Did you notice the timing diagram in the datasheet? You'll want to control the IL91531N input pins according to this scheme.

is it necessory to use this dialler to make call. Bcoz you can have good option of SIM300 or SIM900. Because it is having connection of UART and also other protocol so you can call or sms on number.
