AT+HFCA
Answer an incoming call. “ATA” will be sent to the AG. In return, the audio gateway shall
update its “+CIEV” indicators (“call=1” and “callsetup=0”) and send appropriate messages to
the HF. Upon receipt of a “+CIEV” message, HF will notify its host by a “HFI<indicator>,<value>”
message. Please refer to section 7.1.15 on page 66.
AT+HFCH
Reject incoming call / terminate ongoing call. “AT+CHUP” will be sent to the AG. In return,
the audio gateway shall update its indicator “call”=0 and send the appropriate “+CIEV”
message to the HF. HF will notify its host by a “HFI<indicator>,<value>” message. Please
refer to section 7.1.15 on page 66.
AT+HFC”nnn”
Initiate a new call from HF to the number specified by the number string “nnn”.
This command will send “ATDnnn” to the audio gateway.
AT+HFCM”mmm”
Initiate a new call from HF to the number stored in memory location “mmm” of the AG.
This command will send “ATD>mmm” to the audio gateway.
AT+HFCL
Initiate a new call from HF to the number last dialled by AG. “AT+BLDN” will be sent to the
AG. In return, the audio gateway shall update its indicator “callsetup”=2 and send the
appropriate “+CIEV” message to the HF. HF will notify its host by a “HFI<indicator>,<value>”
message. Please refer to section 7.1.15 on page 66.
The CLIP feature is enabled by setting Bit 2 (value=4) in the HF supported features S
register 581. Subsequent AT&W and ATZ is required to take effect. If this bit is set at boot
time, the following actions are carried out automatically:
Response to action no. 3 will be indicated by either HF”CLIP,OK” or HF”CLIP,ERROR” after
the “CONNECT…” message.
The CCWA feature is enabled by setting Bit 1 (value=2) in the HF supported features S
register 581. Subsequent AT&W and ATZ is required to take effect. If this bit is set at boot
time, the following actions are carried out automatically:
Response to action no. 3 will be indicated by either HF”CCWA,OK” or HF”CCWA,ERROR”
after the “CONNECT…” message.
1. The according flag is set in the HF service record.
2. The according flag is set in the BRSF-message on Service Level Connection establishment
3. The SLC message “AT+CLIP=1” is sent automatically once the SLC is established
1. The according flag is set in the HF service record.
2. The according flag is set in the BRSF-message on Service Level Connection establishment
3. The SLC message “AT+CCWA=1” is sent automatically once the SLC is established
