I have in 1 site a call manager with ip phones and a traditional pbx. In other site I have another pbx. I have two gateways with E1 R2 interface connected to the pbxs and H323 in the routers. When I call from one pbx to another I don't have problem with the caller ID, but when I call from one PBX to the IP-Phones I don't have caller id in the IP-Phone, if I call from the ip-phone to whatever th called-id works well in the legacy phone.
Someone could give a clue please...
