All the OBi ATAs have 8 Voice Gateway accounts that can be used to set up other providers that allows outgoing calls without registration
. This Voice Gateway cannot accept incoming calls, only outgoing!

That sounds similar to what I'm thinking as well...
...but how is she using three providers with the OBi110? (GV, Anveo, and CallCentric?) I think it only supports 2 providers.
