[asterisk-dev] Jitter Buffer

As of Revision 45678 there is a small patch that makes it work with
jbforce=yes.

However, as far as I can tell it never works unless you force it.

So for example:

PSTN (T1 via Zap) <-> Asterisk 1.4b3 <-> Voip Device

The Asterisk <-> Voip Device leg never gets jitter buffer unless
forced. 

And yes I'm talking about the received audio at the Asterisk side. It is
not dejittered.
