Hi Spencer,

We use a similar approach as yours and use 302 Redirects coming from Kamailio instead of proxying the call (in our case we do it via LCR module in Kamailio). In FreeSWITCH you can then manually route these redirects and get your CDR data out of it.

Cheers, DanB

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?
