titleFirewall Test Results

Introduction: Firewall test checks if outbound communication to the LiveVox application ports is permitted by your network devices. 

Info
iconfalse

Outbound communication to the LiveVox application ports is required for the platform to function correctly. Blocked ports may result in the loss or degradation of service.

Objective: Ports are not blocked.

Test: In the Firewall Results section of the email, check if the ports are reported as blocked.

Issue Resolution: If the ports are reported as blocked, contact the LiveVox Customer Care Team.

The following table describes the use of each port.

PortUse
TCP 443Web traffic (HTTPS).
TCP 8080WebRTC traffic (web and audio paths established simultaneously).
UDP 5060SIP-Trunks when your PBX does not support encryption with TLS version 1.2.
TCP 5061SIP-Trunks when your PBX supports encryption with TLS version 1.2. Also used for sLVC (99.9% of clients use the Secured accounts). 
TCP 5071sLVT (hard-phones supported: Polycom VVX-310 and SoundPoint-331).
UDP 15000-30000RTP streams (audio).



Note

A blocked port can be considered to be the cause of an issue depending on how you have implemented the port (that is, how you have established the audio path). For example, if you are establishing the audio path via WebRTC and the test result shows that the port TCP 5061 is blocked but TCP 8080 is enabled, this is not the cause of the issue.


Warning

If you are asked to enable a port, ensure that the port is enabled only in the outbound direction.

  2. Send the results of the commands to LiveVox.
