 Posted: Wed Dec 03, 2008 1:45 pm Post subject: [Freeswitch-users] CDR generated on maximum sessions reach |
 |
|
Hello everybody,
I am new to the list and I hope I can find some help here, regarding an issue I am experiencing with the CDRs written by Freeswitch.
The thing is, I am using the "max-sessions" and the "sessions-per-second" parameters in switch.conf.xml to limit the maximum number of simultaneous calls, I want to go through my Freeswitch server.
These options are working well, but I was expecting to have CDRs generated for the calls, that are dropped when the limit is reached.
Unfortunately there is no such one.
My question is: Is there an option, which allows the generation of CDR, when a call is dropped, because the maximum sessions limit is reached?
If there is no such option, is there any way to achieve it? Probably by using the the mod_limit module? Can you, please tell me how to do it?
Any kind of advice is welcomed. Thank you in advance.
Regards,
Lachezar |

Lachezar,
These are good questions! I'll research them and let you know what I find out.

This is not possible. A CDR cannot be generated without a session, and a session will not be generated if the max sessions limit has already been reached...

mod_limit is most definitely your best option at this point. If you haven't read this yet please do:
http://wiki.freeswitch.org/wiki/Mod_limit
In the example on that page, you have a "limit_exceeded" extension which would show up in your CDR, or you can set a specific channel variable which will magically show up in an XML CDR. (You can modify CSV CDRs to have any custom channel variables as well. See http://wiki.freeswitch.org/wiki/Cdr which refers to the <templates> section of conf/autoload_configs/cdr_csv.conf.xml)
Try adding the limit app in your dialplan and have the limit_exceeded extension as well. You could set the limit really low for the sake of testing before setting it to the value necessary for your production deployment.
Let us know how it goes.

Michael’s advise here is dead on... The whole point of the session limiter (and SPS limiters) is to keep the box from melting down... Say in the event of a DoS (or a telemarketer)... If you want to do a soft limit that’s just want mod_limit is for and will allow you to do 2 things when used in conjunction with the max_sessions and sps limits... 1) Soft Limit and still log the calls 2) still have a hard limit that keeps the box for falling over dead...
You can do this with a simple step at the top of your dialplan that mod_limits everything together...
