As
Internet Telephony is gaining huge popularity day by day, SIP
trunking is becoming a widely discussed issue in the world of Unified
Communications and a lot of people are eager to be better informed
about this new technology and the advantages it offers. In order to
achieve this goal, we decided to write an article which will answer
to your main questions concerning SIP trunking.
What is SIP ?
SIP stands for the Session
Initiation Protocol. It is a signaling communications protocol,
widely used for controlling multimedia communication sessions such as
voice and video calls over Internet Protocol (IP) networks.
What is a SIP provider?
A
SIP provider is any telecommunications company which provides SIP
Trunking to customers, usually businesses.
What is SIP trunking?
Unlike
in traditional telephony, where bundles of physical wires were once
delivered from the service provider to a business, a SIP trunk allows
a company to replace these traditional fixed Public Switched
Telephony Network (PSTN) lines with PSTN connectivity via a SIP
trunking service. In addition to VoIP
calls,
SIP trunks can also carry instant messages, multimedia conferences,
user presence information and so on.
How can I deploy SIP
Trunking?
A
SIP trunk can connect your organization to an ITSP through either an
IP-PBX or a Mediation Server. A Mediation Server performs encrypting,
decrypting, and data translation between an Office Communications
Server deployment on one side and the world beyond on the other.
