In this type of deployment, the signaling call flow for video calls goes through the IP Office. The RTP media of the video stream does not go through the IP Office if direct media is appropriately set up on the IP Office. If the WAN connection between the branch and the center is lost, the video endpoints are still connected to the IP Office. Video calls to other sites will not be possible if the WAN is disconnected, but local video calls within the branch or audio-only calls to the PSTN through the IP Office can still be made. For more information about connecting the video endpoints to IP Office, see IP Office: Avaya Scopia® Installation Notes.

IP Office video endpoints registered to IP Office in the branch can have video calls with the headquarters or other sites of the enterprise. You can use these endpoints to make and receive video calls to and from any of the following:

• A video multipoint control unit (MCU) located centrally such as in the headquarters, which is connected via the central Avaya Aura® Session Manager.
• A video endpoint registered to the central Session Manager.
• A video endpoint registered to an IP Office in another branch, which is connected via the central Session Manager

In a typical branch deployment using this option, the video endpoint is deployed within the branch and connected through the WAN to the central Avaya Aura® infrastructure. In this deployment option, IP Office is not involved in either the signaling or the media flow between the video endpoint in the branch and endpoints in other sites. If the WAN connection between the branch and the center is lost, the video endpoints do not receive service. Failover of these endpoints to IP Office is not supported.
