84 4600 Series IP Telephone Installation Guide
2. If you are using static addressing:
● Use the View command to find the names of the files being used and verify that these
filenames match those on the TFTP or HTTP server. See The View Administrative
Option on page 85 for more information. Check the Avaya Web site to verify whether the
correct files are being used.
● Use the ADDR option to verify IP Addresses. See Static Addressing Installation on
page 54 for information.
● Use the QoS option to verify QoS parameters.
See Chapter 3: Local Administrative Options
.
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:
Note: Because the 4601and 4601+ IP Telephones do not have a display, they are
limited in their ability to provide visual feedback and error messages. See
Troubleshooting the 4601 IP Telephone
later in this chapter for more information.
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.
