Found one interesting issue: I had sent epage a PM about onering failing to connect.

I have setup OneRing as well as Gtalk in my VOIP and IM settings.
It seems that OneRing has connection problems if Gtalk connects before it.

If OneRing claims to have "Network connectivity" errors, then the workaround is to disable gtalk, sign in OneRing and then re-enable gtalk.

gtalk doesnt seem to mind that it comes in second.
