What Ports do I need to open for VoIP phones?
Last Updated 2 years ago
3.x -
The following are the ports that might need to be opened on your firewall to allow 3.x operation:
1. HTTP - port 80 to reach the webUI.
2. SIP - port 5060 to communicate between phone and server. (Can be different depending on the configuration, this is just the common port)
3.SSH - port 22 - probably will not be needed but can be used for remote administration.
4. TFTP provisioning - open common TFTP port (69). HTTP and HTTPS will use 80 and 443 respectively
5. RTP port can be configured at phone (will apply after reboot for 040 firmware). The default currently is 20000. You will need to open a range of ports if required by the PBX.
