Media RTP/RTCP to/from Legacy
Note
Port range is configurable.
Vidyo recommends
configuring 20 ports per call.
Therefore for expected
capacity of 50 calls, plan so
that the Min Port is at least
1,000 less than the Max Port.
The following diagram illustrates the call flow of Legacy and Vidyo desktop users when a
VidyoGateway and VidyoPortal/VidyoRouter are deployed in a DMZ environment.
These are the additional port requirements between the VidyoGateway and the
VidyoPortal/VidyoRouter:
