Avaya 555-233-128 Manuel D’Utilisation

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 

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 

page 54 for information.

●

Use the QoS option to verify QoS parameters.

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:

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 

 later in this chapter for more information. 

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.

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.
