It is quite disappointing that while the SGS is a great "fun" device it generally fails at the simple task of making cheap voip calls to normal phones. My 4 year old Nokia took five minutes to set up with Skype and Voipcheap and it actually worked. I just spent 4 hours trying to get Voipcheap to work through Sipdroid and Pbxes and generally failed. While incoming calls seem to work, outgoing fail. Extensive googling revealed the problem to be with Voipcheap and possibly the particular server in use at Pbxes. Little wonder, considering Voipcheap are busy coming up with their own mobile solution.
So, is there anything else that works?
