[SR-Users] [OT] Accounting Drouting Gateway Selection

[Spencer Thomason]

Hello all,
I have a need to determine which calls go to which gateway.  The challenge is that CDRs are produced by a FreeSWITCH instance upstream of a provider side Kamailio proxy that handles route selection via drouting module.  The topology is like this:

customer proxy -> FS [1-N] (accounting) -> carrier proxy (route selection)

Does anyone have any ideas how to make the FreeSWITCH instances aware of which gateway actually received the call?

Thanks!
Spencer
