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.
