Patent ID: 8861405

Claim:
A method of dynamically switching between sampling rates for a plurality of conferenced voice channels in a telecommunication system including a telephony side, a network side, and a conferencing unit between said telephony side and said network side, comprising: detecting a presence of a switching stimuli during conferencing between said plurality of conferenced voice channels; identifying at least a first affected voice channel by said switching stimuli from said plurality of conferenced voice channels; responsive to said switching stimuli, based on a telephony side sampling rate of said first affected voice channel, a network side sampling rate of said first affected voice channel, and respective sampling rate of others of said plurality of conferenced voice channels, determining whether or not to switch a sampling rate for at least said first affected voice channel using a switching criteria; provided said determining indicates to switch, switching said sampling rate to a different sampling rate for at least said first affected voice channel; and identifying, by a control and switch logic, a selected group of upsamplers and downsamplers in at least said first affected voice channel to be either enabled or disabled, wherein said switching of said sampling rate is implemented by enabling or disabling said selected group upsamplers or downsamplers.
