VoIP & PSTN
Based on the distributed architecture concept, VoIP extensions are off-premises extensions reachable
through VoIP calling party. You can call a VoIP extension by dialing a simple extension number as if
you are dialing a local extension, although the VoIP extension may be physically located in a remote
office thousands of miles away. Since the call is established via the Internet, voice quality may be
subject to network conditions. In addition to calling remote offices, you can also use VoIP extension to
go Off-Net – a way to make outbound calls from the remote office. The main reason for making Off-Net
calls is to save long distance charges. Please select the VoIP & PSTN icon:
Parameter Description
GK Security Level
(Off-Net Security
Level)
The Off-Net Security Level controls all incoming Off-Net calls with unknown
privilege. An incoming Off-Net call
’ s privilege is known if and only if the call is
in IPX mode and originated from a remote extension. All other types of
incoming Off-Net calls have unknown privilege, therefore are regulated by this
setting.
High:
This level requires the Post-Dialing Code to be consisted of a “ 9 ” followed by a
valid Virtual User ID and Virtual User Password. The user ’ s toll restriction
setting will restrict the Off-Net call. For example, if the toll restriction of the
virtual user is set to
“ Local ” , then the Off-Net call can only be made to local
numbers. If the toll restriction is set to “ Internal ” , then Off-Net calls are not
allowed. Also, people who are not a virtual user of the remote office cannot
make Off-Net calls via this office.
Medium:
This level requires the Post-Dialing Code to be consisted of a “ 9 ” followed by
the Local Off-Net Password (described later). There is no toll restriction for this
level. People who don
’ t know the Local Off-Net Password cannot make
Off-Net calls via this office.
Low:
This level requires just a “ 9 ” as the Post-Dialing Code to make Off-Net calls,
and there is no toll restriction for this level. Use this level with caution because
it allows virtually everyone to make Off-Net calls.
Local off net code
(Local Off-Net
Password)
Please select a four-digit number as the Local Off-Net Password which is
required to make Off-Net calls when the Off-Net Privilege Level is set to
“ medium ” (as described above).
