Question
The telephone does not ring when there is an
incoming call.
Suggestions
• Make sure the Cat-5 network cable
is plugged into the LAN port of the
telephone base and the network wall
jack with Power over Ethernet (PoE).
• The cordless handset may be too far from
the telephone base. Move it closer to the
telephone base.
• Check your SIP server or telephone
administrative settings. Refer to the SIP
Phone Configuration Guide for details.
• If other SIP telephones in your hotel are
having the same problem, the problem is
in the wiring or network server. Contact
your telephone service provider (charges
may apply).
• Other electronic products such as HAM
radios and other DECT phones can cause
interference with your cordless phone.
Try installing your phone as far away as
possible from these types of electronic
devices.
• The Cat-5 network cable may be defective.
Install a new Cat-5 network cable.
• Remove the battery and then install it
again. Then place the cordless handset in
the telephone base. Wait for the handset
to synchronise with the telephone base.
Allow up to one minute for this to take
place.
