200 OK, the nathelper module sends callid, to-tag, from-tag to rtpproxy. On the ACK, the nathelper module sends callid, from-tag, to-tag (with different command prefixes, of course, but I cannot remember them atm). The version of rtpproxy that we are using seems to expect, that the order of arguments sent on the ACK request is the same as on the 200 OK. My question: are there any module parameters, to correct this behaviour?

Use different certificate for different client with TLS
by Daniel GROTTI 09 Feb '11

09 Feb '11

Hi all, I would like to use kamailio 3.1 with TLS and verified also a client certificate. My tls.cfg file is as follow: --- tls.cfg ---- ..... ..... [server:MY_IP:5061] method = TLSv1 verify_certificate = yes require_certificate = yes private_key = default_key.pem certificate = default_cert.pem ca_list = default_ca.pem [client:default] verify_certificate = no require_certificate = no .... .... So I want to verify the client certificate, to do that I use "is_peer_verified()" function in kamailio.cfg. As tls.cfg shows, I have to send to my clients the CA certificate and the client certificate (default_cert.pem + default_key.pem - signing by the CAcert). This client certificate is unique for all clients. Everything works fine. But suppose I wanted to create a client certificate for client 1 (cert_1.crt), and a different client certificate for client 2 (cert_2.crt) and I want to configure kamailio to be able to verified this different certificates. Does it possible ? How can I configure the tls.cfg file to do that ? I try to do something like this: [server:MY_IP:5061] method = TLSv1 verify_certificate = yes require_certificate = yes private_key = default_key_1.pem certificate = default_cert_1.pem private_key = default_key_2.pem certificate = default_cert_2.pem ca_list = default_ca.pem But when kamailio restart it seems that it read only the last couple of row certifcate/private_key.

[OpenSER-Users] uaCSTA support in openser
by Hugo Koblmueller 09 Feb '11

09 Feb '11

high.all! i'm wondering if there is any support of uaCSTA in openser (planned)? i'm just working on the integration of asterisk (*) environment to OCS 2007 environment, having openSER in the middle (mainly for TCP/UDP translation and smoothing out the protocol deficienes on both sides). in this setup the * having the openSER in front is talking to the OCS (and vice versa) via the OCS mediation server, which is moreorless sending standard SIP messages, which enables normal softphone (integration to *) of the office communicator. this configuration is already working... now i'm planning to go for the CTI integration, where there is no OCS mediation server in between OCS and openSER, doing the translation of SIP/CSTA to SIP. i'm thinking about using openSER for this task, that's why i'm looking for a CSTA module or perl programm, which is capable of this functionality. afaik for the CTI communication there isn't the full complexity of CSTA needed, just a subset mainly for call setup and call clearing. anyone having experience on this topic? thx & cheers -hugo Great Ideas for Small Devices Hugo Koblmueller Senior Staff Engineer Software Development COMNEON electronic technology GmbH & Co.

module postgres SER
by Bruno Bresciani 09 Feb '11

09 Feb '11

Hi, I've seen the problem in a postgres module (SER-0.8.1.4), if the connection fails and module tries to reparse url it fails as CON_SQLURL(_h) is corrupted by the function aug_free() after some reconnect attempts . When the postgres database back to work, some modules doesn't get reconnect because the db_url is corrupted. Why this is happening? There are some solution for this problem? Best Regard

Fosdem2011 presentation: SIP Web20 Lua
by Daniel-Constantin Mierla 09 Feb '11

09 Feb '11

Hello, the presentation I did during Fosdem in Brussels last weekend is available at: http://www.kamailio.org/events/2011-fosdem/dcm-sip-web-lua.pdf The focus was to show how to interact with Kamailio via HTTP and how Kamailio can interact with Web services via HTTP, using Lua to make it easier. There are slides for a demo config of sending asynchronous notifications to Twitter on missed calls (using modules app_lua, mqueue, sqlops and rtimer). Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com
