[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

Where exactly are you positioned and want to get the gateway? It should
be either a via header or a Record-Route or Contact address. Of course,
if no b2bua in between.
Cheers,

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
