6) Telephone of an extension
does not ring.
First of all, deactivate all possible forwarding services
by dialing 85 through the phone and hanging up, and
then try again! If the problem persists, then check if the
problem arises from the telephone set by replacing it!
If there seems to be no problem with the phone, then
the exchange card has to be replaced.
7) No call is received from the
line.
A simple test is needed to be done in order to figure
out whether the situation has been originated from the
line or the exchange. For that purpose:
Cancel the phone of the extension 122.
Disconnect the problematic line from the exchange.
Make a two-wire connection between the extension
122 and the problematic line.
Set the exchange to the programming mode through
the system supervisor extension and dial:
877777, 800 + line no + 111 +0000
Call the extension 122 through the phone of the
extension 112.
Check if the phone of the extension 111 rings.
If the phone rings, then the problem is not related to
your exchange; there is a problem with the line. On the
other hand, if the phone does not ring, then the
exchange card may have to be replaced.
8) The exchange does not
operate properly.
Dial 744 through the telephone set of the extension
111. If the problem persists, then reset the exchange
and re-program it
.
9) IP extensions cannot
register.
Make sure the ethernet cable is connected via the
display indication of the ethernet switch on the LAN.
10) IP phones cannot be
called.
Check the codec settings of the IP phones and make
sure that the IP phone is registered to the system.
