Polycom IP 550 digit timeout

Is there a way to change the time it takes a call takes to time out, if a caller fails to enter something the digit map recognizes when the phone is actually off hook and waiting for digits? Currently if the phone is off hook and waiting for a digit map match, the phone will just sit there waiting forever. I would like to make it so that the phone hangs up on you, if you fail to tell it to do something within a certain amount of time. Anyone know how to make this work? Thanks in advance!


Check with polycom. if the phone has a dial plan (yep they do) then that is handled by the phone until something matches one of the patterns.
