I have been testing, as a newbie, some voip applications/providers. First, Skype on both Linux and Windows, and everything was working fine most of the time. Then I have been trying the SIP applications. Me and a friend of mine (in two different european locations, both with DSL) have registered first both with sipphone.com and then both on babble.net, using X-lite on both sides, or X-lite and Kphone, or Kphone and the babble software. And in all cases, although we were able to establish a phone connection, the voice quality was not enough good to have a conversation (we could hear some vocal sounds, but nothing else). In the case of babble it is pretty strange, as I am able to make phone call through it (using X-lite or Kphone, DSL or even an analog modem) to normal telephones. But I have never succeeded in making pc-to-pc calls. Can anybody suggest me how to solve this strange thing, or at least how to go in the right direction to solve it?
pc-to-pc voip: unsuccessful so far

Do you or the receiving party have a router (i.e. Linksys router?). If so, you'll need to open some ports up to allow for incoming connections.
99% sure not (100% sure on my side of the connection)
Start with a simple test using an ethernet without the Internet. A
cross-over cable, or a small hub/switch will do. Ignore SIP
registration, and just call to the phone number at the other IP
address (on your same subnet).
For example:
- First PC running softphone at extension 100 on IP 192.168.1.100
- Second PC running softphone at extension 101 on IP 192.168.1.101
- First PC calls sip:101@192.168.1.101
- Second PC should "ring"; then you answer, talk, hang-up
- Second PC calls sip:100@192.168.1.100
- First PC should "ring"; then you answer, talk, hang-up
Once you get the above running, then try fancy stuff like routing
across the internet. At least then you will know you have a base
level of function (and how good or bad your audio sounds :-).
