Comment
Outgoing call is being initiated by AG as result of
a HF request . Use this AT command as positive
confirmation of:
HFG”Dnnn”
HFG”D>mmm”
HFG”L”
“OK” is sent to the HF.
A call record in state “dialling” is created.
<number_string> and <type> are optional and will be
stored in the call record if given.
<type> must be in range 128..175
Refer to section 7.2.5
Outgoing call:
Remote party has been reached and is being alerted;
may not be used if the telephone network does
not provide this information; state of call record is
changed to “alerting”.
Outgoing call:
Remote party has answered the call; state of call
record is changed to “active”.
Outgoing call: use if a call is initiated on the HFG and
was not requested by HF.
“OK” is not sent to the HF.
A call record in state “dialling” is created.
<number_string> and <type> are optional and will be
stored in the call record if given.
<type> must be in range 128..175
Refer to section 7.2.5
Command also used to inform HF about remote rejec-
tion of outgoing call
Release was initiated either locally or remotely
Returns the list of current calls
Value:
0 =non-verbose mode for AT+HFGC? (default)
1 = verbose mode for AT+HFGC?
For <indicator_id> and <value> see Table 3.31.
Command is recommended to be used only with
indicator IDs 1(service), 5 (signal), 6 (roam) and
7(battery charge level). For all other indicators
(2-call, 3-call setup, 4-call held), the appropriate
call managing AT commands are recommended to
be used. These commands send the indicators
automatically.
Command used to respond to HFG”OP?”
Sends “ERROR” to HF. Needed on HFG”D>mmm” if
memory location is invalid or on HFG”L” if last dialed
number not available.
“+CME ERROR: <cme_codedec>” is sent to HF if HF
did enable this feature earlier. Otherwise a simple
“ERROR” is sent to HF.
“+BSIR:0” or “+BSIR:1” is sent to HF. SLC must exist
and Bit 3 of S596 (HFG supported features) must
have been set at boot time. Ringtone signal must be
provided by external circuit.
