I had this happem to me as well with the initial install. Go back into the config and delete out the missed calls option and I think it may fix it. Also if you could give a little write up as to how you got it working correctly I would appreciate it. I have not been able to get it going agian as you can read from my previous posts.

(sms and missed calls included by default, only sms is required) (voicemails, recent calls, received calls, etc. can also be added)
