dejitter buffer on IP phones

[abulatkin]

Hi,

I've tried to find info on dejitter buffers on Cisco IP phone but couldn't. Does anyone know how big is that buffer and if it is adaptive or configurabe? What is the max size of that buffer.

The 7940 and 7960 phones have a non-adjustable, adaptive jitter buffer that can hold up to 1000ms (1 second) of audio.

I know all the other Cisco phones have adaptive jitter buffers, but I don't have any data on their size.
