For information on specifying ports in the VidyoGateway, see "Configuring HTTPS Port Settings for
Your VidyoGateway Admin Pages" on page 126.
The following diagram illustrates the port requirements between VidyoGateway cluster nodes.
Cluster Node
Port requirements between the VidyoGateway cluster nodes.
Port(s) Type
694 UDP
Description
Secure connection to VidyoPortal
(https:).
Note
VidyoRouter session control (SCIP).
VidyoManager (EMCP).
Media stream (H.264 SVC) to
VidyoRouter
Note
Active
VidyoGateway Cluster
UDP 694: Heartbeat
UDP 1719: H.323 gatekeeper registration
TCP 1720: H.323 call setup
UDP 5060: SIP call signaling
UDP 17190: H.323 call signaling for active controller
TCP 17200: H.323 call signaling for active controller
TCP 49999: Inter-cluster secure channel
UDP 50600: SIP call signaling for the active controller
Description
Heartbeat between the cluster
controllers
Required for Vidyo Encryption.
Therefore if this port is open, no
need for port 80
Port range is configurable. Vidyo
recommends configuring 50 ports
per call. Therefore for expected
capacity of 50 concurrent calls,
plan so that the Min Port is at least
2,500 less than the Max Port.
