----
The command controls automatic answering mode for the incoming calls.

===[https://wiki.teltonika-networks.com/images/4/48/Quectel_BG96_AT_Commands_Manual_V2.3.pdf#page=114&zoom=100,68,473 ATS6 Set Pause before Blind Dialing]===
----
The command is implemented for compatibility reasons only, and has no effect. 

===[https://wiki.teltonika-networks.com/images/4/48/Quectel_BG96_AT_Commands_Manual_V2.3.pdf#page=115&zoom=100,68,97 ATS7 Set Timeto Wait for Connection Completion]===
----
The command specifies the amount of time(unit: second) to wait for the connection completion in case of answering  or  originating  a  call.  If  no  connection  is  established  during the time,  the  module  disconnects from the line.

===[https://wiki.teltonika-networks.com/images/4/48/Quectel_BG96_AT_Commands_Manual_V2.3.pdf#page=115&zoom=100,68,665 ATS8 Set the Timeto Wait for Comma Dial Modifier]===

===[https://wiki.teltonika-networks.com/images/4/48/Quectel_BG96_AT_Commands_Manual_V2.3.pdf#page=116&zoom=100,68,202 ATS10 Set  Disconnection Delay  after  Indicating  the  Absence  of Data Carrier]===
----
The  command determines  the  amount  of  time(unit: tenths  of a second)  during which  the  UE  remains connected in absence of a data carrier.

===[https://wiki.teltonika-networks.com/images/4/48/Quectel_BG96_AT_Commands_Manual_V2.3.pdf#page=116&zoom=100,68,838 AT+CSTA* Select Type of Address]===
----
The  Write  Command selects  the  type  of  number  for  further  dialing  commands '''ATD''' according  to  3GPP Specifications. Test command returns values supported a compound value.

===[https://wiki.teltonika-networks.com/images/4/48/Quectel_BG96_AT_Commands_Manual_V2.3.pdf#page=117&zoom=100,68,693 AT+CLCC List Current Calls of ME]===
----
The execution command returns the list of all current calls. If the command is executed successfully, but no calls existed, no information response but '''OK''' is sent to TE.

===[https://wiki.teltonika-networks.com/images/4/48/Quectel_BG96_AT_Commands_Manual_V2.3.pdf#page=119&zoom=100,68,242 AT+CR Service Reporting Control]===
----
The command controls the module whether or not to transmit an intermediate result code '''+CR: <serv>''' to the TE when a call is being set up.

If it is enabled, an intermediate result code is transmitted at the point during connect negotiation at which
the TA has determined which speed and quality of service will be used, before any error control or data
compression reports are transmitted, and before any final result code (e.g. '''CONNECT''') is transmitted.

----
The command controls whether or not to use the extended format of incoming call indication. When it is enabled, an incoming call is indicated to the TE with unsolicited result code +CRING: <type> instead of the normal '''RING'''.

===[https://wiki.teltonika-networks.com/images/4/48/Quectel_BG96_AT_Commands_Manual_V2.3.pdf#page=121&zoom=100,68,398 AT+CRLP Select Radio Link Protocol Parameter]===
----
The Write Command sets radio link protocol (RLP) parameters used when non-transparent data calls are originated. 

===[https://wiki.teltonika-networks.com/images/4/48/Quectel_BG96_AT_Commands_Manual_V2.3.pdf#page=122&zoom=100,68,752 AT+QECCNUM Configure Emergency Call Numbers]===
----
The command can be used to query, add and delete ECC numbers (emergency call numbers). There are two  kinds  of ECC  numbers: ECC  numbers  without (U)SIM  and  ECC  numbers  with (U)SIM. The  default ECC  numbers  without  SIM  is  911,  112,  00,  08,  110,  999,  118  and  119. The  default  ECC  number  with (U)SIM is 911 and 112.911 and 112 will always be supported as ECC numbers, and cannot be deleted. ECC numbers can be saved into NV automatically. If the (U)SIMcard contains ECC file, the numbers in ECC file can also be regarded as ECC numbers.

The maximal supported ECC numbers of each type is 20.

----
The command can terminate a call or calls (including both voice call and data call) with a specific 3GPP TS 24.008 release cause specified by the host.
