3.7.1 Direct Dial From Phonebook
The ISU 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 mem-
ory and SIM phonebook is possible through ordinary communications software which just gives the phone
number field to be filled and then use the D command to originate the call. Available memories may be que-
ried 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>[;]
