[Serusers] RTPProxy issues with G729 at different frame lengths

If I set my UA (which is behind a NAT Firewall) to use 10ms frames with
the G729 codec, there is one way audio from the UA to the PSTN. The
PSTN gateway has a public IP Address. If I use any other codec (e.g.
gsm, uLaw) there is no problem - the audio works both ways. If I use
G729 with 40ms frames, there is also no issue - it works perfectly.
Becasue the UA is behind a NAT, I am forcing rtp proxy use, but as this
works with codecs other than G729 with 10ms frames, I don't think that
this could be the issue. My question is anyone else seeing this issue,
or conversely does anyone else have this working?
