Vocera Voice Server IP Ports

The IP port usage information required for Vocera Voice Server is provided in a table format.

Keep the following ports open for effective communications between the source and destination processes.
Important: By default, the signaling gateway ports are dynamically assigned to allow clients to connect. If your organization’s firewall set up blocks clients from connecting with the signaling gateway’s randomly selected ports, you can specify a value for signaling gateway ports (TCP, UDP, and DTLS) in the application.properties file. You can find this file in the following directory: {vocera_drive}/vocera/signalinggateway). Contact Vocera Technical Support to implement any customizations to the application.properties file.
