Re: [Kamailio-Users] CDRTool and Prepaid

In my experience dealing with it, it is precisely at the point where multiple calls are involved that using a proxy for rating and mediation purely becomes an impossible headache. The conclusion I always came to in my implementations, which too always started out with the noble goal of dealing with it all in proxy, is that to properly handle this, I would need to extend the functionality to include a B2BUA through which the calls are run that can sit there and monitor them at a relatively low interval and record updates to their duration into the database. The B2BUA would need some sort of call control API, like Asterisk's Manager API, or whatever Yate has, so that an outside process can sit there and do statekeeping on the calls. You could do this without handling media by using the B2BUA in a purely signaling capacity, which I think is how Yate functions by default, and how Asterisk can function with the "directrtpsetup" option in sip.conf. It is then possible to know in reasonably real time the call duration without waiting for an accounting stop event and thus make the determination of whether another call should be allowed given the balance depletion. -- Alex Adrian Georgescu wrote: -- Alex Balashov Evariste Systems Web : http://www.evaristesys.com/ Tel : (+1) (678) 954-0670 Direct : (+1) (678) 954-0671 Mobile : (+1) (706) 338-8599
