Troubleshooting Guidelines
DTMF Tones
SIP telephones send DTMF tones according to the SEND_DTMF_TYPE parameter setting. The
default setting of this parameter sends DTMF "tones" as "telephone event" RTP packets per
RFC 2833. Whether a non-SIP telephone hears these DTMF tones depends on whether the
Avaya Communication Manager media resource converts the "telephone event" RTP packets
into audio RTP packets.
Power Interruption
If power to a 9600 Series SIP IP Telephone 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.
Installation Error and Status Messages
The 9600 Series SIP IP Telephones issue messages in the currently selected language, or if the
telephone is logged off, in the language specified by the SYSTEM_LANGUAGE parameter
value. If English is not the selected language, the telephone displays messages in English only
when they are associated with local procedures, for example, the VIEW Craft local procedure.
Most of the messages in
telephone resets. The most common exception is Extension in Use, which requires manual
intervention.
