Technical Reference for ZyXEL omni.net series

If an incoming SETUP message is offered with addressing information (i.e. the appropriate part of the called_party_number), this address will be compared with the MSN numbers assigned by the [AT&ZIn=s] commands. The call will be accepted using the specific protocol, if the assigned number of this protocol matches the received called party number.

NOTE: You are not required to enter the complete number string for the [AT&Zin] command. The last few distinguishable digits will be enough for the Omni.net to make the decision. Two phone number strings are said to be matched if their least significant 'n' digit(s) are identical, where 'n' is the number of digits in the shorter string.

Called_Party_Subaddress information within the incoming SETUP message can also be used to select the protocols and/or analog ports. In normal conditions Called_Party_Subaddress information is not used by the omni.net to select the protocols or services, but only indicates the subaddress (if any) to the DTE.
