Dear des0906
I (and my engineers) am serving approx. 200 customers with the old type VMX-100/200/300 sytems in a small country in Europe.
Based on our country's population this number of OCTEL/VMX customers is high, as the prices for a new system years ago was very very high.
We recommend the users / customers to keep their existing OCTEL/VMX-100/200/300 systems as long as possible, as it is.
The reason for this is that these systems are extremely reliable.
The customers, of course, buys new and PC based voice mail servers for their VIP employees. These VIP employees often require Microsoft Outlook or Lotus Notes e-mail integration, and a graphic interface on their client PC to operate their voice mailbox.
The companies now have two voice mail systems. The old VMX for the basic users requiring a telephone interface (touch tone telephone) and the users requiring a GUI interface (Graphic User Interface), i.e. a PC.
In the end, I think, both user types are happy and the companies save on money, not having to "upgrade" all their users to the PC based voice mail systems.
Best regards doktor
