I have a customer who is having problems transfering calls directly to VM. It seems to be a frequent problem which is happening on both of the operators phones, just never when I'm around. VM seems to be answering because ext number comes up on the display and after dialing the ext number displays call transfered. The call just seems to be put on hold and never does go into the mailbox. It is a MICS with NAM VM. They have a T1 and 1 analog line going into the system and the problem happens on both. The only way to get the call to go when it happens is to transfer to the ext and the call is forwarded after the designated number of rings. Any Suggestions??
