Trouble Indication
System is not performing call
transfers properly.
Caller hears a ring, but
receives no answer.
User Response
Check to see if the user is
transferring to a valid extension.
Make sure the person being
transferred to is registered on the
system. If not, check to see
whether the system is administered
to allow transfers to nonregistered
numbers.
If the problem regards transferring
to an operator, check to see if an
operator has been defined on the
system.
Check to see if the telephone line
is properly connected to the
channel.
In addition, make sure service has
been assigned to the channel and
that it is in the INSERV state. If it
is in the facility-out-of-service
(FOOS) state, change it to the
manual-out-of-service (MANOOS)
state. Diagnose the IVP4 card and
then change it to the INSERV
state.
Also, check the PBX
administration of that channel.
For System 75, make sure that
channel to phone mapping has
been done correctly.
