Specify Progress Descriptor value range for in-band signaling
During call establishment, several OTA messages may include a Progress Indicator
information element that indicates whether the network uses in-band DTMF
signaling.
3GPP TS24.008 (section 5.5.1 and section 10.5.4.21) indicates the valid range of
Progress Descriptor values. This command can be used to specify one of two
possible ranges to accommodate differing interpretations of the specification.
This setting takes immediate effect (does not require a restart), and persists across
power cycles.
Usage:
• Execution: AT!AVINBANDRANGE=<range>
Response:
OK or ERROR
Purpose: Specify the range of possible Progress Descriptor values.
• Query: AT!AVINBANDRANGE?
Response:
<range>
OK
Purpose: Return the range of possible Progress Descriptor values.
Parameters:
<range> (Progress Descriptor value range)
• 0=Default (1,2,3,6,..,20)
• 1=Alternate (1,2,3,6,..,0x20)
