Hello
I need to write a CAC (Call Admission Control) module for an 802.11 AP (Access Point). The idea is to use a SIP Proxy to monitoring bandwith utilization according to codec, and allow or disallow new sessions, depending on resources. On a first stage I just want to limit the session to a fix number. For that, for each new session request (INVITE), I need to know how many active session there is already. I think using the module dialog but it is experimental. What is exactly its status? Is it usable for now? Is there another way to get information about the number of active sessions?
Thanks.
Regards, Michel
Hi Michel,
the module is in beta stage - there are still things to fix / improve, but it works :)... For your purpose, you should use the $DLG_count pseudo variable: http://www.openser.org/docs/modules/1.2.x/dialog.html#AEN187

Hi Bogdan
Thanks for your help. I always get a zero value. Do you have a cfg file example that use dialog module? I'm using v1.1.1. Do I have to move to the devel version? If yes Can I just take the devel version for dialog module and 1.1.1 for the rest?
Regards, Michel.

Hi Michel,
you need to enable the usage of the dialog module in order to work that PV. So, load the dialog module, define a flag for triggering the dialog creation and set it for INVITEs... http://www.openser.org/docs/modules/1.2.x/dialog.html#DLG-FLAG-ID
