Cause/Resolution
CAUSE: The telephone and the H.323 call server have
agreed to carry out the Time-to-Service (TTS) feature, and
the user has indicated a need to communicate with the call
server (e.g. by going off-hook or by pressing a feature
button) when the telephone does not have a TCP
connection to the call server. This typically occurs during a
brief interval after completion of registration, or as a result
of a network outage that caused an existing TCP
connection to be lost; the message indicates the telephone
acknowledges the user intent and is attempting to
re-establish the TCP connection.
RESOLUTION: The telephone will automatically attempt
to re-establish the TCP link for an administrable period
(75 seconds is the default), after which the telephone will
attempt to register with the next gatekeeper on its list. If
the network outage continues, appropriate analysis of the
outage should be conducted.
CAUSE: The 46xx telephone is attempting to discover
(and register with) the Gatekeeper at IP Address
aaa.bbb.ccc.ddd.
RESOLUTION: If this message appears for more than a
few seconds, especially if the IP Address keeps changing,
the telephone is unable to contact the Gatekeeper. Verify
network connectivity between the telephone and the
Gatekeeper, or revise the Gatekeeper addresses in the
DHCP/script files to point to different Gatekeepers. See

Servers (H.323 Only), DHCP,
HTTP.
CAUSE: The user is on a call when the network
connection between the telephone and call server is
interrupted, but the call stays connected. The telephone
automatically starts procedures to register with the call
server again. However, until registration succeeds, the
user has no access to Avaya Communication Manager
features and functionality. This message alerts users to the
lack of connection to the call server.
RESOLUTION: This is the same message, with the same
implications and Resolution as
valid registration to occur, or press # to interrupt the search
and re-initialize manual or DHCP/script files
procedures. on page 150.
