6.1.3 Operation
Note
For devices connected to a PBX other than the Main Unit, refer to the Troubleshooting for that PBX.
PROBLEM
• Cannot set the IP
address, subnet mask
address, and PBX IP
address to the SIP Phone.
• Cannot register the
SIP Phone.
• The SIP Phone cannot
connect to the PBX.
• Whenever you try to
make calls using a SIP
phone, a busy tone is
heard.
• The SIP Phone does not
ring.
The status of the port
property of an SLT
extension is FAULT.
PROBABLE CAUSE
• An unusable value is
being set.
• The necessary network
parameters are not set
to the SIP Phone.
• The wrong IP address,
subnet mask address,
PBX IP address, or
default gateway
address was entered.
• The Ethernet cable is
not connected
correctly.
• The DHCP server is not
active.
• The status of the port
that the SIP phone is
connected to is Out of
Service.
• The ringer volume is off.
• The telephone is
off-hook.
• There is a problem in
the wiring.
• The SLT circuitry is
damaged.
SOLUTION
• Set an IP address within the valid range.
IP address of the SIP Phone/PBX: "1.0.0.0" to
223.255.255.255 Subnet mask address:
0–255.0–255.0–255.0–255 (except
0.0.0.0 and "255.255.255.255")
• When not using the DHCP Server feature
or an external DHCP server, set the IP
address, subnet mask address, and enter
the PBX IP address. If necessary, also
enter the IP address of the default
gateway.
• When using the DHCP Server feature or
an external DHCP server, enter the PBX
IP address.
• Check each parameter and enter the
correct value.
• Check the Ethernet cable connections.
• Restart the external DHCP server.
• Confirm whether the DHCP Server feature
is enabled.
• Disable DHCP and re-enter settings as
appropriate.
• Change the port status from Out of
Service to In Service using Web
Maintenance Console.
• Turn on the ringer volume.
Put the telephone on-hook and restart the
PBX.
Disconnect all cabling between the PBX and
SLTs, and restart the PBX.
After restarting, if operation is normal, there is
probably a problem in the wiring or
connection. (For example, there might be a
short circuit in the switchboard or cabling.)
Consult a certified dealer.
