TANDBERG TANDBERG and Cisco CallManager

D13907.01

4.1 Registering a TANDBERG H.323 endpoint to the CallManager

Some H.323 endpoints (including TANDBERG) have the option of registering directly to Cisco

CallManager and utilize CallManager to provide Gatekeeper/H.323 control functionality; a suitable

configuration for those networks with a small endpoint install-base. This type of solution allows for the

endpoints’ E.164 alias to be fully integrated into the telephony dial-plan. However, there are several

disadvantages when registering an endpoint directly with CallManager when compared to registering the

systems with a fully functional H.323 gatekeeper. The Cisco CallManager only supports H.323 version 2,

and because of this several of the features used in professional video meetings will be lost in a call

between two H.323 units that are registered to the Cisco CallManager.

For example, any call involving these endpoints will not be able to utilize expanded functionality such as

TANDERG Duo Video, H.239, H.235 encryption, H.264, high quality audio (AAC-LD) and high video

resolutions like 448P. Additioanlly, it will not be possible to use most of H323 infrastructure products

available, as CallManager does not support registration of these devices including the TANDBERG

gateway, MCU and MPS. It is because of these limitations that it is recommended to integrate an H.323

gatekeeper into CallManager through the creation of an H.323 trunk in CallManager. The integration of

an H.323 gatekeeper will allow communication between H.323 and SCCP endpoints as well as provide the

ability for the H.323 endpoints to implement all of the advanced features such as encryption, H.239 and

others.

However, if a direct registration from the MXP endpoint to CallManager is desired, a few settings will

need to be configured properly within the MXP endpoint in order to ensure compatibility between the two

systems. Using the TANDBERG remote control navigate to Control Panel > Administrator Settings >

Network > LAN Settings > H.323 Settings and select CallManager for H323 Call Setup, go into the

CallManager settings and enter the IP address of the CallManager. For more information about the

TANDBERG MXP endpoints see the TANDBERG MXP User Manual.

Note: Because CallManager is not a Gatekeeper the endpoints will not get any feedback on the

TANDBERG MXP that it is registered, and the unit will not show its e.164 alias in the top of the screen as

it does when it is registered to a gatekeeper
