[Kamailio-Users] mk_proxy: could not resolve hostname
by kévin l'heveder 14 Jan '10

14 Jan '10

Hi, I'm using kamailio V3.0 In the kamailio.cfg when I use the "send" function with an IP inside (as send("127.0.01:51001"), I see the following error : mk_proxy: could not resolve hostname: "127.0.01:51001" At first, kamailio was sending request to the DNS server which define in resolv.conf to resolve "127.0.01:51001" The DNS could not resolve this name then the error occured So I removed this defined DNS and now no request are sending but still have the same error. I tried to set dns and use_dns_search_list parameters to no, but that's change nothing Anybody have any ideas? Regards, Koon

[Serusers] ser scalability
by Sabatella, Michael 14 Jan '10

14 Jan '10

I just wanted to run this by the group. I did a complete overhaul on one of my ser environments and upgraded the physical server and all software around my sip proxies. I am also maintaining a complete front end for provisioning and billing that I also moved(PHP/mysql) I am running this on a Virtual machine (vmware esxi). If I need more proxies I can clone the VM and build in new service/capacity pretty fast. I am running 0.9.6 on Redhat ES 5. I have 4 cores dedicated to this server running Xeon 2.93GHz processers and 4 GIG memory. I am running the 32 bit OS. I hardly see the processor tick up to 1%. The machine I am testing has about 300 registered endpoints in the proxy db. My questions are: 1. What is the scalability of ser processing calls? 2. Are there any limits on the number of users that can be registered at one time. Is the registration memory based and am I severely limited with 4GB of memory? 3. Is there anyone that has 1000s of registration to the proxy and if so I would like to hear how you are scaling it. What type of server are you using? 4. What are some good metrics to look at on the sip proxy to gauge its performance? 5. Is there a way to capture calls per minute? Is anyone doing this? I have call accounting set up.

When I implemented in in old kamailio, it was no option for me than using kamailio-to-kamailio SCTP channel. Cheers, Daniel -- Daniel-Constantin Mierla * http://www.asipto.com/

[Kamailio-Users] Rtpproxy not recording media stream
by Vikram Ragukumar 13 Jan '10

13 Jan '10

Hello, I have setup Kamailio(v1.5) and Rtpproxy(v1.2.1) on a Centos5.4 linux box. Kamailio's config file has been edited to include Nat and mysql support. With Kamailio running, i started rtpproxy using rtpproxy -l ip_addrs -s udp:127.0.0.1:7722 -a -r /var/log -F However rtpproxy does not seem to be recording any session. I read that the -a switch can be used to record all sessions. Am i missing a switch/doing something wrong while invoking rtpproxy ? Regards, Vikram.

[Kamailio-Users] SIP proxy is expecting "Route:" header to be filled information from the last "Contact:" header ?
by Julien Chavanton 13 Jan '10

13 Jan '10

Hi all, first thank you for maintaining this list and free/Open source SIP proxy software. I am working on one interco problem with a remote SIP proxy running on Kamailio. Cisco(U1) --> Opensips(P1) --> Internet --> Kamailio(P2) --> Asterisk(U2) The remote proxy(P2) is expecting us to fill the "Route:" header taking information from the "Contact:" header, according to my research the "Route:" header as to be filled using the information found in the last "Record-route:" header. Note that the "Contact:" header IP address is the one of U2, as it is the destination UA. I think our partner using Kalamailio only interconnected UA not Proxy, since they never faced this problem. Of course I do not suspect Kalamailio to be doing something wrong, I just want to validate what we should expect, and investigate further from there. I will have to contact the technicien that as configured the Kalamailio server to validate why face this behavior. -------------------------------------------------------------------------- " 16.12.1.3 Rewriting Record-Route Header Field Values " http://www.ietf.org/rfc/rfc3261.txt -------------------------------------------------------------------------- We found a temporary solution to make it worko, where we hardcoded the replacement of the IP address in the "Route:" header with the one of the U2 subst('/^Route: <sip:P2;(.*)$/Route: <sip:U2;\1/');
