Has anyone experienced not being able to dial between remote IP phones. I have this happening on two BCM systems. One is a BCM50 running 2.0 and the other is a BCM200 running 4.0. From each system you can dial from the remote IP phone to any of the digital sets but you cannot dial to a remote phone at another location/across tunnels. Do you need any keycodes besides the IP telephony client license?
