Avaya B189 - Failure to Hear DTMF Tones; Correcting a Power Interruption; Using the VIEW Procedure for Troubleshooting

Failure to hear DTMF tones
As H.323 telephones do not send DTMF tones to non-H.323 telephones, the user need not
perform troubleshooting for failure to hear DTMF tones from a B189 phone. The TN2302AP
board does not pass in-band DTMF tones.
Correcting a power interruption
If power to a B189 Conference phone is interrupted while the phone is saving the application
file, the HTTP/HTTPS application can stop responding. If this occurs, restart the phone.
