Command: +VSM=?
Response: + VSM: <cml>, <cmid>, <bps>, <tm>,<vsr>,<sds>, <sel>
<cml> Decimal number identifying the compression method (1, 128 to
133).
<cmid> Alphanumeric string describing the compression method
(UNSIGNED PCM, 8-BIT LINEAR, ADPCM, ULAW, ALAW, or

<bps> Decimal number defining the average number of bits in the
compressed sample not including silence compression (4, 8, or
16).

second, between timing marks. A value of 0 reports that timing
marks are not supported.

samples per second of the analog signal (7200 or 8000).
<scs> <range of values> containing the supported range of sensitivity
settings for voice receives (0).
<sel> <range of values> containing the supported range of expansion
values for voice transmits (0).
