I have put an IP phone (ext 4002)outside our network communicating through a checkpoint firewall. The phone registers with CCM, and gets it's DN(4002).
I tried placing a call to a DN (4001) inside our network from outside, and I am getting one way voice calls. The IP Phone (4002) outside the network, can hear the inside(4001) of the connection, but not vice versa.
I get the same result when I try to make a call via the PSTN from the 4002 number.
