When you call HG 160 from any phone voicemail does pickup. Usually goes to 161, 162, etc in order.

When you press the programmed button with CA160A99, voicemail answers, but fails to dial A99, which is my PSD. If you program button to dial CA161A99, voicemail answers and then dials A99, works fine. Some issue when programming CA160 where 160 is the pilot of the group 161-168. 160 will not forward digits to PSD.
