Suddenly after installing IOS 7.0.3 I'm having trouble reaching my company voicemail. I have the access number, pauses and pin codes stored in a speed dial favorite. The iPhone dials the number just fine, then pauses but when it comes time to dial the pin code apparently it's doing it too fast or something because the company system responds with a message saying the pin code is invalid. When I dial all numbers manually there's no problem at all. Any idea what I can do to fix this so I don't have to manually dial all those numbers to access my company voicemail? Thanks very much.
