I have had the same issue with mine, and I transferred numbers directly from the phone. It shows the pauses in the number, but when I assigned it to a speeddial position and I try dialing it, it only dials the number, and my voicemail system just waits for input.

I am stumped. There are two different ones available when you enter the numbers manually into the phonebook - "pause" and "wait". Neither of them seem to work.
