+CRC - Cellular Result Codes SELINT 2
where
<type> - call type:
ASYNC - asynchronous transparent data
SYNC - synchronous transparent data
REL ASYNC - asynchronous non-transparent data
REL SYNC - synchronous non-transparent data
FAX - facsimile (TS 62)
VOICE - normal voice (TS 11)
AT+CRC? Read command returns current value of the parameter <mode>.
AT+CRC=? Test command returns supported values of the parameter <mode>.

3.5.4.2.7 Single Numbering Scheme - +CSNS
+CSNS - Single Numbering Scheme SELINT 0 / 1 / 2
AT+CSNS=
[<mode>] Set command selects the bearer to be used when mobile terminated single
numbering scheme call is established. Parameter values set with +CBST
command shall be used when <mode> equals to a data service.
Parameter:
<mode>
0 - voice (factory default)
2 - fax (TS 62)
4 - data
Note: if +CBST parameter is set to a value that is not applicable to single
numbering calls, ME/TA shall map the value to the closest valid one. E.g. if
user has set <speed>=71, <name>=0 and <ce>=1 (non-trasparent
asynchronous 9600 bps V.110 ISDN connection) for mobile originated calls,
ME/TA shall map the values into non-trasparent asynchronous 9600 bps
V.32 modem connection when single numbering scheme call is answered.
AT+CSNS? Read command returns current value of the parameter <mode>.
AT+CSNS=? Test command returns supported values of parameter <mode>.

3.5.4.2.8 Voice Hang Up Control - +CVHU
+CVHU - Voice Hang Up Control SELINT 0 / 1
AT+CVHU[=
<mode>] Set command selects whether ATH or “drop DTR" shall cause a voice
connection to be disconnected or not.
Parameter:
<mode>
0 - "Drop DTR" ignored but OK result code given. ATH disconnects.
1 - "Drop DTR" and ATH ignored but OK result code given.
2 - "Drop DTR" behaviour according to &D setting. ATH disconnects
