What to do
1 Check the IP network to ensure the
following:
The IP network is not down.
Traffic is being routed between the
Digital Telephone IP Adapter unit and
RLC on the host PBX.
2 Contact your telecom administrator.
There might be problems at the host
PBX.
This is a normal occurrence and is caused
by the DSP activating a dial tone relay.
However, to eliminate stutter dial tone,
disable Dialtone Relay. Dialtone Relay
settings are in the Advanced Configuration
dialog box, which is available on the RLC
System Configuration Property sheet.
1 Check all cable connections to and from
the Digital Telephone IP Adapter unit to
ensure that they are all securely
connected.
2 Check the IP network and ensure that:
it is not down
traffic is being routed between the
Digital Telephone IP Adapter unit and
RLC on the host PBX
3 PING the RLC from the Digital
Telephone IP Adapter unit to verify IP
network connectivity.
It is possible that there is a synchronization
error between the Digital Telephone IP
Adapter unit and the host PBX. Contact
your telecom network administrator.
