And unfortunately ekigia is not a decent relacement. As for pidgin, forget it. Maybe it will use a laptop built in cam, but it don't see my usb cam that has no probs with skype..
I have made Ekiga work... However  I also have the advantage of running a 
VoIP service that I can run it through... (Which I understand the folks 
behind Ekiga now do too). The issue has always been (and alway will be) 
NAT. It's hard to get 2 SIP devices, each behind NAT to talk to each other 
successfully. Skype achieves it - most of the time - by only using one 
channel for communication. SIP needs more than 1.
Using an external registrar (such as an asterisk box hosted on a public IP 
address) can make things easier, but then that remote server carries all 
your data - more "Internet" for your data to go over... However this is 
the way I've had most success with my commercial VoIP services. It's hard 
to take out the third party, even though it's something fully supported by 
SIP (it was designed to work like that), due to the issues with NAT.
The other issue with Ekiga is codecs - Ekiga to Ekiga is fine, but Ekiga 
to a videophone is rubbish with H263 - all that Ekiga supports as H263 is
"free", but if you want quality, then you need H264 - and there are 
patches/libraries for Ekiga to support the non-free H264, but...
