Hi,
DP300 has built-in MCU but it is governed by the license. You need license to use it. DP300 can provide following functionalities with the help of built-in MCU:
Using the endpoint that has a built-in MCU, users can call multiple sites one by one, or use a predefined conference template to call multiple sites at a time. After a conference starts, sites can dial the number or IP address of the endpoint that houses the built-in MCU to join in the conference.
Maximum connected sites allowed by a non-encrypted conference: 4 720p 30 fps video sites (local site included) + 3 audio sites
Maximum connected sites allowed by an encrypted conference: 4 720p 30 fps video sites (local site included)
Maximum bandwidth required for a conference: 3 Mbit/s (1 Mbit/s for each video site)
One conference can be simultaneously joined by different types of endpoints, including SD terminals, HD terminals, VoIP terminals, H.323 terminals, SIP terminals, and terminals supporting different audio and video formats and bandwidths.
Continuous presence per port: Supports a maximum of 4 video panes.
Supports rich functions, including voice activation, floor request, and dual-stream transmission through H.239 and Binary Floor Control Protocol (BFCP). Can be used in conjunction with Huawei RSE6500 to support multipoint conference recording, meeting the requirements of small- and medium-sized enterprises in terms of equipment price and maintenance costs.
