do show iax2 channels during the call to see how large the jitter/lag
is. Some of the calls I get need a 750 sized jitter buffer. However, if
it gets that bad you need to look at the route the call is making and
maybe choose a provider with less lag. It is also essential that your
provider is using a recent version of *.
