SIM5300E AT Command Manual V1.02
Reference V.25 te r Note:
Parameter "I" and "i" only if no *#code is within the dial string<n> is
default for last number that can be dialed by ATDL.
*# codes sent with ATD are treated as voice c
alls. Therefore, the
Command must be terminated with a semicolon ";"See ATX Command
for setting result code and call monitoring parameters.
Responses returned after dialing with ATD.
For voice call two different responses mode can be determined. TA
returns "OK" immediately either after dialing was completed or after the
call is established. The setting is controlled by AT+COLP. Factory default is
AT+COLP=0, this cause the TA returns "OK" immediately after dialing was
completed, otherwise TA will returns "OK", "BUSY", "NO DIALTONE", "NO
CARRIER".
Using ATD during an active voice call:
When a user originates a second voice call while there is already an
active voice call, the first call will be automatically put on hold.
The current states of all calls can be easily checked at any time by using
the AT+CLCC Command.
