Hi, first of all I'm sorry for this cross-posting, but I think it could be interesting for any SIP proxy with accounting capabilities.
But I think this is too complex, isn't it?
It is complex, but not impossible.
I think is is feasable to do accounting on the proxy _IF_ you can trust your gateways and make use of that trust.
Start accounting on receipt of a 200 OK on an INVITE request.
Stop accounting: 1) On 200 OK (or maybe 481 or other response) from the gateway in response to a BYE. 2) On BYE from the gateway
