Mr. Roboto. ;allow=gsm ; Always allow GSM, it's cool :) ; ; You can adjust several parameters relating to the jitter buffer. ; The jitter buffer's function is to compensate for varying ; network delay. ; ; All the jitter buffer settings are in milliseconds. ; The jitter buffer works for INCOMING audio - the outbound audio ; will be dejittered by the jitter buffer at the other end. ; ; jitterbuffer=yes|no: global default as to whether you want ; the jitter buffer at all. ; ; forcejitterbuffer=yes|no: in the ideal world, when we bridge VoIP channels ; we don't want to do jitterbuffering on the switch, since the endpoints ; can each handle this. However, some endpoints may have poor jitterbuffers ; themselves, so this option will force * to always jitterbuffer, even in this ; case. ; ; maxjitterbuffer: a maximum size for the jitter buffer. ; Setting a reasonable maximum here will prevent the call delay ; from rising to silly values in extreme situations; you'll hear ; SOMETHING, even though it will be jittery. ; ; resyncthreshold: when the jitterbuffer notices a significant change in delay ; that continues over a few frames, it will resync, assuming that the change in ; delay was caused by a timestamping mix-up. The threshold for noticing a ; change in delay is measured as twice the measured jitter plus this resync ; threshold. ; Resyncing can be disabled by setting this parameter to -1. ; ; maxjitterinterps: the maximum number of interpolation frames the jitterbuffer ; should return in a row. Since some clients do not send CNG/DTX frames to ; indicate silence, the jitterbuffer will assume silence has begun after ; returning this many interpolations. This prevents interpolating throughout ; a long silence. ; jitterbuffer=no forcejitterbuffer=no ;maxjitterbuffer=1000 ;maxjitterinterps=10 ;resyncthreshold=1000 ;trunkfreq=20 ; How frequently to send trunk msgs (in ms) ; Should we send timestamps for the individual sub-frames within trunk frames? ; There is a small bandwidth use for these (less than 1kbps/call), but they ; ensure that frame timestamps get sent end-to-end properly.
