Limiting concurrent calls
by Aft nix 15 Sep '12

15 Sep '12

Hi, I need to limit the number of concurrent calls go through kamailio. Its a simple set up(Not per user basis, a global limit will suffice). I know i need to employ dialog module. But i'm a little confused about profiles. I thought for simple application like this, i may be able to use profile altogether. Any code snippet to limit number of concurrent calls will be very helpful. Thanks in advance. -- -aft

[Kamailio-Users] Having problems using RTPProxy to bridge internal/external networks
by Joe Hart 15 Sep '12

15 Sep '12

Hi all, For a project on which I'm currently working, I am having some problems figuring out how to correctly configure Kamailio to communicate with RTP Proxy in order to send media into and out of a network with private IP address ranges. I have a proxy set up to send the SIP traffic, and all of this is working fine. However, I'm having some trouble getting the RTP Proxy set up. Currently, when the call is connected, the offer/answer is made and RTP Proxy seems to be taking over, but … [View More]

Howto add peers and routing rules
by Joel Smith | VOZELIA 15 Sep '12

15 Sep '12

Hi, I'm getting started with kamailio and siremis. I've just finished getting the server ready and the software installed. Once in the siremis admin menu, i've added a domian and a subscriber and I have my softphone registered with kamailio. My doubt is, where do I add peers so I can set up the routing rules? Are there any tutorials? Thanks in advanced. Best regards. -- Joel Smith Cell: +34 639 03 13 53 E-Mail: joel(a)vozelia.com <joel(a)vozelia.com> <http://www.vozelia.com> … [View More]
