If you were doing a direct forwarding from a PRI out to an external number, for example when an extension turns on call forwarding, then the Toshiba system will pass along the caller's Caller ID. When the voicemail or an operator is transferring a call offsite, technically they are making a new call and then connecting the other caller to the call. In this case, the caller ID sent out to the carrier is for the Voicemail port or the operator's extension.

The LVMU has no way to modify the caller ID on an outgoing call. This was possible with the IPEdge voicemail system and the most recent CIX software, but not for Stratagy LVMU
