why don’t you hook your http_queries up to the relevant SIP packets passing by?
INVITE -> start
180/183 -> ringing
200 -> pickup
BYE/CANCEL -> end
It’s quite straightforward to get that cleanly in your configfile, and it give you a massive control over things. (just be aware of packets arriving twice ;) )
Anyhow, that’s how I typically handle this one. You can always also combine it with CNXCC, which is great for prepaid! Or do something from external with dlg.dlg_end to kill specific calls which are going over their limit.
But, I’m sure others will have even better ideas !
Grtz,
