Inventors:

Michael Hugh McClung - Ruckersville VA, US
Robert D. Corley - Plano TX, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04Q 7/00
H04L 12/28
H04B 7/212

US Classification:

370329, 370341, 370356, 370348

Abstract:

A method for implementing a virtual line channel in a packet switched network includes reserving a virtual line channel associated with a first station and establishing a communication session between the first station and a second station over the virtual line channel. The reservation of the virtual line channel is maintained while the communication session is active. The communication session may be transferred to a different channel associated with a third station. The reservation of the virtual line channel is maintained while the communication session is active despite the transfer of the communication session. When the communication session has terminated, the reservation of the virtual line channel is released.

Appl. No.:

11/173032

Inventors:

Michael H. McClung - Ruckersville VA, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04W 4/00
H04B 1/40

US Classification:

4554261, 455 741

Abstract:

A method for providing communication service includes detecting that a wireless handset has been decoupled from a base, wherein the base is associated with a plurality of communication addresses.

Appl. No.:

11/512532

Inventors:

Michael McClung - Ruckersville VA, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04M 3/42

US Classification:

37920101, 379260, 709238, 715753, 715758

Abstract:

Techniques for voice instant messaging (VIM) on a programmable telephone set include receiving configuration data that includes VIM ID data that indicates a particular group of telephone sets. A start signal is received that indicates a start of a new message directed to the particular telephone set over a particular communication channel associated with the VIM ID. In response, VIM audio data received over the communication channel is recorded. It is determined whether the particular telephone set is currently in use. If not, then the VIM audio data is played over a speaker on the particular telephone set. These techniques allow instant, persistent audio messages to multiple recipients without a computer.
