After several months of experiencing this problem and it being fixed for specific numbers, it's still a problem as recent as today. It's very frustrating to not be able to complete the call. One thing I noticed
with one of the numbers I called today is that it did ring more than once prior to disconnecting. It rang approx. 6 times and then disconnected so I guess that's "progress", but the end result is the same;
it disconnects. I used my cell phone as I now know I have to do when this happens. Today I asked the person I attempted to call, if the phone rang previously. I was told it never rang although on my end, it rang several times prior to disconnecting. On another attempt to another number, it reached the persons v-mail and then disconnected during their outgoing msg. This is a problem with both local and long distance calls. There needs to be a permanent resolution to this problem.
