No Ethernet CAUSE: When first plugged in, the IP Telephone is unable to

communicate with the Ethernet.

RESOLUTION: Verify the connection to the Ethernet jack, verify the

jack is Category 5, etc. Note that if the telephone is attached to a 30A

switched hub, upon loss of Ethernet connectivity, the usual “No

Ethernet” message is not displayed.

No file server

address CAUSE: The TFTP server IP address in the IP telephone’ s memory is

all zeroes.

RESOLUTION: Depending on the specific requirements of your

network, this may not be an error. If appropriate, either administer the

DHCP server with the proper address of the TFTP server, or

administer the telephone locally using the ADDR option as detailed in

the 4600 Series IP Telephone Installation Guide.

System busy CAUSE: Most likely, the number of IP endpoints on the Avaya media

server is already at maximum, Less likely, network resource is

unavailable.

RESOLUTION: The telephone was attempting to access a network

resource (DHCP server, TFTP server, or the Avaya media server) and

was not successful. The resource being called upon should be

checked for its availability. If it appears operational and properly linked

to the network, verify addressing is accurate and a communication

path exists in both directions between the telephone and the resource.

System Error CAUSE: The Avaya media server has an unspecified problem.

RESOLUTION: Consult your Avaya media server administration and

troubleshooting documentation.

During Registration

Extension error CAUSE: An invalid Avaya media server Registration extension has

been entered.

RESOLUTION: Re-enter the extension if mis-entered initially. If

appropriate, verify proper extension with respect to switch

administration.

Extension in use CAUSE: The specified extension is already in use, according to the

Avaya media server.

RESOLUTION: Wait a few minutes, and try again. This will work for

the case when the extension is correctly administered, but service was

interrupted and the Avaya media server is not yet aware of that fact.

Otherwise, verify proper extension with respect to switch

administration.
