3. If the 4600 Series IP Telephone is not communicating with the system (DHCP, TFTP, HTTP
or Avaya Media Server), make a note of the last message displayed. Consult the system
administrator.
4. If you expect the telephone to be IEEE-powered, verify with the LAN administrator that IEEE
power is indeed supported on the LAN.
Note:

DTMF Tones

H.323 telephones do not send DTMF tones to non-H.323 telephones. The failure to hear DTMF
tones sent by a far-end 4600 Series IP Telephone does not require any action on the user's
part. The TN2302AP board does not pass in-band DTMF tones.

Power Interruption

If power to a 4600 Series IP Telephone is interrupted while the telephone is saving the
application file, the TFTP application can stop responding. If this occurs, restart the TFTP
server.
