I've tried both G.729 and alaw.
Like a magic, it works very fine!
The audio quality is good, and there is no sensible delay
after half an hour of conversation.

So it may be a codec problem only occur to G.723.1.

I also tried mixed codec situation, say
A uses G.723.1 and B use G.729.
A can hear clear audio from B, but
B hears choppy sound.

The problem was independent of the channel types.
(I used SIP, H.323 and MGCP)

BTW, my G.723.1 and G.729 codec are from Intel IPP library.

I decided to file a report to Mantis:

Hopefully it can be fixed before 1.2.0 release.
