• 10.0

Unified MP users can choose Cisco WebEx as the web conferencing provider when scheduling a Unified MP meeting. Cisco WebEx integration is available in Cisco Unified MP 6.0.2 and later releases. Voice and video conferencing are provided by Unified MP. Voice and video dial-in information must be provided to WebEx users in order for them to join the meeting, or they can use the out-dial feature that is available in WebEx to join the meeting.

You can use any standards-based audio endpoint that connects to Cisco Unified Communications Manager to join a WebEx meeting. The supported audio endpoints include the Cisco IP Phones, Telepresence endpoints, and PSTN devices such as mobile phones and land line phones. Many audio endpoints support audio and video connectivity. However, only audio connectivity to the Cisco WebEx Meetings Server is supported.

To permit users from outside the organization to join WebEx meetings by using PSTN devices, your company must deploy Analog-to-VoIP Gateways, such as Cisco Integrated Service Routers (ISR). The IP phones listed below have been tested with Cisco WebEx Meetings Server:

• Cisco 7960
