[Serusers] problem with instant messages
by Milivoje Mirovic 15 Jun '04

15 Jun '04

Hello everybody! I'm configuring sip server as my student project and I have few problems, so I'll appreciate your help: I have configured ser and serWeb, pstn gateway, mysql, everything is working fine. How I'm unable to put IM (instant messages) from serweb in function: - I have configured ser to accept messages in this way: ... fifo = "/tmp/ser_fifo" fifo_mode = 0777 ... loadmodule "/usr/lib/ser/modules/msilo.so" ... modparam("msilo", "registrar", "sip:registrar@rcub.bg.ac.yu") modparam("msilo", "db_url", "sql://ser:password@rcub.bg.ac.yu/ser") ... if (method == "REGISTER") { if (!save("location")) { sl_reply_error(); }; m_dump(); break; }; ... if (method == "MESSAGE") { if (!t_newtran()) { sl_reply_error(); break; }; if (m_store("0")) { t_reply("202", "Accepted for Later Delivery"); break; }; t_reply("503", "Service Unavailable"); break; }; Problem is that serweb continues to report '408 Request timed out' message. I think that maybe there is problem with fifo, but I'm not sure. I tried to run shell script for sending IM (from admin guide) but in syslog there were several errors, all saying that line must begin with ':' (for lines: NOTIFY, sip:originator@foo.bar etc.). Why script doesn't work? Can you help me solve the problem? Thank you in advance. Milivoje __________________________________ Do you Yahoo!? Friends. Fun. Try the all-new Yahoo!

hey folks can I make my forwarding or rewrite decisions based on the attributes I have in the request. I want to make the forwarding decision based on the user agent or the various SDP attributes that are there in the INVITE request. How can I read and compare all the information I find in the SIP protocol Like based on 1) User-Agent: Asterisk PBX 2) or based on the media type like text , voice , video Please if any one can help me and provide me with examples ..... thanks Dipen K Gala Fidelity Investments System Company - Telecom Phone: (617) 563-2729 Email: Dipen.Gala(a)FMR.com

RE: [Serusers] SER Configuration

Hi Harris, I recommend you read Ser HowTo document first, as this will help you get started fairly quickly. http://iptel.org/ser/doc/ser-howto/ser-Howto.html Regards, Freddy -----Original Message----- From: serusers-bounces(a)iptel.org [mailto:serusers-bounces@lists.iptel.org]On Behalf Of Harris Coltrain Sent: Monday, June 14, 2004 1:22 AM To: serusers(a)lists.iptel.org Subject: [Serusers] SER Configuration Hello, I am brand new to SER and need some assistance in setting up SER as a Proxy Server. The objectives are these. 1.) I need users to be able to register via authentication for one domain with SER via MSN Messenger. SJphone, Pingtel Etc. For user info I want to use the built in MySQL mod,and understand how to add users via "secrtl" but do not fully grasp the complete process to get the server to this point. If anyone could point me in the right direction, I would greatly appreciate it. Things that come to mind: What needs to be uncommented in the ser.cfg? What do I need to with DNS(i.e DNS_SRV records)? Do SER have an IRC#?
