screen is displayed.

; the Add Files screen is displayed.

Auxiliary or Auxiliary M5K/M8K tab, for each of the file types you

37.2 Call Progress Tones (CPT) Files
Call Progress Tones (CPT) files contain definition of the Call Progress and User-
Defined Tones to be detected/generated by the Media Gateway board.
CPT file may contain definitions of the following tones:

Call Progress Tones

User-Defined Tones
The Call Progress Tones are mostly used for Telephony In-Band Signaling
applications (e.g., Ring Back tone). Each tone can be configured as one of the
following types:

Continuous

Cadence (up to 4 cadences)

Burst
A tone can also be configured for Amplitude Modulated (AM) (only 8 of the Call
Progress Tones can be AM tones). The Call Progress Tones frequency range is 300
Hz to 1890 Hz.
The User-Defined Tones are general-purpose tones to be defined by the user. They
can be set only as 'Continuous' and their frequency range is 300 Hz to 3800 Hz.
The maximum number of tones that can be configured for the User Defined and Call
Progress Tones together is 32. The maximum number of frequencies that may be
configured in the User Defined and Call Progress Tones together is 64 (each tone
may be composed of more than one frequency).
