Using the Call Transfer feature differs by user and by phone type. The same is true of the Hold feature in Standard Local Survivability (SLS) mode. Call Transfer also works differently in DCP/IP phones and analog phones in the survivable mode. Some limitations of the Call Transfer feature are:
The established call must be initiated from a local station (administered on this Branch Gateway) or from an incoming trunk. You can make only point-to-point call transfers to a phone that is local to the same Branch Gateway.
Does not support E-911 calls
Does not support the Conference button on any phone
Does not support trunk-to-trunk transfer (for example, for voice messaging)
