Dialing an ISDN number
When dialing an ISDN number, the D command is followed by the number and, if necessary, a subaddress (preceded by an
asterisk '*').
The dial command looks like this:
ATDisdn_nb*sub_addr : : dte_channel_id
in which:
isdn_nb*sub_addr is an ISDN number, followed, if necessary, by a subaddress.
dte_channel_id is the protocol number used. If this field is blank, the active protocol is used.
Examples:
ATD69855044
ATD69855044*5
ATD69855044::10
