Your client is correct.  Configurable packetization was added
introduced with the release of 1.4.0.  For details look at the
rtp-packetization.txt file in the doc directory for full details.

The short answer is to append :<size> to any codec on your allow
directive that you want to change from the default of 20ms.
Ex.
Allow=g729:40
