Don’t delete it — save it on your computer for possible future needs, with GotVoice.
Why save them? Well, maybe you need a backup on your PC of someone violating a restraining order by calling you.
Or you need proof to e-mail to other people about a political robocall.
Well, GotVoice lets you do that.
No, I haven’t tried it yet. But Democratic bloggers trying to fight the GOP fakery in many states of calling under the name of the Democratic congressional candidate — doing 6-7 repeat faked calls to try to get people mad at Democrats — suggest GotVoice is a great way to have proof to e-mail to local newspapers, local TV stations, cable news stations, etc.
Oh, the beta version of GotVoice is free, too.
