Calls Gizmo Project sound even better than Skype?
Is Gizmo Project a Skype Killer? For those of you not in the know, there are now two programs out there that do free P2P VoIP - Skype has been around for quite awhile now, where Gizmo Project (which may get a new name soon) is a relative newcomer.
Both offer similar paid services, such as the ability to call out to standard phone networks, or the ability to have your own custom inbound number.

My friend asked me if I knew how they compared, in terms of RAM utilization. Skype.exe is eating 22,784K according to Windows XP. Gizmo.exe is using 16,292K. Gizmo wins for size, at least initially, but is still beta and has less functions now.
Any call to a Gizmo Project user is free. No matter when, no matter where, no matter how long. Free. There?s no monthly service charge. Nor is there a set up cost. Gizmo Project is free.
