Hi
I am have some difficulties using the latest RTPProxy. Everything seems
to work fine unless you use G729 codec with 10ms frame lengths. Has
anyone else experienced this issue, and does anyone have any suggestions
to work around the issue?
Kind Regards
Noel

You are going to need to provide more details about what is wrong. This
is just to vague.

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?

I just tried it using a PAP2 in my office and it works fine with 10ms
frames (confirmed using Ethereal). Maybe your gateway is the one that
does not like 10ms G729 frames. Why don't you try a call between 2 UAs
using the rtpproxy to verify.
Cheers.
