The SIP-based Avaya J100 Series IP Phones provide country-specific network progress tones which are presented to the user at appropriate times. The tones are controlled by administering the COUNTRY parameter for the country in which the deskphone will operate. Each Network Progress Tone has the following six components:
Dialtone
Ringback
Busy
Congestion
Intercept
Public Dialtone
All countries listed in this appendix are applicable to the 96xx phones. Some of the dialtone entries have changed from previous releases to be distinctively different than the public dialtone entries.
