TANDBERG TANDBERG and Cisco CallManager

D13907.01

6 TANDBERG Expressway and Cisco CallManager

The TANDBERG Expressway solution is an enabling technology that will allow H.323 endpoints to

securely traverse a firewall. The TANDBERG Border Controller is the key component of this technology

by serving as the traversal server within the solution. Using the TANDBERG Border Controller in

conjunction with the TANDBERG Gatekeeper will allow endpoints that don’t support the Expressway

technology to traverse a Firewall.

By implementing the Border Controller on a network, all SCCP endpoints can make use of the traversal

technology through integration with a TANDBERG gatekeeper and complete H.323 calls with endpoints

outside of the local firewall. To make use of the Expressway solution, CallManager must first be

configured to register an H.225 trunk to the gatekeeper. Expressway will then be utilized as part of the

normal H.323 network deployment.

When connecting a call from an SCCP endpoint to an H.323 endpoint outside the network, call setup will

first go through CallManager, to the TANDBERG Gatekeeper, through the Border Controller to the

endpoint outside the firewall. For more information on the TANDBERG Expressway, reference

documents D13381 TANDBERG Gatekeeper and D13691 TANDBERG Border Controller user manual.

Figure 8 show an illustration of the SCCP and H.323 network with an Expressway solution to traverse a

firewall.
