Hi guys, Lately I've been getting a network busy, call dismissed error over and over again. It was originally just every once in a while, but now it is getting more frequent. SMS and data seem to work fine when this is happening. I tried wiping cache and dalvik when it was happening but that didn't seem to help. Is this an issue with sprint's network or is it more likely my phone. I'm running fresh evo 4.3.3 with the stock kernel, radio is 2.15.00.0808, pri is 2.15_003 and prl is 60683. Any advice would be appreciated. Also, I couldn't receive any calls while this happened either.
