4.3.3.4 H, Hang-up Call
This command hangs up a call. The g20 terminates the call whether it is a data or voice call, and whether it is an incoming,
originating, waiting, or connected call.
A NO CARRIER message is returned to the terminal before the regular OK approval.
The following table shows the call states of the H command.
Note
To terminate (hang-up) a MO data/fax call while call is placed: Any character sent from the terminal to the g20
causes the Data/Fax call termination, and NO CARRIER is sent from the g20 to the terminal.
To terminate a held Voice call or to terminate a call out of a MTPY call, refer to “+CHLD, Call Related
Supplementary Services Command” on page 68.
