RTP packetization is for RTP based channels, like SIP, and it reduces badwidth by putting multiple 
frames in one packet, so you save *ALOT* on packet headers, and it actually is more efficient.  This 
in not what a trunk in IAX2 is, which is a multiplexed trunk, putting multiple calls in one 'trunk'

So with packetization, if packetization=10 and g729 , your 1 packet contain 100ms of audio, instead 
of 10 packets containing 10ms audio each.  However, dont set tooo high level of packetization, as 
you will be introducing delay.
