I should have done an executive summary:
Where a channel is native bridged to another iax2 channel:
1) Lag is not measured and will usually show 0ms. Any other number is an
old measurement from the start of the call
2) The jitter buffer on this machine is not used. Any
jitter/jitterbuffer measurement shown is left over from the start of
the call.
