Abstract
A system and method for implementing telephony devices in a distributed network environment is disclosed. The present invention provides for checking data packets to ensure that non-voice data packets are properly tagged to be transmitted on a native virtual local area network (“VLAN”). Voice data packets transmitted on a separate VLAN with a higher priority.

27. A system for ensuring data packet tag integrity, the system comprising:
-
a network switch; and
at least one telephony device coupled to the network switch, the at least one telephony device operable to;
receive a message from the network switch to check contents of incoming data packets;
check the contents of the incoming data packets; and
re-mark virtual local area network information of the incoming data packets with one of a plurality of virtual local area network tags based on the contents of the incoming data packets in response to the message received from the network switch. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)

35. A system for ensuring data packet tag integrity, the system comprising:
-
a network switch; and
a first telephony device coupled to the network switch, the first telephony device operable to;
receive a message from the network switch to check contents of incoming data packets;
check the contents of the incoming data packets; and
re-mark virtual local area network information of the incoming data packets with one of a plurality of virtual local area network tags based on the contents of the incoming data packets in response to the message received from the network switch.

36. A system for ensuring data packet tag integrity, the system comprising:
-
means for switching data packets; and
telephony means for transmitting and receiving voice and non-voice communications, the telephony means coupled to the means for switching, the telephony means operable to;
receive a message from the means for switching to check contents of incoming data packets;
check the contents of the incoming data packets; and
re-mark virtual local area network information of the incoming data packets with one of a plurality of virtual local area network tags based on the contents of the incoming data packets in response to the message received from the means for switching.

37. A method for ensuring data packet tag integrity, the method comprising:
-
receiving a message at a first telephony device that switches the first telephony device between first and second modes of operation;
checking contents of incoming data packets if in the first mode of operation; and
re-marking the incoming data packets virtual local area network information with a tag for one of a plurality of virtual local area networks according to the contents of the incoming data packets if in the first mode of operation. - View Dependent Claims (38, 39)
