Cisco Voice Gateway(H323) with FXO or FXS configured to work as passby question

[Australian]

Hi Guys;

Our customer has a request, but I'm not sure if it can be configured on voice gateway?

The scenario is I my trying to connect my cisco h323 voice gateway with traditional PBX via FXO or FXS port, is it possible that VG work as bypass?

(The result will be Analog phones in Traditional PBX can directly call Cisco IP phones and Cisco IP phone can Call back directly too. )

I know FXO will need to transfer to the dedicate number using connection plar XXXX, is it possible to directly transfer all the call to CUCM?

please refer the topology in attachment

Thanks for helping.

Yes it's possible, you'll obviously be limited to the number of FXS/FXO you have and you'll have to send the calls to a single number, with a PLAR, you probably want to direct them to an AA so then they can dial the DN they're actually trying to reach.

Hi Jaime Valencia,

Thanks for you reply.

Is it possible to DIRECTLY Calling from Traditional phones to Cisco IP phone instead of entering to an AA?

I was wondering whether there is a solution that the voice gateway can work something like a transparent mode.
