Configuration Task
Description
Step 1
At Site 1, define a VPN line (see page 41) and assign
VPN Line number to remote node number. Repeat
process for Site 2.
• Site 1 Line Number = 2
• Site 2 Line Number = 3
The VPN line number provides discriminator
to other line Groups. No two Line Groups
can share the same VPN line Number
The VPN line number must not exceed 240
Step 2
Set the VPN Incoming and OutGoing Group ID.
• For Site 1 OutGoing Group ID = 2
• For Site 2 OutGoing Group ID = 3
Repeat process for Site 2.
The Line group ID as an absolute reference
to VPN line. It is permissible for 2 VPN lines
to share the same Line ID in case where
redundancy is required.
Step 3
Apply the bandwidth restrictions and Line Control
parameters as appropriate.
Step 4
For Site 1, on the VoIP tab of the VPN line set the
destination VoIP Gateway to the IP address of the LAN
1 interface of the IPNC on Site 2.
• For Site 1 destination VoIP Gateway =
192.168.50.1
• For Site 2 destination VoIP Gateway =
192.168.200.10
The IPNC VoIP Gateway function resides
solely on it's LAN1 interface; the IPNC
listens for VoIP Gateway connections only
on the LAN1 interface IP address. This does
not preclude the LAN2 interface been used
for the VoIP transmission.
Step 3
Select the required VoIP options (ensure that optional
parameters are matched for Site 1 and Site 2)
• FAX transport
• Silence Suppression
• VoIP compression Type
Step 4
Add Short-codes (see page 39) as follows:.
For Site 1
• Short Code = 6003N
• Telephone Number =. <full stop>
• Line Group ID = 2
• Feature = Dial
For Site 2
• Short Code = 6002N
• Telephone Number =. <full stop>
• Line Group ID = 3
• Feature = Dial
Shortcodes define the rules and sets the
condition under which the IPNC will invoke
the Line.
