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

Port number	Transport	Direction	Host	Purpose
443	TLS	out	(*.)meetings.procall.de	ProCall Meetings services, such as the web front-end
20000-40000	UDP	out	*.meetings.procall.de	Media in/out to the media server
443	UDP	out	*.meetings.procall.de	STUN requests to determine the public IP address of the client
443	UDP/TCP/TLS	out	*.meetings.procall.de	Media Relay via TURN
443	TLS	out	*.ucconnect.de	Connection of the UCServer to UCConnect and login of the client browser via UCConnect at the UCServer

A detailed list of hostnames and IP addresses of online services for firewall configuration can be found here.

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:

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
