Looks like you arevery familiar withthe state of SMS in FusionPBX, and you're just fishing.
Would be redundant for me to link you the rest of the SMS related threads on this site, so what have you tried?
Might help people give you a useful answer.
Nice! Thanks! I'll check them out.Check out Skyetel and their PostCard platform. Skyetel is awesome and built an open source messaging server. You can download it and check out more from their site.
We also have built a sample .Net Windows based client application that can do mass sms using the Skyetel API if your interested.
