Cisco 88XX Timer for a Call Forward from the Phone

[krizvite]

Hi Community,

could you assist me please regarding the issue with call forward timer on the deskphone? If I press a call forward button on the phone during the call, new popup window will be shown where I have to press new number for call forwarding. 

Do you know if its possible to increase this timer how long the window for the new number will be shown? 

Thank you!

BTW could this be a T302 Timer? Call Transfer is a new outgoing call called like digit-by-digit... or is this another timer bcs t302 is a timer between digits..
