Trunk-to-TIE Access
It is possible to assign an extension of another PBX as the destination of incoming trunk calls to the own
PBX.
It is also possible to forward calls using a virtual PS. Using this method, trunk calls received at PBX-1 are
forwarded directly to the extension at PBX-2, even when using the PBX Code method.
