[Serusers] CNAM in SER
by Brian Artigas 13 Nov '09

13 Nov '09

Hello, Our VoIP provider doesn't provide CNAM to us so we have to access an outside provider for this. Can anyone point me in the right direction for running an http request and passing the result back out so the pbx can pick grab the callerid. I know that OpenSER they has the Utils module but SER doesn't have that. Any ideas? Thanks in advance, Brian Artigas Allstate Computers, LLC brian(a)allstatecomputers.com www.allstatecomputers.com P: 561.743.1521 F: 561.575.9234

[Kamailio-Users] Remote management and security
by Brian 13 Nov '09

13 Nov '09

Hi, Does anyone know how I can do remote management of Kamailio in a secure way? Looking at the documentation for MI_DATAGRAM and MI_XMLRPC, there does not seem to be a way to authenticate the request, or a way to restrict requests to specific IP ranges. I want to be able to send management commands remotely, but I don't to make this wide open. Thanks, Brian.

[Kamailio-Users] SKYPE or voipstunt
by Masoom Alam 13 Nov '09

13 Nov '09

whether skype or voipstunt are using SIP protocols. I have experienced that in many countries, where voice ports are blocked by the Telecom providers but still voipstunt and skype works for calling to PSTN. Please give me some links, for further reading on this.

[Kamailio-Users] Register Request Forward
by toqeer ali 12 Nov '09

12 Nov '09

Hi all, My question is how to forward Register Request to another sip server. For example one user (X-lite) want to register with 192.168.0.1(sip server1) via 192.168.0.2(sip server 2). it means that in the domain part of xlite is 192.168.0.2 and it basically register with 192.168.0.1. 192.168.0.2 will forward Register request to 192.168.0.1. it will be very helpful if any one can answer. Thanks -- Toqeer Ali Syed Red Hat Certified Engineer mob: +92 321 9059916

[Kamailio-Users] record-route
by toqeer ali 12 Nov '09

12 Nov '09

Let me describe my scenario: SipUser1 -------register request------------> kamailio (SIP Proxy) ------- forwarded register request-----------> Asterisk 1. In the above scenario, when I register to Asterisk through Kamailio, it works fine when I give the "record-route()" function in the cfg file. Further, using this, I can also call to another extension 602 which is also registered to Asterisk but 602 cannot call to 601 which is registered via kamailio. 2. However, If I remove the "record-route()" function without unregistering 601 and restarting the server, 602 can call to 601 . route { if ($fU=="601"&&is_method("INVITE")) record_route(); rewritehost("10.0.10.111"); //asterisk host route(1); } route[1] { # send it out now; use stateful forwarding as it works reliably # even for UDP2TCP if (!t_relay()) { sl_reply_error(); }; exit; } should i add anything in script further... -- Toqeer Ali Syed Red Hat Certified Engineer mob: +92 321 9059916

[Kamailio-Users] Listening on more than one port
by Sven Schulz 12 Nov '09

12 Nov '09

Is it possible to have kamailio (1.4.4) to listen on more than one port? Is it as simple as adding another ³port=xxxx² in the config? Sven Schulz Penn State University Telecommunications and Network Services 814.865.6116 sip:sven@psu.edu

[Kamailio-Users] sending calls to voip provider
by Andres Moya 11 Nov '09

11 Nov '09

Hi, I am with openser about my first 40 hours. So far i managed to install 3.0. Was able to make calls between registered phones. Enabled accounting, etc. Looks i have control ;) Now i have a very simple question. I want to send calls for land lines via voip provider, sipdiscount.com in my case. I want to enable so registered client agent can send invite to that server, but it should re authenticate somehow. I was looking for proxy_authorize www_authorize but it looks like it authenticate my phones only. I was trying rewrite rewritehostport, but of course was getting authentications errors. Is there any manual, previous discussion on this topic? Thank you.
