[Serusers] rtpproxy and IPv6/IPv4 translator
by CURRO_DOMINGUEZ 23 Jun '04

23 Jun '04

Hello I've been installed last version of SER and rtpproxy on the same machine. I can register IPv4 and IPv6 users and SDP are rewritten OK. But I would like to test a different scenario and I don't know whether it could be possible. The idea is IPv6 only SIP proxy IPv4 only SIP Proxy with nathelper SIP Proxy and registrar ---------- and rtpproxy -------------and registrar ipv6mydomain.com ipv4mydomain.com I want to separate functions and make config files easier. And I want that all the calls between the two domains are through the rtpproxy. But it presents several problems, at least, I don't find solution - When ipv6-SER DNS lookups ipv4mydomain, it will find an A entry with IPv4 address. How can I specify to forward messages to intermediate proxy in this case? In other words, if DNS domain==ipv4 then forward to intermediate proxy - Proxy with nathelper does not register users. So it just have to: - if message is ipv6 --> if (af == inet6) if (force_rtp_proxy("FAEI")) t_on_reply("1"); - if message is ipv4 --> if (af == inet) if (force_rtp_proxy("FAIE")) t_on_reply("1"); Is it correct?. Well, maybe could be another questions that I no see. I would thank if you could give me your opinion. Is there any problem to do this scenario? What things should I take into account? Could you give me some clues to write config files? Thank you very much. Curro

[Serusers] Accounting and MySQL
by Bill 23 Jun '04

23 Jun '04

I am trying to understand the logging with the accounting module. I don't understand the concept used with the flags. I'm trying to use the MySQL for logging completed and failed calls. I can get entries like log(1,"register request for domain"); to log something to syslog but I can't get a successfull call logged into the MySQL tables. So far I've been doing trial and error and haven't had any success. Can someone send me a simple config demostrating the concept of the flags or explain it to me please? I'm using ser 0.8.12 with MySQL 4.0 Bill Dunn

[Serusers] Need Help
by Vanita Jain 23 Jun '04

23 Jun '04

Dear Sir, I am new to SER. Can I modify the code and run it as per my need? I am working on a SIP application and need to test it with a server which will understand my modified SIP Message. This SIP message will have some specific Parameters. So can I modify registrar code to work as per my need? Rgds- Vanita Jain

[Serusers] [NAT] How to force both local client to make call not via rtpproxy ?

[Serusers] Problem with TCP/UDP translation
by Daniel Machín Vazquez-Illá 22 Jun '04

22 Jun '04

Hello I have a problem when two clients (one using UDP and one using TCP) connect to SER (version 0.8.13-dev-23). My scenario is more or less like this: TCP Client <----> SER <----> UDP Client There are no NATs or Firewalls in scene. I want to reuse the TCP connection of the TCP Client for the whole SIP signalling, so I have added the command force_tcp_alias(); to ser.cfg and changed tcp_conn.h as advised in http://lists.iptel.org/pipermail/serusers/2004-May/008262.html. The TCP Client starts the call with an INVITE and everything works correctly. However, when the UDP Client tries to send a MESSAGE, SER doesn't route the MESSAGE through the TCP connection (it sends it over UDP with the TCP port included in TCP Clients Contact!). Can anyone tell me what is misconfigured? Lots of thanks to everyone. DANIEL
