Unified Addressing
A single SIP AOR (address of record) provides a unifying iden-
tifier that can be used for routing all communication to a
user. Simply put, an AOR allows for a single user identity to
be mapped across multiple devices so that people connect
with people, without needing to know which devices they
have and are presently using.
This address eliminates the need for tracking users’ multiple
phone numbers, e-mail addresses, and IM contact names.
Turn to Part 3 for the scoop on AOR.
Operational Cost Savings
SIP trunks are IP trunks from service providers that use SIP
for call control and routing, enabling enterprises to create a
single, pure IP connection to carrier clouds. Voice traverses
the network just like other IP applications.
SIP trunks reduce operational costs by enabling the enter-
prise to eliminate hardware, software, and recurring network
charges associated with using traditional PSTN trunks for
voice communications. If you’re keen on cutting costs, you
can find out more in Part 4.
Simplified Communications
Architecture
At the foundation of SIP’s philosophy is the concept that intel-
ligence should reside in the endpoint. This concept is evident
in SIP’s native ability to support peer-to-peer communications.
Peer-to-peer environments don’t rely on communications
servers, gateways, or other intermediate devices to support
communications between users.
Peer-to-peer SIP networks are easy to set up and administer
yet can include features such as automated attendant, voice
mail, and three-party conferencing. This architecture is best
exemplified by Avaya’s Quick Edition solutions. We explain
this in detail in Parts 4 and 6.
