Disconnect Signaling Reliability
Use this procedure to classify the disconnect signal sent by the central office on
loop-start trunks as one of the following:
■
Reliable.
Signal sent within a short time.
■
Unreliable.
Signal may not be provided.
!
Security Alert:
Toll fraud can occur if you have loop-start trunks with unreliable
disconnect. In this situation, if someone calls you and you hang up, the
CO could send dial tone before the caller hangs up, allowing the caller to
place another call as if it originated at your company.
The setting selected applies to all trunks in the system because trunks cannot be
programmed individually. The reliable/unreliable setting does not apply to loop-
start trunks emulated on a T1 facility. If you specify a reliable disconnect for
trunks programmed with a short hold disconnect interval (see “Hold Disconnect
Interval”), active calls as well as trunks on hold may be disconnected. For more
information about reliable and unreliable disconnect and its implications, see the
Feature Referenc
e.
NOTE:
Certain features (Remote Call Forwarding and Transfer to outside numbers) and
applications (CMS, AUDIX Voice Power, and MERLIN MAIL) are not
recommended with loop-start trunks. See “Hold Disconnect Interval.”
