Interdigit Timout

When a button (0-9) is pressed on your IP Phone, a timer starts till the IP Phone attempts to send the digits dialed up to that point.  This is known as the IP Phones Interdigit Timeout Seconds.  If you need to increase or decress this setting, you need to log into each device and edit the value in the Interdigit Timeout section of the IP Phones web user interface.

For Polycom IP Phones you can locate the Interdigit Timeout setting by going to the SIP Tab:

In this example, the IP Phone is configured to use 3 seconds to timeout the digitmap.
