SIP (Session Initiation Protocol) trunking involves using
VoIP (Voice over IP) to get the connection of a PBX (Private Branch Exchange)
to the internet. When connection is successful, the internet usually replaces
the conventional telephone trunk, which allows an enterprise to communicate
with mobile and fixed telephone subscribers all over the world. SIP is a
standard that initiates user sessions for interactive multimedia, while a trunk
is a link or line that carries many signals at the same time to facilitate
connection to major switching centers and nodes in a communication system. SIP
can be used for presence updates, conferencing, instant messages, and real-time
services that traverse the SIP trunk. The SIP trunk is similar to the circuit
switch but it is different because its connection describes a virtual
connection.
SIP (Session Initiation Protocol) trunking can be a very big
step that will allow you to simplify the telecommunications of your organization.
With this, you have the chance of making substantial savings while preparing
for the latest enhancements in real-time communication. Enterprises should have
an Internet Telephony Service Provider (ITSP) and a PBX connected to internal
end users to make sure that it takes advantage of SIP trunking. Apart from
that, the enterprise should have a gateway that provides an interface between
the PBX and the ITSP. Many enterprises are in a position to benefit from SIP
trunking because of its ability to combine data, video and voice in one line.
This gets rid of the need to have physical media for the different modes.
Therefore, enterprises can enjoy enhanced reliability of multimedia services
and reduce the overall costs. Click here to learn more about data services.
You have the chance of saving costs on long distance
services with the help of SIP trunk connection. You have the chance of
eliminating IP-PSTN gateways and their complexities and attendant costs with the
help of SIP trunks because they are directly connected to your ITSP. You can
eliminate the redundancy of using many telephone and data networks because SIP
trunking provides you with a single IP- based network. Deploying SIP trunking provider allows
you to receive and initiate local calls and long-distance calls, make emergency
calls, access directory assistance, use mobile and fixed telephone sets, browse
the internet and employ texting and e-mail.
It through an IP-PBX or a mediation server that an SIP trunk
connects your enterprise to an ITSP. A mediation server performs data
translation, decrypting and encrypting. The mediation server has both internal
and external interfaces. The external interface is referred to as the gateway
interface. You need to make sure that you determine the connection that you
should use for your SIP trunk. It is over the internet or over a line that is
dedicated to your enterprise that you can deploy SIP (Session Initiation
Protocol) trunking. You may or may not share your bandwidth with other IP
traffic. There is provision of high reliability and security by the dedicated
line even though it costs more. Another type of SIP trunking connection might
be suitable for your enterprise if it has fewer requirements for availability
and security or has lower call volumes.
