I am new to IP Telephony and have been experimenting a bit with some new equipment which my company bought. So far I have succeeded installing CME on both 2801 and 2811 routers. I also have CME 4 on both of them and have 7960,7970,7920 and 7095 phones working ok.
We have two offices connected through a 1024kbit ADSL connection. We want to install one router in each office and be able to link both CME's so that when a certain range of numbers is dialed, it is either sent to the other office or kept locally. We also need to interface with a normal PABX (through a couple FXO interfaces)in one of the offices and it should be possible to call numbers to this PABX from both sites.
Can someone please guide me through the process of doing this, as I could not find scenarios like this on the net.
