I have seen it in Linuxworld t ostel's booth. It is actually very close to (but bigger) the design I suggested in the list a couple of days ago. Beside long boot time a and huge memory, it seems to be running fine. The huge memory requirement is probably what drives the cost this high.

Linux ensures that custom firmware is a piece of cake. It actually makes pulling one feature out and putting another in as easy as on you computer. It is matter of adding a .so file and an executable to your filesystem. Switching stacks is as easy as killing one process and starting another. I have been working on a linux phone that used to be vxWorks and linux gives my unlimited flexibility. Custom firmware is a nightmare (and using a nowhere compiler like I have seen suggested here) and a huge can of worms.

[Asterisk-Users] Little patch for packetization in G729 in chan_h323
I cannot see how this code does anything at all. There are two sides to my channel driver, the Asterisk side and the H.323 side. The configuration is in the Asterisk side. Since you defined the int g729Frames =8 in the Asterisk side, you would need to pass that value to the H.323 side. Did you actually check the value of g729Frames in ast_h323.cpp before calling g729aCap->SetTxFramesInPacket(g729Frames); ?

[Asterisk-Users] Little patch for packetization in G729 in chan_h323
Hi
I have hacked this patch to make G729/chan_h323 work with most other
platforms, all it does is let me set the packetization interval. It
defaults to 24 which is way too high for me and even though it should
work but does not for some reason and after connecting the voice coming
from asterisk is really bad (oversampled??). This lets you set the
packetization to your choice (I use a value between 2 to 8) by putting
"g729Frames=<number>" in the h323.conf. For me g729Frames=2
works pretty
good.
I am getting really good quality with G729 now, (this is the codec I
bought from digium)> And it is a G729AnnexA codec.
Apply it to latest CVS by (should apply fine to older ones too)
