Hello,
I use a modem Huawei E1550. I need to know about the call forwarding. Before the called subscriber picks up. How to do it?
Example:
ATD123456789; # Voice call
The forwarding. # Alert by modem (what I need!)
+ COLP: "0146290928", 129,, "JOE" # alert by modem: the caller picked up the phone
If the E1550 is not possible, please advise the other modem.
