Introduction

Voice Enhanced AppWans have the capability to provide Layer 2 network connectivity that transport layer 2 traffic (vs TCP/UDP IP layer3/4) from client to gateway. This presents a “flat” network in which all the clients and the gateway can communicate as if they are on a Layer 2 switch. The gateway bridges all this traffic to the network which it is on and bridges traffic among the clients. This opens the capability to utilize VOIP systems infrastructures (and many other networking applications) that require the end client IP addresses to be reachable across networks. 

This article states how a user can create their Voice Enhanced AppWAN.

Creating your Voice Enhanced AppWAN Components

Create Voice Enhanced Gateway

Go to Manage Gateways and click on the Blue Plus Icon. From there you will see a list of different types of Gateways, click on the Voice Enhanced Gateway tile.

Enter your Gateway attributes and click Create.

Create Voice Enhanced Service

Next, you'll need to go to Manage Services and click on the Blue Plus Icon. This will bring you to another list of tiles, click on the Voice Enhanced Service tile.

On the next screen, you will need to enter your service attributes and choose your Voice Enhanced Gateway from the dropdown. A couple notes here:

1. The bridge interface will always be 'br0' for Voice Enhanced Services.
2. Your VLAN number needs to be between 1 and 1024 and cannot be reused on other services.

Create Voice Enhanced AppWan 

After clicking Create, you will need to go to Manage AppWANs and click the Blue Plus Icon. Then click on the Voice Enhanced AppWAN tile.

Add Client Endpoints to utilize the Voice Enhanced Service

Here you can enter your groups, clients, and service that you need attached to this AppWAN.  Please keep in mind that a Voice Enhanced AppWAN can only have one service and that service must be a Voice Enhanced Service. After clicking Create, you have completed your Voice Enhanced AppWAN.

Clients can participate in Voice Enhanced AppWans and Standard AppWans.    

Additional Network Setup Notes

1. There should be a DHCP server setup by the customer to manage Voice Enhanced AppWan client IP addresses/network space.  Each Client is assigned an IP Address for use on the Customer Network via the Voice Enhanced (Layer 2 ) Network.   When registered/online and part of a Voice Enhanced AppWan, the client PC is allocated a Network Interface to operate on the Voice Enhanced (Layer 2) network space.  This Network Interface is assigned an IP Address via the Customer DHCP server.

2. The Voice Enhanced Networking Service IP address space should not conflict with existing client’s IP addresses assigned to client PC.   Conflict of IP address will cause the Voice Enhanced (Layer 2/3) and user normal IP traffic to route to undesired places.

3. On a mixed Voice Enhanced Service (Networking Layer 2) and Standard Service (Networking Layer 3/4)  setup, the Standard Service (Networking Layer 3/4) intercept should not conflict with the space assigned for the Voice Enhanced Service (DHCP Assigned Voice Enhanced Client IP address). Also any  Standard (Layer 3/4) services should not have transparent mode turned on.
