SIP Trunk
SIP, short for Session Initiation Protocol, is an
application layer protocol that lets you run your phone
system over an internet connection instead of traditional
phone lines. Trunking refers to the backbone of phone lines
used by multiple users that connects to a telephone
network.
SIP Trunks provision Voice over Internet Protocol
(VoIP) connectivity between an on-premise phone system and
the public switched telephone network, also known as PSTN.
For instance, an office might have an existing PBX for
phone service. SIP trunks provide phone service for the
entire office so they can reach the outside world.
It operates similar to HTTP, which is the very
basis of browsing web pages on the internet. SIP was
embraced by the open-source community and acted as a
catalyst for commercial phone service. Also, SIP's
capabilities extend beyond phone service, into broader
messaging functions.
An excellent SIP trunking service lets you use
your existing PBX equipment to transition into an
internet-powered telephone network.
And thatâs not all: you can also use a SIP phone
as part of your unified communications system. You can
synchronize all your communication channels in real-time.
This way, you'll enhance productivity, collaboration, and
efficiency across your company.
What is SIP Trunking Used For?
The main role of SIP trunking is to replace PRI technology.
PRI, or Primary Rate Interface, has been used for decades
to deliver lines of voice and data using physical copper
lines. Essentially, it's a bundle of analog phone lines put
together. PRI can be costly to maintain since the hardware
is becoming outdated rather quickly.
With SIP trunking, this happens using VoIP
technology. SIP also supports other data like instant
messages and video conferencing.
SIP trunking is the right choice for any office, who is ready
to move their business communication on a light budget.
