First of all - sorry for the mistake. My knowledge of English is rather poor. We take accounting information (Acct-Session-Time) from Cisco CS2800 which provides us very reliable info about duration of calls. But before call will be established there is some complex logic with rewriting of Request-URI in multiple steps. We need to track all these steps for our internal purposes. We could do it in a different ways and one of them we consider is to generate Start-messages (or some other message) for each INVITE passed though OpenSER exactly then INVITE is arrived. -- With best regards!

For example if UserA calls UserB and UserB wants to redirect all calls to UserC and UserC redirects all calls to UserD in case of failure etc. The main problem is that if I make a huge number of rewrites or RURI all I can send to RADIUS in Start-message is a combination of from-uri, to-uri and request-uri. All intermediate steps will be completely lost - - in the upper example RADUIS won't know anything about UserC. That's not good fo me. To resolve this problem I initially decided to log all INVITEs even they and the best way to do so is to mimic the behavior of Cisco which sends Start-messages on each INVITE and not on 200OKs. Maybe there are other ways to keep information about previous Request-URI in the body of SIP-message? -- With best regards!

2008/2/15, Bogdan-Andrei Iancu <bogdan(a)voice-system.ro>ro>: In my case - no. We don't use accounting from OpenSER for these purposes cause it can't generate Acct-Session-Time at all. We rely on Cisco's generated accounting info. Earlier we used asterisk b2bua for this task. Ok, I'll look there. -- With best regards!
