Just remember that if you're using iLBC with IAX2 trunking, that you'll
want to set the trunkfreq to 30ms instead of 20ms.  Otherwise, you'll
have iLBC packets jumping in and out of your trunk, and you'll wonder
why the bandwidth is higher than it should be.

(Wasn't it you John that first figured that out?)

Yes, it certainly is.
