I have a customer that recently migrated all their Nortel Meridian users to Unity voicemail through a PIMG. They had conducted a test pilot that went very well but have discovered an issue affecting about 20 out of 800 users, which includes the president & vice-president. For these 20 users, the Nortel as "DDGD" enabled which, from my understanding, blocks the caller ID from being displayed. This creates 2 problems - the first is that when unanswered calls are forwarded to the Unity server for any of these users, Unity does not know where to route the call to. The second is that when any user tries to check their messages, again, Unity does not know where to route the call to, so both of these types of calls are dumped to a general mailbox.
Does anybody have any recommendations on how I can work around this issue? I am familiar with CCM/Unity, but very limited on Nortel Meridian knowledge.
Thanks in advance,
