Entering the Private Network Number
The Private Network ISDN (or PRI) Number provides a second
number that can be used to call the ViewStation EX system (for
example, the company’s PBX has two different lines coming from
different network providers). It provides the correct numbers to the
caller for the additional lines needed after the connection of the first
line.
The Private Network Number can also be used to tell the PBX that
additional calls should be routed internally within the PBX instead
of going outside the PBX through the trunk line. In other words, the
Private Network Number can be used as a “fake” number which the
PBX handles as an internal number.
To access the Private Network ISDN (or PRI) Number screen:
Select System Info > Admin Setup > LAN/H.323 > Global Address
> Private Net
.
This screen is only accessible if a BRI network interface is attached
to the system. The private number is generally obtained from the IT
manager or the network administrator.
Note
Some PBXs always signal the same called number independent of
which number was used to call an endpoint. The private number
method might fail in this situation.
