Thanks for all your tips, still no VM. I can't see where to set the SMDI base port you mentioned to the 1st. SLT port. When I dial 250 VM pilot port I see the IVP8 light up port 1 and then status light flashes orange and resets to green. The phone has no dial tone it flashes the 250 and hangs up. I don't hear any message on the phone.
