Maybe, see below.

No.  Only echo test (500) is suboptimal.

I think no.

I think no.

I think the problem is because:
- either pulse; in last unstable release, ekiga is finally provided with 
a ptlib plugin for pulse, this should solve this issue in my opinion (I 
have not tested, but it is a plugin expecially for pulse) - this last 
version is not as usable as 3.2.x release, we are preparing it, but it 
might take more time
- or because G.722 and G.711 audio plugins are not well supported in 
ekiga; I advise to use speex
- or your sound card is sub-optimal

Well, I think this is an issue in very special cases, not in the case of 
this person.
