About once a week my DX phone stops working right... It will not make an outgoing call - at least it seems to not complete the call. But I now believe it does ring the called phone, but they can't hear me and I can't hear them. Also, while this failure is occuring, my phone WILL ring for an incoming call, but when I answer they can't hear me and I can't hear them. Turning the phone off and back on does not help. Removing the battery for 10 second and restarting does fix it - until next week. I've heard of others with this problem who had their phones replacesd. Is that the only real solution??
