Re: [OpenSIPS-Users] How to limit channel on bunch of called DIDs?
Hi Bogdan,
I was able to implement the channel limiting on one DID by using a variable
instead of AVP and replacing all instances of $tU to $rU. Now, I want to
limit the channels to a set of DIDs and I'm thinking of implementing a
while loop and counter in order to achieve it. Is this an efficient way
of doing the limiting on a set of DIDs? One problem I can think with the
while loop and counter will be how to deduct those calls that were
already hung up by the caller. Again, inputs will be greatly appreciated.
Thank you very much.

Hi
It is hard to review scripts to see where the problem is, but I will
help you with some hints on troubleshooting.
First of all you need to be sure you put in the profiles the calls you
wants - put some xlog() around the place where you add the call in the
profile (in the script). Be sure you create the dialog (use
create_dialog() before adding it into profile). After that, you can
check with MI function to see the profile content
(http://www.opensips.org/html/docs/modules/devel/dialog.html#id272772)

Hi Bogdan,
Thank you very much for the hints on troubleshooting. I'll work on that
troubleshooting and hopefully I might be able to fix the issues.

[OpenSIPS-Users] How to limit channel on bunch of called DIDs?
Hi! I'm a newbie with OpenSIPS administration and configuration and I searched on the mail archives regarding limiting the channels but only found the site regarding Concurrent calls limitation. I've been trying to grasp the whole idea about AVPops and dialog module but unfortunately I'm having a hard time understanding it. If ever, does anyone here be kind enough to point me to any available documents or sample configurations file that will help me limit the channels on inbound calls to a single or group of DIDs? Implementation will be done static first and hopefully once I got the whole idea, will be implementing a dynamic one.

Re: [OpenSIPS-Users] How to limit channel on bunch of called DIDs?
/local/sbin/opensips[1637]: Recive call variable : null null As for the channels limit value, do I have to define it on usr_preferences table? I have these records on the said table: mysql select * from usr_preferences; ++--+++---+--++-+ | id | uuid | username | domain | attribute | type | value | last_modified | ++--+++---+--++-+ | 1 | | 1234567890 || channels |0 | 3 | 1900-01-01 00:00:01 | | 2 | | 0 || called_number |0 | 12135551234 | 1900-01-01 00:00:01 | ++--+++---+--++-+ 2 rows in set (0.00 sec) Unfortunately, I'm not quite sure on what section or portion of opensips.cfg file I will have to put the loading of user preferences to the AVPs. Any inputs or suggestions will be greatly appreciated?
