[Users] Install on OpenBSD: cannot start openser
by Ben Ferguson - backcountry.com 22 Feb '07

22 Feb '07

Hello all, I've just installed openSER on OpenBSD and I'm now trying to get openSER to start and am having trouble. I try openserctl start and here's what i get: # openserctl start database engine 'MYSQL' loaded Control engine 'FIFO' loaded Starting OpenSER : \E[37;31mERROR: PID file /var/run/openser.pid does not exist -- OpenSER start failed # After a bunch of reading it seems as if openserctl is now obsolete (???) and that you should use the init script. I can't find reference for anyone running it like this on OpenBSD. I have found openser.init file in /<src directory>/packaging/gentoo and /<src directory>/packaging/rpm, but i am not sure how to use them on OpenBSD (I'm rather new to OpenBSD... I'm used to the rpm style of things.) I've searched and searched but can't find any info... So. anybody out there using openSER on OpenBSD? Or anybody know howto (or whereto find the info to) set up the start script for openSER on OpenBSD? Any help is greatly appreciated! Thanks, Ben

Hi ! Does someone know the maximum length of an Instant Message I can send with SER ? When I send an IM wich is longer, I get the message by SER : 2(9833) ERROR: read_line: request line too long 2(9833) ERROR: fifo_server: line expected 2(9833) ERROR: fifo_uac_error: body expected How can I solve this problem ? Can I set the maximum length of an IM in any file or something like that ? Best regards ___________________________________________________________ Der frühe Vogel fängt den Wurm.

[Users] Adding redirect support to my openser.cfg.
by Shane Burrell 22 Feb '07

22 Feb '07

I want to support 302 type moves. The sip devices we had before supported reinvites but the new linksys units send a 302 message telling me that the user has temporarly moved. Is there a good example of the redirects modules use in the cookbook example? My cfg file is based off that and I would like to add this to a live working system with little interruption or suprises. Thanks, Shane

[Users] maddr parameter
by Watkins, Bradley 22 Feb '07

22 Feb '07

I see that there was some discussion back in March 2006 (http://www.openser.org/pipermail/users/2006-March/003339.html) regarding this parameter, but nothing since. Daniel mentioned that perhaps it might be put on the to-do list, but I see no mention of it anywhere else. Was this implemented in 1.2? I see that maddr is available using pseudo-var transformations as {uri.maddr} in 1.2, but not mention of any automatic behavior if the parameter exists. I realize that I can work around it by using subst and subst_uri, but I really shouldn't have to. A simple t_relay should send it on its merry way to the value of maddr. My reading of both RFC3261 and 3263 seem to imply that the existence of this parameter in the request URI mandates forwarding the request to this address. I see in the code (for 1.1.1, I haven't looked at 1.2 yet) that the parameter is parsed, but then it appears (correct me if I'm wrong) as though nothing further is done with it. Is there some relatively simple way to modify the code to so that the maddr is used directly? As you can probably tell, I have a gateway with which I have to interoperate which uses this parameter extensively, hence my interest. :) Any advice (even if it's "use subst and subst_uri you whiner" ;) ) is appreciated.

[Users] Rewriting To: field
by Stéphane Alnet 21 Feb '07

21 Feb '07

Hello, I am doing interop testing with Level3, and need to be able to rewrite the To: field in requests to match their requirements. I can fake the rewrites inside route[], but although the packets sent out look like they use the new "To:", the header is never parsed again, so the internal structures of SER still hold the former (incorrect) value. When a request hit failure_route[] (for example when a CANCEL is sent when an INVITE times out) the original, incorrect To: header is then sent (and there's no way to modify the content of the CANCEL from within failure_route[]). Is there a standard way to alter the internally-stored value for To: (and From:, since I'm asking)? If not, could someone point me to the right place in the code to start adding this kind of feature? Thanks, Stéphane Alnet -- http://carrierclass.net/ http://www.linkedin.com/in/stephalnet
