Call Forward Mode
The V85 IP Phone supports three different kinds of call forward function: Immediate
Forward, Busy Forward and No Answer Forward.
Field Description
Immediate Forward Check the Immediate box and enter the immediate
forward number in the field. For example, if user A’s
phone has Immediate checked with the number set to
555-5555, then all incoming calls for A’s phone will
be forwarded to number 555-5555 immediately.
Note: When the “immediate forward” is enabled, the “busy forward” and “no
answer forward” cannot be enabled at the same time.
