As far as the above is concerned I have the following:

I am using Asterisk 1.2.10, patched with this patch for 1.2.10.  I have 2 * boxes.  They call each 
other over SIP, and I have in sip.conf on both boxes

autoframing=yes
disallow=all
allow=g729:80

When A calls B, it sets ptime:80.

On B I see this:
We're at 192.168.0.64 port 11004
Adding codec 0x100 (g729) to SDP
Sep  7 18:16:16 WARNING[5529]: frame.c:1072 ast_codec_pref_getsize: Framing not set for codec g729, 
using default 20

and ptime:20

So B is setting packetization to 20, when it should be 80, and is not respecting autoframing.

I have tried this with reinvites=yes and no, and autoframing=yes and no, still the same.
