Flowroute SMS Support

I believe this was requested already but I want to bring it up again. It would be hugely beneficial to have Flowroute supported as an SMS provider. I have moved over a dozen of my clients to VitalPBX but am restricted on moving many of them because the vast majority of my clients require SMS and their SIP trunking is through Flowroute. Having support for SMS would enable me move nearly all my clients to VitalPBX.
