Configuration of Loopback Interface

What differentiates this solution over previous methods for SIP connection is that this solution provides

the highest level of security available for ShoreTel customers wanting to use SIP trunks with ShoreTel

over the public Internet.

To that end, the solution requires the configuration of a VPN tunnel from the NetVanta device to the

EtherSpeak edge.

Physical Connections required:

1. Ethernet 0/1 needs to be plugged into the customer router and the customer needs to

provide an available public IP address

2. Ethernet 0/0 is disabled to ensure the highest level of security. At the customer‟s option,

this interface may be enabled for LAN access to the NetVanta router

3. PRI port is connected to ShoreTel PRI switch (e.g. 220T1) with a T1 cross-over cable
