I believe this is a flaw with the OS or at least the VZW implementation on the Z10: automated dial strings cannot be implemented. This worked fine on the Storm and Torch.
1. Program a dial string to access our company voice mail system using phone number followed by Pause command then password and other access digits separated by other Pause command.
2. Dial the number
3. Instead of pausing and dialing the other digits, the phone waits until the user hits the green Dial button on screen.
This was a real handy feature for business users - you know, the core audience for BB.
