Failure to hear 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 9600 Series IP Deskphone does not require any action on the user’s
part. The TN2302AP board does not pass in-band DTMF tones.
Correcting a power interruption
If power to a 9600 Series IP Deskphone is interrupted while the telephone is saving the
application file, the HTTP/HTTPS application can stop responding. If this occurs, restart the
HTTP/HTTPS server.
Using the VIEW craft procedure for troubleshooting
Use the following procedure to verify the current values of system parameters and
file versions.
Note:
If so administered through OPSTAT, end users can access the Network
Information option from the Avaya Menu’s Phone Settings option to view (but not
change) most of the parameters associated with Craft Local Procedures. For
more information about this option, see the applicable user guide(s).
Important:
IPv6 operation is limited to a specific customer set and is not available for general
use.
Note:
You can use the ADDR option to view IP Addresses if needed. See Changing IP
address information on page 42 in Chapter 3. The IP Addresses might have been
entered incorrectly. Verify whether you were provided with correct IP
Addresses.
1. When you select VIEW from the Craft Local Procedure Screen, the following system
parameters display, as shown in Table 2: Parameter Values on page 67.
