magicJack and magicJack Plus Support, Reviews, FAQs and Tricks

Does that pretty much bomb this entire forum, if you cannot do anything with MJ outside of the USB dongle?

I'll +1 that. I'm in the same boat; I recently bought a second-hand RTP300 locked to Vonage, and I Rooted it successfully, and would love to use it as an SPA for MagicJack, if that's still possible. If not, I'm happy to take suggestions for another SIP service that is on the cheap!
