Disambiguation
This document describes Multiple Address Appearance (MAA) for
OpenStage@Asterisk. The Telecommunication Industry Association (TIA) has defined
terms for VoIP telephony features [1] which slightly differ from the Siemens
Enterprise Communications (SEN) wording. This has historical reasons. As SEN uses
the terms consistently in every kind of documentation, this document will also use
the SEN wording. The following terms are affected:
Multiple Address Appearance (MAA)
Multiple Line Appearance (MLA)
Multiple Station Appearance (MSA)
The following table gives an overview about the differences:

The Multiple Address Appearance feature, also commonly
known as "Multiple Line Appearance", provides the served user
with multiple addresses appearing on a single telephone. The
served user has the ability to originate, receive and otherwise
control calls on each of these address appearances. These
address appearances behave independently of each other. MAA/

type Multiple Station Appearance provides the ability for the same
address (e.g. telephone number, DNS name, URL) to appear on
multiple telephones. Users at each telephone may be provided
with the ability to make, answer, share and otherwise
manipulate calls on the affected telephones. MLA /

The main difference is the usage of the term “Multiple Line Appearance”; SEN uses
MLA for MSA too, whereas TIA uses MLA together with MAA.
