Notes
• If the active call is a CSD call, and a waiting call is received, then the ME produces a BREAK while still in
online mode, and displays
- the +CCWA URC (as above) when the ME goes back to command mode while the waiting call is still active
and can be accepted;
- or the ^SCWA URC (as above) when the ME goes back to command mode after the waiting call has
ended.
• With the AT+CHLD command, it is possible to establish a multiparty call or to set the active voice call on hold
and then accept a waiting voice call (not possible with fax and data call). See also
• Users should be aware that if call waiting is activated (
enabled, too ( =1).
<n>
Otherwise, on the one hand, a waiting caller would be kept waiting due to lack of BUSY signals, while, on the
other hand, the waiting call would not be indicated to the called party.
• The AT+CCWA command offers a broad range of options according to the GSM specifications. However,
when you attempt to enable call waiting for a
ported , the setting will not take effect regardless of the response returned. The responses in these cases vary
with the network (for example "OK", "Operation not allowed", "Operation not supported" etc.). To make sure
