We would like to connect our Kerio Operator with Asterisk based PBX in one of our Branch offices.
The idea is to unify our telephone network and be able to call each other's extensions directly.
We have configured SIP Trunks on both ends and the calls are being placed successfully both ways.
However, for calls from Kerio->Asterisk the extension number is not preserved and corresponding External Numbers are used, as they are configured for every extension.
We are using an older version of Kerio Operator, so using "Exceptions to the outgoing routes" feature mentioned here is unfortunately not an option kb.kerio.com/product/kerio-operator/server-configuration-ker io-operator/mapping-external-and-internal-numbers-896.html
So in a nutshell, we have 2 "Providers", one of them is a VoIP Operator and another our branch office PBX. For one we do need to use individual External numbers per extension for outgoing calls and for another we'd like to use only extension numbers.
My question is if there are any workarounds to our case.
Maybe there is a way to connect these 2 systems in such a way that Kerio does not treat the other side as a standard provider and does not apply External Numbering rules.
Thank you in advance,

I hope I understood you correctly. For outbound calls you want to preserve the extension number in the From header. This can be configured easily in your outbound route. Configure it to not rewrite the caller's number (strip nothing, add no prefix).
