INTERDIGIT TIMEOUTS
Description
Allows an originating register to be made available for others if dialing is not completed
within a set time period.
Interdigit timeouts is 24 seconds until the first five digits have been dialed, 10 seconds until
the next five digits have been dialed, and five seconds thereafter.
After timeout, voice terminal dial pad button presses are interpreted as end-to-end signaling
requests and touch-tones are placed on the outside line.
Considerations
Interdigit timeouts also apply to data calls.
When a user dials out over a trunk set up for dial pulse rather that Touch-Tone service, the
interdigit timeout interval is involved.
The caller cannot speak to the called party until the
timeout expires (even though the caller may be able to hear the called party). Because the
timeout interval decreases as more digits are dialed, the problem is often noticed on tie
trunks since the user may dial fewer (or no) digits when using these trunks. If the user
presses the # button after dialing the last digit this timeout ends and the caller may speak
immediately.
