The Ports page (Admin > Settings > Ports) allows you to control which networking resources the system will utilize when communicating with the outside IP world. When specifying ports, list the ports that you may bind to, either specifying a port number or explicitly specifying the IP address and the port, separated by a colon (e.g., 192.168.1.2:8080). If you are binding to IPv6 addresses, you must put a square bracket around the IP address (e.g., [2001:db8::4]:5060). If you are only specifying the port number, the system will bind to all IPv4 and IPv6 addresses on the system. If you want to bind only to IPv4 sockets, use the form 0.0.0.0:5060. If you want to bind only to IPv6 sockets, you can use [::]:5060. In general, you may bind to more than one socket; just separate the addresses by spaces. If you do not want to use the service, leave the field empty. If you change a port binding, you will need to restart the snom ONE service. We support the default SIP port.
Changes to HTTP and SIP settings require a system restart.
