There´s the possibility to create speeddial on each digit from 2 to 9 on the handset.
now my consideration:
Would it be possible that a long press of a digit during a conversation leads to Xfer via non-transfer MPK with the stored speed dial of the key in attended transfer mode?
Then the transfer with query to the 8 most important participants would be very smart and above all very easy to explain.
it would be a good idea
Good, same for WP and rest wireless
Speed dial for everyone !
