Tested. And not good news ;-(

I managed to place a call with Ekiga with my usual SIP account and using 
the integrated mic/speakers from the netbook and it works... but sadly 
the overall sound was simply terrible, unusuable to keep a conversation.

Thinking the problem could be the bad quality of the sound card, I 
attached my usual Plantronics USB headset, which was detected by the 
system without problems but still the call sound was very bad (very 
cranky with a loud background sound).

I'm starting to think the problem can be Ekiga itself, because using the 
same SIP account, with the same headset, going out from the same DSL 
router and calling the same phone number, in my Lenny system this setup 
works very well but in Wheezy is impossible to use.

In brief: consider testing a different SIP/VOIP program.

Google suggests using "jackd" to get this working (mic going through 
speakers) among other solutions but I don't know if it's worth the 
effort. In the end, what's your goal for having this?

It works on my side but as I already told you, is almost unusable. I 
don't know if Ekiga is the one to blame here but trying with a different 
softphone won't neither hurt.

I have in my radar "Jitsi" (https://jitsi.org/), it was an application 
I've been following very close because I like the fact it's written in 
Java thus can be used also from a windows system, although still not 
tested :-P

Sure. And what is worse, now there is no way to tell Ekiga what input/
output hardware device to choose, it has to be done from the GNOME sound 
applet first :-/
