D> - Direct Dial From Phonebook
The Iridium 9523 and SIM contain phonebooks which have a phone number and an alphanumeric field for
each phonebook entry location. The use of V.25ter dialing command ensures that direct dialing from
phone memory and SIM phonebook is possible through ordinary communications software which just
gives the phone number field to be filled and then uses the D command to originate the call. Available
memories may be queried with Select Phonebook Storage test command +CPBS=?, and location range
for example with Read Phonebook Entries test command +CPBR=?.
Execute commands:
D><str>[;]
Originate call to phone number which corresponding alphanumeric field is <str> (if possible, all available
memories should be searched for the correct entry). <str> is of string type value and should enclosed by
"" (e.g., "John").
D> mem<n>[;]
Originate call to phone number in memory mem entry location <n> (available memories may be queried
with Select Phonebook Storage test command +CPBS=?).
