Thank you very kindly for your email. We have identified the cause of this issue and are working diligently to resolve it for you. We can offer you a temporary workaround in the interim. Please disable the outbound Caller Id Block and your voicemail "should" stop asking for the area code and phone number. This has been found not to work on ALL units so if this still fails, please know we will have this resolved for you very soon.
Thank you for your patience and understanding in this matter.
