VVX 600 Dialer Digit Timer

I have a few VVX 600s and when you use the keypad on the physical phone for example you start typing a number 503-123 Pause for about 3 seconds or longer and the phone trys to dial that number when i need to enter 4 more digits it trys to auto call way too fast for our CEO and he wants his timer to be longer.

I have played with the Digitmap Timeout under SIP on the configuration web page and got no where.

Any help or ideas on how to do this?

We are using Lync 2013 right now..

UC Software Version 5.5.0.20556 Updater Version

Thanks in advanced!
