Data Routing: Examples
10.3.4 WAN PPP
A VoIP link across a leased line requires the Control Unit at both ends to have a Voice Compression Module installed.
These provide for a fixed number of channels to use VoIP at any time. They are used to compress voice down to either
6k3 (G.723) or 8k (G.729) and provide echo cancellation.
Both ends must using the same version of software and configured to use the same speed and compression.
At Site A on IP address 192.168.42.1
1.Create a Normal Service:
The Account Name and password is presented to the remote end, therefore must match the User name and password
configured at Site B. The Encrypted Password option can only be used if the remote end also supports CHAP.
2.Create a User:
Under the Dial In tab tick Dial In On. This User account is used to authenticate the connection from the Site B. As the
Service and User have the same name these two configuration forms are automatically linked and become an Intranet
Service. The User password is displayed at the bottom of the Service tab as the Incoming Password.
· Name: SiteB
· Dial In | Dial In On: Enabled.
3.Create a RAS service:
If CHAP is to be used on this link, then the Encrypted Password option must be checked in the Service and in the RAS
service. The name of the RAS service must match the name of the Service at Site B. If the RAS service is given the
same name as the Service and User, they are automatically linked and become a WAN Service. Ensure that the
Encrypted Password option is not checked when using a WAN Service.
4.Edit the WANPort:
Note - do not create a new WANPort, this is automatically detected. If a WANPort is not displayed, connect the WAN
cable, reboot the Control Unit and receive the configuration. The WANPort configuration form should now be added.
· RAS Name: SiteA
5.Create an IP Route:
The IP Address is the network address of the remote end. Under Destination select the Service created above.
6.Create a new Line:
The Line Number and Line Group ID must be unique, in other words, not used by any other line. The Gateway IP
Address is the IP Address of the Control Unit at the remote end. The Compression Mode used is dependent on the
Voice Compression Card the Control Unit is running and the speed of the link.
7.Create a Short Code:
To route all calls where the number dialed starts with 8 via Line Group ID 1, therefore via the VPN Line created above.
· Short Code: 8N
· Telephone Number: N
· Line Group ID: 1
· Feature: Dial
At Site B on IP address 192.168.45.1
1.Repeat the above steps for VoIP traffic from Site B to Site A.
