Using a VTL Password 99
To place a hop-off call to 555-1212 in area code 903 through the Atlanta
system, a user on a remote system would dial 72919035551212. The 72
code sets up a VTL connection to Atlanta that incudes the Atlanta
system’s VTL password, and the remaining digits are used to dial the
number (9 accesses an outside line to obtain dial tone from the local
carrier, 1 accesses the long-distance carrier, and the remaining digits
specify the long-distance number).
If the same user used site code 62 to place a call to the Atlanta office,
only toll-free, emergency, and internal call would be allowed.
Toll Calls Without a
VTL Password
If a local user has configured his telephone to forward calls to a
long-distance number, then an incoming VTL call to that telephone does
not need to supply the local system’s VTL password in order for the call to
be forwarded.
Music On Hold If two users are talking on a VTL connection, and the first user places the
call on hold, the second user hears Music On Hold only if his local system
is configured to play it.
