So, I'm new here so forgive me if I missed something else that answers this. My nexus s 4g just recently was resurrected to be used with Ting. So far so good. Today in an attempt to be cheaper(yes I know I should've left well enough alone), I installed sipdroid, got it to set up the google voice Pbxes account. It worked fine for making calls and receiving them to my google voice account. Now if someone calls my ting number it rings on their end and goes to voice mail. Never rings on my end. I've changed my google account password, deleted both pbxes accounts I had and removed sipdroid from my phone. Still not ringing on my end. Done profile and prl updates in the vain hope that'd fix it. I'm at a loss and clearly in over my head and have learned a valuable lesson. If it can be fixed I'd be very grateful for any help. Thanks in advance.
