What is ‘Multiple Points of Presence’?
Multiple points of presence (MPOP) is a concept in networking and communications applications that a user can be present at different communications methods at the same time. This is an advancement on the traditional Single Point of Presence.
For example, a person might be present at a computer, a desk phone, and a mobile phone at the same time.
MPOP is supported by many unified communications applications such as Microsoft Lync.
Many communications programs, such as instant messaging clients, can report presence information, such as whether a user is available, away or busy. With the move toward unified communications in the enterprise, presence can get more complicated. A user might be unavailable at a desk phone but reachable by mobile phone.
With a single point of presence, a user is only available in one place at a time, but with multiple points of presence, users can be reachable by multiple contact methods at once.
