After sever calls to Sprint Tech support trying to figure out why all phones on my account could place calls through the Airave except my Moto Photon to no avail and great frustration I figured it out myself. For some reason with Google Voice enabled on my line I can receive calls and use data but can not place calls. Disabled GV and low and behold it works great.
I sure wish Sprint could have figured this out before I did a Master reset!
I hope this may be of use to someone with the same issue.
