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.
