[Asterisk-Users] H323 gateway

[Asmine Ouloube]

I would like to made  a H323 Gateway with asterisk.

                                                    -------------- remote
gateway B ------PBX-B
                                                   |
  PBX-----------* gateway ---------remote gateway A--------PBX-A

I have installed all channel h323 drivers and my E1 card.
Now , I have to configure the h323.conf and  the extension.conf.
But I don't know:
- where to put the route of the differents called numbers
 for example: if i want to call a phone which is on the PBX-A .How should I
make? Which file must I configure? Where should I put the remote gateways
adresses ?

Can someone help me, please?

Thanks!!
