Earlier today, I went to eBay and typed "VoIP" into the Search box. Just to see what I'd find. I am curious that way.
My Search found 462 results.
The cheapest of these were a long string of one-cent offers of everything from free routers to one month of free IP Telephony service.
I clicked on one of several such "one month free" eBay posts from VoIP services provider iPhone. If you buy in via eBay, they'll send you an e-coupon that you can use to sign up for service.
Would you sign up for an offer via an eBay offer? Let me know by posting a TalkBack.
