Voice over IP (VoIP) OpenPhone IPC
Notes
VoIP system telephony requires an active IP connection to a workplace computer.
If a Firewall is installed for your workplace computer, you may need to explicitly
allow this connection.
If you log on to the workplace computer using a different user name, you must
reconfigure these values.
You can use any arbitrary sequence of digits not already in use in the LAN for the
device ID. Select a random device ID to secure telephone usage. The device ID can
only be read on the Web console.
The displayed menu texts and parts of the operations software are elements of the
OpenPhone IPC installation, but they can be loaded from the OpenCom 510 via
TFTP. where necessary
