Try to increase PKG_MEM_POOL_SIZE in config.h. Its default value is 1MB and all ser local (per process, not shared) memory allocations cannot exceed it. Andrei

[Serusers] web-based SIP request generator
by Klaus Darilion 11 Feb '04

Hi! I have written a small php script, which sends SIP requests and displays the responses. http://obelix.ict.tuwien.ac.at/sip-gen/sip-request-gen.php It's far away from finished (->todo.txt). Feel free to use it or download the source http://obelix.ict.tuwien.ac.at/sip-gen/sip-gen.zip and add new functionality or bug fixes :-) Regards, Klaus

[Serusers] QOS in ser
by Annie Sasidar 11 Feb '04

11 Feb '04

Hi, I dont know if this is already present or even if it is valid. SER is a router so is there a way that voice packets get priorty over other packets between the two devices that are registered on the SIP server? I know that the SIP server does not work with the RTP packet but when a user is trying to invite a new user for a conversation is there a way for ser to determine whether the network available at that time will allow the voice packets to reach destination without distortion. Would like to know your insight on this. Thanks, Annie

[Serusers] I'm not able to connect to SER with Windows Messenger
by Miroslav Sycha 10 Feb '04

10 Feb '04

Hello all, Our customer wants to use Windows messenger for his staff. We don't want to use Microsoft server so we decided to try SER. I have installed SER 0.8.12 from deb package on Linux (Debian Woody 2.4.18). But I'm SER beginner and I'm not able to login to server with Windows Messenger 5.0 I always got timeout at the end. Here is start and the end of dump from ngrep. # U 10.1.22.235:1655 -> 10.1.22.237:5060 REGISTER sip:email.cz SIP/2.0..Via: SIP/2.0/UDP 10.1.22.235:9868..Max-Forwa rds: 70..From: <sip:msy@email.cz>;tag=cef1e2e367de4afe826adbda2eff8952;epid =be8270f04c..To: <sip:msy@email.cz>..Call-ID: a73f0f8743274cb09fe02d0a4cfee 6a0@10.1.22.235..CSeq: 1 REGISTER..Contact: <sip:10.1.22.235:9868>;methods= "INVITE, MESSAGE, INFO, SUBSCRIBE, OPTIONS, BYE, CANCEL, NOTIFY, ACK, REFER "..User-Agent: RTC/1.2.4949 (Messenger 5.0.0468)..Event: registration..Allo w-Events: presence..Content-Length: 0.... # U 10.1.22.237:5060 -> 62.168.57.98:5060 REGISTER sip:email.cz SIP/2.0..Record-Route: <sip:10.1.22.237;ftag=cef1e2e3 67de4afe826adbda2eff8952;lr=on>..Via: SIP/2.0/UDP 10.1.22.237;branch=z9hG4b Ka645.750257f2.0..Via: SIP/2.0/UDP 10.1.22.235:9868..Max-Forwards: 69..From : <sip:msy@email.cz>;tag=cef1e2e367de4afe826adbda2eff8952;epid=be8270f04c..

Can someone give me any simple example how to configure SER for Win messenger client? I would like try older Windows Messanger version but I'm not able to find it on the web.

RE: [Serusers] CPL tags problem

Hi Bogdan, Yes, we get the errors when uploading the script. See the script file we are trying to upload (using cpled)in attach. Thanks, Toni -----Original Message----- From: Bogdan-Andrei IANCU [mailto:iancu@fokus.fraunhofer.de] Sent: terça-feira, 10 de Fevereiro de 2004 17:22 To: Toni Barata Cc: serusers(a)lists.iptel.org Subject: Re: [Serusers] CPL tags problem Hi Toni, "otherwise" is a subtag of a multiple tag, like address-switch, language-switch, and other switch nodes. Both the otherwise subtag and lookup tag where successfully used. Do you get error when uploading the script or when running it? Some output will be very useful to trace down your problem. Use debug=9 into your config script to enable full debug.
