• ATDL; (Voice) dials the exact number that was last dialed, including the DTMF tones
sent.
• ATDL (Data/Fax) dials the addressing information only (comma and tones are
discarded).
• If ATDL is sent before any Dial command was issued (mainly after Power On, when
the last number is an empty field), the G24 will return NO CARRIER, as mentioned
in the ITU V.25-ter standard.

H, Hang-up Call
This command hangs up a call. The G24 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.
Note: To terminate (hang-up) a MO data/fax call while call is placed: Any character sent from
the terminal to the G24 causes the Data/Fax call termination, and NO CARRIER is sent
from the G24 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 3-25.
The following table shows the call states of the H command.

IDLE Error 3 ("operation not allowed") or OK, depending

Single Active Call released
MTPY Active Call released (all calls)
Incoming call (RING) Call released
