Israel at it again: Here Comes Dynamic Caller ID
Flat Planet Phone Co., an Israeli VoIP startup, has developed a new VoIP technology called Dynamic Caller ID that essentially allows you to have multiple caller IDs built on the fly.
These caller IDs depend on the local number being dialed.
For instance, if you call someone in Orange County, Calif., from New York, the recipient would only see the local number on their handset.
The same holds true when making calls to about 50 countries, FPPC claims.
