How Can SIP Trunking Benefit Your Business?

Woman answering a call on a flower shopHave you heard of SIP and what it is used for? Session Initiated Protocol (SIP) is a protocol most commonly used in 3G telephony. Also known as VoIP communications, it allows users to communicate through voice and video calls for free on the internet.

According to SIP.US, SIP trunk has the same functions as traditional analog phone lines — but with a twist. Instead of using physical wires, it uses the internet to connect phone systems. Mostly, businesses that need multiple phone lines for their employees use this technology.

Benefits of Converting to SIP Trunking

Think about the use of traditional analog phone lines. A business owner would need to connect all his employees to the Public Switched Telephone Network (PSTN) individually.

SIP trunks remove the need for the complex IP-PSTN gateways and its corresponding costs. SIP trunks allow you to use the same IP network connection for a particular bandwidth that you can choose to increase in small increments based on your needs. This removes the need to purchase in blocks of 24 or 32. You only pay for the trunks you need. This also means it’s easier to scale up or down depending on your business needs. Most SIP trunk providers would even allow a bunch of connected phones to a single PBX or key system. Offices can also make savings on telecommunication costs, especially on long distance calls.

Considerations

SIP trunking is great, but there are still some considerations you need to think about. When you use SIP for your phone lines, you are putting your phone system on the internet. This admittedly is not the safest place to be without proper precautions. So, you need to make sure that you have the right firewall installed. Avoid malicious attacks, such as theft and fraud.

SIP trunks eat bandwidth. So the more phone calls your employees make, the more data bandwidth you need. Verify with your SIP provider that their service is compatible with your IP PBX and if they support fax.

In Summary

SIP trunking can significantly reduce your telecommunication costs. You only need to pay for the trunks you need. However, there are certain things that you need to take into consideration. These include security, how much bandwidth your business needs, and the compatibility of your infrastructure with your SIP provider.
