The new jitterbuffer

You must add "jitterbuffer=yes" to either the [general] part of iax.conf, or to a peer or a user. (just like the old jitterbuffer). Also, you can set "maxjitterbuffer=n", which puts a hard-limit on the size of the jitterbuffer of "n milliseconds". It is not necessary to have the new jitterbuffer on both sides of a call; it works on the receive side only.
