can join a conference hosted in the private network via the traversal server if there is an open

connection through the firewall.

A dedicated Avaya Equinox H.323 Edge offers external endpoints a static address when

joining conferences hosted in your organization. You can dial 1234@pathfinder.company.com

to access from outside the firewall, or you can dial 1234 directly if you deployed the Avaya

Equinox H.323 Edge Client.

Configure the Avaya Equinox H.323 Edge as the XT Series's gatekeeper and enable H.460.

• Using the XT Series for NAT and firewall traversal

In cases where your organization has no sophisticated firewall protection, the XT Series can

straddle the two network zones using the both network ports provided on the XT Codec Unit

(see

Figure 9: Using XT Series for NAT and Firewall Traversal on page 30).

Activate the second network port

with the correct license, then connect one port to the

public network and the other to your private network. All communication passes through the XT

Series which acts as the virtual conference room for all the endpoints.

A gatekeeper allows the XT Series to dial aliases instead of IP addresses for endpoints in the

private network, while for public endpoints, you must dial IP addresses. Without a gatekeeper,

all endpoints must be referenced using IP addresses.
