It's NOT that simple. You get a nanoBTS and it needs to connect to an MSC (IP.Access also make a MSC, though it will connect to others). An MSC is a mobile switching centre, which is effectively a telco switch running SS7 protocols. There also needs to be an HLR (home location register) which maintains information about the mobile. When in coverage of the nanoBTS you'd need to manually get your phone to connect to a non-preferred network (i.e. to the network ID of the BTS) or issue your own SIM. The nanoBTS is just a small part of running a GSM network and is not functional by itself. If you did connect to the BTS, then it would send the call to the MSC which would have to connect to a telephone network. This would all be manual, if you want to do things with other GSM networks you need roaming agreements etc (i.e. automatically handing calls off between your regular GSM network and your own network), but basically you're running a COMPLETE GSM network. Depending on where you're based, there are also spectrum issues as to run a BTS (i.e. GSM network) you need a license to operate in those bands.
