This isknown as temporary registration. If a forward destination is then assigned for this PS, all calls to that extensionnumber will be forwarded to the assigned destination. Using this setting to forward calls to outside destinationsor destinations at another PBX allows those destinations to receive calls as if they were within the PBX. Inaddition, depending on system programming, the forward destination can use some of the features of the PBX.This can be especially useful for a cellular phone user, who can use his cellular phone as if it were his extensionwhen he is away from his desk.Document Version 2009-12 Feature Manual 33919.1.2 Virtual PS
