Beats Solo 2 Wireless headphones on call no audio?

Hello,I was wondering if anyone has this kind of problem.
everything works fine with Music,Facebook calls,Skype calls or any other online social media app except when it comes to SMS Call? so if someone called in i pick up i can't hear any audio or anything from them? I've checked my firmware for both on my Iphone 5s and my Beats Solo2 Wireless and they're both up to date.If anyone has a solution to this please help me.Thank you!
