I need implement cisco ipt in a remote office with a uc500. The uc 500 will replace a traditional siemens pbx.
Currently this pbx and the main office pbx are using toll by pass with cisco routers.
The connection between the pbx and the cisco routers are via E1.
I want connect this office with the main office. the main office has a Siemens pbx connected to a cisco router via E1.
I want to know if I have the possibility to setup the uc500 to pass the call between them (the uc500<->routerA<->routerB<->pbx).
Exactly my question is, can I re-use the current dial peers in the cisco routerA (@ the remote office) and integrate those dial peers with the uc500?
