; The jitter buffer's function is to compensate for varying

; There are presently two jitterbuffer implementations available for Asterisk
; and chan_iax2; the classic and the new, channel/application independent
; implementation. These are controlled at compile-time. The new jitterbuffer
; additionally has support for PLC which greatly improves quality as the
; jitterbuffer adapts size, and in compensating for lost packets.

; maxjitterinterps: the maximum number of interpolation frames the jitterbuffer

; indicate silence, the jitterbuffer will assume silence has begun after

; maxexcessbuffer: If conditions improve after a period of high jitter,
