ims_charging module - AVP's
by Shane Harrison 18 Feb '15

18 Feb '15

Hi IMS'ers I am generating CCR's happily from the ims_charging module (adapted to work standalone with standard userloc module) but have a couple of questions around AVP's supported. a) I note that in the 3GPP TS 32.299 V12.7.0 specification that table 7.1.0.1, that it indicates Vendor-Id and Vendor-Specific-Application-Id aren't used. But later in section 7.1.16 it indicates that the Vendor-Id should be 10415 and set inside the Vendor-Specific-Application-Id AVP. Should I assume that the table is wrong ? b) The ims_charging_module doesn't seem to put an Auth-Application-Id into the CCR. This is mandatory according to 3GPP and RFC4006. I note that it does appear under the Vendor-Specific-Application-Id - but this doesn't seem right to me? At this stage I am thinking to add the Auth-Application-Id AVP and also the 3GPP Called-Party-Address AVP. To I submit patches to the development list?

Credit Control modules
by Shane Harrison 18 Feb '15

18 Feb '15

Hi all, As you will have seen from my posts, I have adapted the ims_charging module to work with usrloc module i.e. outside ims environment. I am interested in whether others see a use in having a Diameter Credit Control module that is standalone. There are already a number of Credit Control modules other than the ims one e.g. cncxx and I am not sure if the community sees a need for YACC. If there is interest then need to consider further how best to approach accommodating both ims dependence and standalone operation.

rtpproxy bridge "ie" "ei" behind NAT (like in aws EC2)
by Giovanni Maruzzelli 17 Feb '15

17 Feb '15

dear Kamailians, I have Kamailio+rtpproxy in front of FreeSWITCH. Kamailio and FreeSWITCH are on the same private network. Public Internet IP address ports are redirected to Kamailio and rtpproxy (same situation as in Amazon EC2). Clients comes from Internet, and make calls to Internet, SIP signaling passing through FreeSWITCH (eg: A leg incoming INVITE, FreeSWITCH originate an outbound B leg INVITE, and then bridge the legs). Using rtpproxy with -A "advertise" patch from Daniel, this topology works fine in a "traditional" telco way: rtp goes from caller to rtpproxy to callee, and viceversa. Now I want to maintain FreeSWITCH in the middle of rtp flow all the time, in a pure b2bua way, so it can control and analyze the media streams. So, I need rtpproxy to act paying attention to direction, as in caller->rtpproxy->freeswitch->rtpproxy->callee (and viceversa). Normally I would use Kamailio multihomed and rtpproxy in bridging mode. But I cannot have a NIC on the public address. How I can use the "ie" "ei" feature of rtpproxy in an Amazon-EC2 like environment? (eg: no public address attached to machine, but ports redirection from public address). I read this trick from Hugh Waite: "I have used rtpproxy (with the advertised address patch) in Amazon to bridge media between internet facing and private subnets in a VPC. I found that I couldn’t use different advertised addresses depending on which direction the signalling was going on a single private IP address. I worked around this by allocating a second private ip address to the instance and used that in the ‘bridge’. -A 54.86.X.X/10.0.1.15 –l 10.0.1.10/10.0.1.15" Can you explain how to use this trick, or another way (without additional addresses is gladly accepted!) to reach the same result (rtp always passing through FreeSWITCH) ? Thank you all in advance, -giovanni -- Sincerely, Giovanni Maruzzelli Cell : +39-347-2665618

Session timers
by Eric Koome 17 Feb '15

17 Feb '15

How do I process session timers in Kamailio coming from particular upstream provider every 15mins during a call? At the moment the the call fails after 15 mins. Related to this, another provider sends re-invites during a dialog to check that my kamailio is alive. However Kamailio responds with "488 not here". How do I process these as well? Asterisk sits behind Kamailio. Thanks Eric

load balancing + rtpengine
by Virmantas Variakojis 17 Feb '15

17 Feb '15

Hi, I want to use load balancing (dispatcher or carrierroute) but i have two upstream interfaces (separate vlan's to provider sides) and third interface to SIP clients side. Also i need to rewrite sdp fields with correct information with rtpengine, but it's impossible as i don't know whitch direction (provider) will be chosen by algorithm. Is it possible to use load dispatcher or carrierroute in conjunction with rtpengine or load balancing must be done manualy? — Regards, Virmantas -- __________________________________________________________________________ CONFIDENTIALITY NOTICE: The information contained in the present message (including any information contained in attachments herein) may be confidential and privileged.

TLS certificates per domain
by Muhammad Shahzad 17 Feb '15

17 Feb '15

Hi, I want to deploy a kamailio v4.2.x setup with multiple domains, all resolve to same IPv4 address kamailio is listening on. I am bit confused about how to configure TLS certificates using tls config file as mentioned here, http://kamailio.org/docs/modules/4.2.x/modules/tls.html#tls.p.config The documentation states that, -- If set the TLS module will load a special config file or config files from config directory, in which different TLS parameters can be specified on a per role (server or client) and domain basis (*for now only IPs*). The corresponding module parameters will be ignored. -- since all domains resolve single IP, so i assume i can specify only one section in tls config file with pair of key/pem file path. How can i specify more server certificates for same ip but with different domains? Thank you.

Syntax issue?
by Igor Potjevlesch 17 Feb '15

17 Feb '15

Hello, I'm looking for a way to track a call by using basic AVP like this: Into a route that treats INVITE: $avp(s:state)="call_start"; Then, if I test this AVP into WITHINDLG route: if($avp(s:state)!="call_start") ; the test fails. Did I miss something? The goal is to update this AVP during the life of the transaction. Regards, Igor.

selective logging with debugger module
by Sharath Kumar 16 Feb '15

16 Feb '15

Hello, I followed the documentation from http://kamailio.org/docs/modules/4.2.x/modules/debugger.html#idp84752. I have the global debug flag at 9. modparam("debugger", "cfgtrace", 1) modparam("debugger", "mod_level_mode", 1) modparam("debugger", "mod_level", "core=3") My Kamailio complains with a parsing error of some sort and fails to start. - "dbg_mod_level_param(): cannot store parameter: core=3" My intention is to turn off/reduce the "core" module tracing while keeping the "script" module at debug. Any suggestions ? I am running version 4.1.4. thanks Sharath
