Non-password Auto Call Back Function
In addition to the standard modem-like security functions described in the previous
section, the Omni TA128 provides another simpler call back function. The Calling Party
Number (origination address) will be checked against the 5 pre-stored call-back numbers
before the B channel is connected. If the CPN is matched with any one of the numbers,
the incoming call will be rejected (without connection, hence without any charge) and the
TA128 will automatically call back using the matched phone number.
This function can be controlled by the following command:
AT*GC0
AT*GC1
The pre-stored numbers can be set using the following command:
AT*HCn=xxxx,
You will be prompted to enter the supervisory password first.
The AT*VC command can be used to list all the pre-stored numbers.
