No 3G/LTE calling option, can't make outbound calls. – phone.systems pbx mobile client Review

Gentlemen, it's 2015 and your app is crippled to only WiFi or PSTN calling. Charge a few bucks and give the option of g729 and calling over cellular data. Also, after working with support was never able to get this app to dial out. I ended up using another SIP app to make calls. Fix the auth!
