Re: [Serusers] serial forking with a recursive failure_route block
by Jiri Kuthan 14 Jul '04

A possibility to keep status would be to use flags -- a poor variable substitute till support for variables appears. -jiri At 10:14 PM 7/13/2004, Michael Przybylski wrote: >Hello everyone, > > I've got a recursing failure_route block that I'm trying to use >for voice over IP gateway failover. > The recursion bit works without any problem, but I could really >use some hints on examining the branches appended by previous calls to the >failure route so that it can know when to stop. > > Here's the pseudo-code version of what I'm trying to do. > >if(examing previously appended branches shows > IP of last-chance gateway already there){ > give up; >} > > Any suggestions would be greatly appreciated. > >Best regards, >Mike Przybylski > >_______________________________________________ >Serusers mailing list >serusers(a)lists.iptel.org >http://lists.iptel.org/mailman/listinfo/serusers -- Jiri Kuthan http://iptel.org/~jiri/

[Serusers] quiting immediately
by Cyprien Simons 14 Jul '04

14 Jul '04

Hi everybody, I got a problem with launching ser. It launch correctly, but quit immediately without prompting an error message. I took a look in the /var/log/messages file and there is what I found: ser: INFO: SIGCHLD received: we do not worry about grand-children ser: DEBUG: tm_shutdown: releasing timers ser: DEBUG: tm_shutdown : removing semaphores ser: DEBUG: tm_shutdown : done ser: shm_mem_destroy ser: destroying the shared memory lock This computer is running SuSE 9.1 with ser 0.8.12 and this problem wasn't there last week. It just appeared today. Since I'm not the only one working on this computer, something could have been modified, but I'm wondering what... Cyprien

[Serusers] Remote Party ID
by Charles Galea 14 Jul '04

14 Jul '04

We have downloaded the latest ser software from cvs in order to support appending of remote party id while using mysql as the ser database. After compiling and installing the ser software we included the auth and auth_db parameters and also the append_rpid_hf() function in our ser.cfg file as shown below. SER server starts and registration is successfull however when forwarding to the pstn gateway, ser will not append the remote party id header, even if the rpid and uri columns in mysql database are populated accordingly using the serctl add rpid command. Calls are also successfull however the gateway will not include the calling party number in the setup message because the rpid header is missing. Any ideas please?

I'm afraid not, because I'm _really_ a newbie on SER. I just get the old configuration file from the guy who was working on my project before, and i'm trying to understand it. Don't ask me to write one, I can't...

[Serusers] dialing rules in ser.cfg + voicemail
by Shaharyar Awan 14 Jul '04

14 Jul '04

I have two questions: 1. Is there a way I can add some dialing rules and other configuration items through the database? I think editing the cfg file can be very cumbersome. 2. Is no other way to have voicemail and stuff except using SEMS? Can someone please send me a working cfg file with mysql database authentication, accounting and voicemail? Thanks. __________________________________ Do you Yahoo!? Yahoo! Mail Address AutoComplete - You start. We finish. http://promotions.yahoo.com/new_mail
