Hi, Does anybody know how exactly the jitter buffer in the zap channels work? Is it adaptive or fixed? ; Configure jitter buffers in zapata (each one is 20ms, default is 4) ; jitterbuffers=30 This setting puts 600ms of jitter buffer but the call does not sound as if it had a .6 second delay which leads me to believe the buffer is adaptive. If so, can I hardcode it to be fixed? Thanks, -- Andres Technical Support http://www.telesip.net
