How Do I?
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.
