MAC addresses
The IP Softphone 2050 default IP address comes from your Ethernet
hardware, as a Medium Access Control (MAC) address. If several
Ethernet interfaces are installed, then the IP Softphone 2050 chooses the
first MAC address it detects and uses that address in all subsequent re-
connections.
Note: Some Virtual Private Network (VPN) clients hide their MAC
addresses. In this case, you must override the default value to
prevent problems communicating with the server.
