Configuring Advanced ISDN Port Settings

In some areas, it may be more economical to use a port configured for standard
voice calls to support a data call, called Data over Voice Bearer Service, or more
commonly, Data over Voice (DOV).
You can configure the BayStack 820 ISDN Router to validate an incoming data
call by examining the ISDN subaddress associated with that call. For such a call to
be distinguished from a normal inbound voice call, you can use one of the
Directory Numbers, a special subaddress, or a combination of the two to
determine whether or not an inbound voice call is a DOV call.
