Multiple Call Forward

[Flora_Yealink]

Do you mean you want to support below scenario ,
T38 configure DSS key 1 as forward button , value is the extension number for example 101
DSS key as forward button ,value is VM number.
when you press the DSS key 1 , the phone will forward all the incoming call to the extension number 101
when you press the DSS key 2, it will turn off the forward feature .
if you press the DSS key 2 again , the phone will forward all the incoming call to the VM number
right ?
