I have two remote locations and 1 central office that all use a VoiP system located at the central office. We have a TZ210 in the central office and TZ105 at the remote locations. The phone system works fine except when a remote phone calls another remote phone.
For example when a phone at remote location 1 calls a remote location 2 phone. The phones ring and connect but there is no sound on the call?
I'm assuming that we have to configure the TZ210 at the central office to route VPN traffic to the other tunnel but I don't know how to configure that.
Thanks in advice for the help on this one!
