No, but basically jmp.chat takes over your phone number… it acts as your carrier for voice and SMS (similar to Google Voice). Maybe not exactly what you want.
You can use JMP to communicate with your contacts without them changing anything on their end, just like with any other telephone provider. JMP works wherever you have an Internet connection. JMP can be used alongside, or instead of, a traditional wireless carrier subscription.
The benefit of this is that you can receive voice and text on anything that can serve as a XMPP client.
