It is inside the zaptel driver and is initialized by chan_ss7 to 4 * 160 bytes (80ms) You can increase it to some other multiple of 160, but it requires a recompile, and will also increase the audio-delay. I've once read about an algorithm to a dynamic jitterbuffer, which whould "expand" itself when it runs full, and shrink after some time. Maybe it would be a good idea to make some experimental implementations of such a buffer.. Mvh. Jacob -- Jacob Tinning System Developer SIFIRA A/S
