1. A telecommunications method, comprising:
- setting a jitter buffer occupancy threshold;
receiving data into a jitter buffer; and
adjusting a depth of said jitter buffer if said jitter buffer occupancy threshold is crossed, said adjusting comprising increasing or decreasing periods of silence.

Abstract
A jitter buffer controller allows the depth of the jitter buffer to be adjusted dynamically according to the varying jitter of the current sequence. The contents of the jitter buffer are examined during a transmission. If the delay or average delay within the buffer drops to a predetermined threshold, then the size or depth of the jitter buffer is increased.
