Refer to the exhibit. Callers dial 0 to reach an outside line. When they try to place calls to directory
services (322) or services (422), they hear the reorder tone. What needs to be edited in the dial
peer to allow these calls to complete successfully?
A.
The destination pattern is incorrect. It needs to start with a 9.
B.
A “prefix 1” statement needs to be added to the dial-peer configuration.
C.
The forward-digits all command needs to be applied to the dial peer.
D.
The destination pattern needs to be edited so that the first digit that is matched is a 0.
E.
The destination pattern needs to be edited so that the first digit that is matched is a 0 and the
forward-digits all command needs to be added to the dial peer.
F.
The destination pattern needs to be edited so that the first digit that is matched is a 1 and the
forward-digits all command needs to be added to the dial peer.
G.
The destination pattern needs to be edited so that the first digit that is matched is a 0 and the
forward-digits 3 command needs to be added to the dial peer.
Explanation:
Since the callers dial 0 before any actual number to go outside line, they should
have a destination pattern starting with 0 to place a successful call to directory services or other
services. The forward-digits command controls the number of digits that are stripped before the
dialed string is passed to the telephony interface. On outbound POTS dial peers, the terminating
router normally strips off all digits that explicitly match the destination pattern in the terminating
POTS dial peer. Only digits matched by the wildcard pattern are forwarded. The forward-digits
command can be used to forward a fixed number of dialed digits, or all dialed digits, regardless of
the number of digits that explicitly match the destination pattern.
