ABSTRACT:
A control device attached to both a primary packet device (such as a PC-based packet phone) and a network (e.g., telephone network or packet network) provides improved reliability for packet telephony and network maintenance. The control device may have its own network address separate from that of the packet telephony device. The control device enables monitoring of the operation of the packet telephony device and basic maintenance, such as re-booting of that device if it is no longer responding to input commands.
