Dialing Completion
Timeout
Users might dial with incomplete phone number and wait for
several seconds but not finish the complete dialing. The
system will force to dial the incomplete number after the time
you set in this field to finish that call. For example, the phone
number is 03654321 and the dialing completion timeout is set
to 4 (secs). The user dials with 036 and stops to dial. After
passing through 4 seconds, the adapter will send out that
phone call automatically.
