Issue loading ims_dialog module
by Vikram Chhibber 01 Jul '16

01 Jul '16

Hi All, I am trying to bring-up PCSCF on releae 4.4 and I am getting errors related to loading of ims_dialog module. The mpath is set correctly in kamailio.cfg and ims_dialog.so is present in that path. Interestingly, it is able to load rest of the modules from the same locaiton. ls -lrt /usr/local/lib64/kamailio/modules/ims_dialog.so -rwxr-xr-x 1 root root 953760 Jun 29 16:37 /usr/local/lib64/kamailio/modules/ims_dialog.so Any pointers will be appreciated. -- Unit kamailio.service has begun starting up.

Dialplan module doubt
by José Seabra 01 Jul '16

01 Jul '16

Hello there, I'm evaluating if I can use dial-plan and dispatcher module to build a kamailio routing server to route calls based on number dialed(sometimes the number dialed can be Alphanumeric). I'm expecting have lot of dial-plan entries, some of them with manipulations, others without. Anyone can see here any limitation on this implementation? One thing that I have noticed is that dial-plan module enforces me to fill the fields substr_exp and repl_exp even if i don't have any manipulations to apply. I'm also concerning about performance issues with lot of dialplan entries. What are your thoughts about this solution? Thank you -- José Seabra

ACK / BYE transaction problem
by Oliver Roth 01 Jul '16

01 Jul '16

Hi all Follow scenario Class5 system [c5] --> Loadbalancer kamailio (dispatcher module) [lbl] ---> gateway kamailio [gw] --> carrier [carr] I get Invites from [c5] with Request ,To, from, contact, pid in national format 0794445566 [lbl] dispatches this to [gw] For the [carr] I need international format. So doing these transactions in [gw] And sending to [carr] in international format Request, to, from, contact, ... => 417794445566 Everything ok Then I get a 100, 183 and even 200 from [carr] Ack is coming from [c5] to [lbl] and [gw] - but then it stocks The ACK is not sent to the [carr] I kamailio log I see DEBUG: RFC3261 transaction matching failed DEBUG: t_lookup_request: no transaction found So for me, the ACK cannot be assigned to a transaction and gets discarded by if ( is_method("ACK") ) { xlog(,"L_INFO", "WITHINDLG ACK - not loose route\n"); if ( t_check_trans() ) { xlog(,"L_INFO", "WITHINDLG ACK - t_check_trans() \n"); # no loose-route, but stateful ACK; # must be an ACK after a 487 # or e.g. 404 from upstream server t_relay(); exit; } else { xlog(,"L_INFO", "WITHINDLG ACK - not t_check_trans() DISCARD!!\n"); # ACK without matching transaction ... ignore and discard route(NATMANAGE); #t_relay(); #exit; Any idea? Problem with modifying the sip tags? Or problem with the dialog? Thanks for helping OIi

Kamailio Iterate All Headers
by Colin Morelli 01 Jul '16

01 Jul '16

Hey all, Back with more questions. I'm using Kamailio to make an HTTP call to my API to perform authentication and message routing. Currently, I'm trying to build up the post body that I send to my API to make those decisions. I've cherry picked a few of the headers that are important in my routing decisions. But, ideally, I'd like to just iterate over all the SIP message headers and append them as request parameters to my API call. Is this possible with Kamailio? I've been looking through the docs and can't seem to find a function to iterate the full list of headers. Thanks in advance. Best, Colin

by Никита Лебедев 01 Jul '16

01 Jul '16

Good day! Can anyone point me to right direction? The question is - I want to get list of registered users (to find out who is online at the moment) from sip server. I'm using kamailio on server side and exosip library on client side. I tried to find something in RFC 3261 and failured... Can someone help and tell what to do or where to look for the answer?

Kamailio Load Balancer Architecture
by Daryn Johnson 30 Jun '16

30 Jun '16

I am interested in opinions and suggestions about load balancing with Kamailio. I work for an ITSP that currently uses Oracle & Broadsoft, and I am working to design and develop an open source solution using Kamailio (Proxy, Registrar, LB) & other Application/Media servers for more flexibility and freedom :) Thank you ALL for the work you have put in on Kamailio! After much reading and configuration I have a Kamailio 'proxy' setup, with endpoints registered using the Registrar module, and calls being sent/received to/from the PSTN. I am interested in separating the Load Balancers from the Registrars & logic, for security and in order to be able to scale appropriately. I will be using the dispatcher module for both load balancers and proxies using the following architecture: PublicIP = 5.5.5.5; Private IP = 192.168.1.0/24 USERS (Public Internet) ==> (public: 5.5.5.5) [ Kamailio (LoadBalancer, Firewall, Sanity Checks) ] (core:192.168.1.2) ==> [ Kamailio Registrar, Proxy, PSTN GW ] ==> AppServers or PSTN GW (we can access our PSTN gateways Via our Core using Private IPs) Questions: 1) Is it overkill to separate the LB & Proxy/Registrars? 2) Is this a common architecture & anyone configured this architecture successfully? Thanks in advance for your help! *Daryn Johnson* *Senior VoIP Engineer*
