|
In some instances, after dialing a star code the CO responds with a second dial tone as a prompt to enter additional digits. Once a star code is accepted by the communications system, the Second Dial Tone Timer is activated and set to the programmed value. If dialing is attempted before the Second Dial Tone Timer expires, the call is treated as though it had violated calling restrictions and is not completed.
!SecurityAlert:
If the Second Dial Tone Timer is set to 0 ms and a caller begins dialing additional digits before the second dial tone, system restrictions may be bypassed and a restricted call may be routed. Careful administration of the Second Dial Tone Timer prevents the caller from bypassing call restrictions in this manner.
Marked System Speed Dial entries (entries that do not display) are not affected by the Second Dial Tone Timer setting. If the Central Office does not immediately supply dial tone when a star code is entered and a Marked System Speed Dial entry uses star codes, then the appropriate number of pauses (each 1.5 seconds) must be programmed in the entry following each star code.
