tkc9789, depending where you're calling Justvoip has great rates.
There is a solution for your skype problems, I myself have Skype on 24/7 without a PC, OBI110, one phone attached.
I have the Philips voip841 which is a (Skype) coordless Base Station phone system. I hooked that BS to the router and to the OBI110 phone port, if you have a land line hook that one up to the line port of the OBI110.
So in retrospect you have access to skype in/out, google voice, landline and any voip provider all through one phone handset.
Hope this helps you out..
Good luck.
