The Acme Roller Skates Company has its corporate HQ in Seattle, with remote sales offices in Denver, Chicago, New York, and Atlanta. The company is in the process of transitioning the H.320 videoconferencing system to an IP videoconferencing system. The company has installed an MCU at the corporate HQ, but the remote offices still have 320 terminal endpoints. A Cisco IPVC 3526 PRI Videoconferencing Gateway has been installed to allow the remote offices to dial into videoconferences. The telephony provider has given the company a block of 100 phone numbers for the PRI, which can route to all the channels on the PRI. Which method will be best for routing calls from the gateway to the MCU or other endpoints?
The Acme Snowboards Company is planning to install an IP videoconferencing system. Up to 10 vendors need to participate in weekly videoconferences using H.320 video endpoints at 128 kbps.

Cisco IPVC 3526 Videoconferencing gateway
User A and User B are in a video call using Cisco VT Advantage. The call was set up via the local Cisco CallManager. User A and User B determine that they need to add User C to the call. User A attempts to conference in User C, but there are no more SCCP ports available on the MCU. What will be the outcome of the conference attempt?
The conference will proceed, but only audio will be available.
A customer has deployed a centralized call-processing model in the organization. The customer would now like to deploy a Cisco VT Advantage camera on each IP phone to facilitate video calls and videoconferences.
