 Hah, didn't know Skype was p2p, I always thought it was also going through

Skype can at its own discretion decide to use your connection to route traffic 
of
somebody else.

Ekiga, I think, has adjustable jitter buffer, which sometimes really improves
quality at the expense of latency.

Skype uses pretty wide band codec; Ekiga gives you a choice, so bandwidth can
be better utilized.

  Sergei.

In skype you've no control on number of connections it makes to other
nodes, nor how much bandwith it takes up; and skype's streams are encrypted,
which means longer drops may occur in case of channel congestion.
Moreover, if all goes 'well', your instance may act as a 'supernode' hence 
taking most of your bw.  In some situations, all the rest been equal, such 
cases may lead to poor performance on the channel you're talking.

There are likely other possible explanations for what you see, these are
just a few points.
