SIP Trunking: An Overview

in Business-continuity

SIP trunking uses PBX to let companies to utilise VoIP as well as other real-time communication methods. The SIP trunk can be connected with a conventional telephony network, permitting companies to speak with people outside of the local network by IP technology. SIP trunking allows all communications to traverse a single gateway - enhancing the stability of the connection, and reducing costs. This is excellent for business continuity, and makes unified communications technology affordable for every size of business.

SIP Trunking: How Exactly Does it Operate?
SIP Trunking works by combining voice and data communications into something which can be done over one single line. Via SIP trunking, the data network can carry voice traffic, and a link is generated in between the legacy voice line, and the firm's Internet connection.

To illustrate how trunking performs, imagine that a member of staff located in Seattle makes a call to head office in Nevada, using the office telephony system. According to the precise system used, the call either stems as an Internet protocol call or changes to one as the call is made. It then drops down to the PSTN once it gets to its destination. Why is this all worthwhile? Simply because the call cost is only a small portion of a typical long-distance phone call. These savings really can mount up for companies that produce a lot of long-distance calls.

What Does SIP Trunking Mean for Business Continuity?
As long as your SIP trunk is set up correctly, it is normally more dependable than, for instance, an ordinary ISDN connection. The most important factor here though, if you want to boost your business continuity, is to be sure that the SIP trunk is set up properly. You will need a direct link to your trunk provider if you want to guarantee stability. Additionally, you'll require some sort of failover connection. If you aren't positive whether SIP is designed for you, there are hybrid solutions available.

Making the Shift to SIP Trunking
There's an up-front cost to adopting SIP Trunking. This is to pay for a direct link with your trunk provider. Without it your call quality will suffer. You will also need to purchase a SIP gateway. However, when the link is set up, you should start seeing financial savings pretty rapidly, as your data connection will be less expensive, as will your line rental, and your phone calls.

Thinking long-term you'll make even more cost savings, particularly if your company evolves. As opposed to ISDN lines, which are limited to 30 channels per circuit, SIP is totally scalable. Therefore, however many new employees you employ, you won't need to cover the cost of extra phone lines.

This scalability is fantastic for small firms, because they do not have to dedicate themselves to a service that they'll quickly outgrow, or invest in technology that's beyond what they need, just in case they need it in the future.
