• ProCall Meetings license
  allows authorized and licensed users to create and manage meeting rooms 
• Licensing via UCConnect
• Licensing is per user

Further notes on licensing

A ProCall Meetings license allows the user to create and manage meeting rooms.

Invite guests

• Invited meeting participants (guests) do not require a license.

Infrastructure

• ProCall Enterprise installation connected to a UCConnect server account

Equipment for participants

PC, laptop, modern mobile phone, modern tablet, etc. with internet access and a web browser with access to

(depending on communication actions)

• Camera (webcam/external/integrated)
• Microphone or headset

There is no release of the software in the terminal server environment.

The hardware must be recognized and controllable by the browser used.

Supported web browsers

Web browsers with WebRTC support

For example, current versions of

Technical requirements

Infrastructure

Available hosts and ports:

• *.meetings.procall.de 443 TLS
• *.meetings.procall.de 20000-40000 UDP (media to media server)
• ICE STUN/TURN over 80/443 UDP/TCP/TLS is optionally available for the client browser

Table

Restrictions

No web proxy is supported on the UCServer for the connection to UCConnect. This must be bypassed for the connection.

For the clients, it is not recommended that the connection to the services takes place via a web proxy or via a VPN connection. This can lead to limitations in the accessibility of the services and quality within meetings.

Please check with the system administrator if you are connecting to the Internet using VPN or a web proxy. You can also optionally use the following websites for this purpose:

• http://amibehindavpn.com/

Maximum bandwidth video 

transmit: max. 2500 kB/sec
receive: (2-20 participants): maximum per participant 2500 kB/sec
Codec: VP8

Maximum bandwidth audio 

transmit: max. 50 kB/sec
receive: (2-20 participants): maximum per participant 50 kB/sec
Codec: Opus

Maximum bandwidth desktop sharing 

transmit: max. 2500 kB/sec
receive: max. 2500 kB/sec
Codec: VP8

These specifications are maximum values determined under laboratory conditions. The actual values depend on factors such as currently available bandwidth, available CPU, additional screen sharing requirements, or other applications.

CPU/GPU requirements

For the best possible meeting experience, use a modern CPU/GPU that supports hardware acceleration in encoding/decoding of the VP8 video codec. Otherwise, the performance of the overall system can suffer due to software encoding/decoding.

The necessary technical information about the performance of your CPU/GPU can be found in the designated documentation.
A listing for Intel CPUs can also be found in Wikipedia: https://en.wikipedia.org/wiki/Intel_Quick_Sync_Video#Hardware_decoding_and_encoding

Scalability

Maximum meeting participants: 50

It is irrelevant whether a video is transmitted or only audio.
