What Is SIP Trunking?

Traditional phone calls go over phone lines, but with the rise of the internet, Voice Over IP communication systems give you much more functionality to receive a high volume of calls. This is called SIP (session initiated protocol) trunking. These services are offered by the majority of VoIP providers and can be tailor made to suit the needs of a small business all the way up to a large corporation with a gigantic workforce and everything in between.

One of the main advantages of going with SIP trunking is that it will integrate everything from data, the internet, your video, and your voice services all into a single line. The term "trunking" is a bit dated and goes back to a time when traditional telephone services were used and it described how a wide variety of telephone users could share a much smaller pool of communication paths, thus making it a much more efficient option for businesses than getting a separate phone line for each worker. That was in the past, though, as today's SIP trunking capabilities will even allow all calls to be considered local calls and won't even require the business to have a single phone line at all.

The Benefits of Using SIP Trunking Services

Choosing to use a good SIP trunking service will significantly level the playing field for smaller business to compete with large corporations and appear much more professional and bigger than they actually are. For larger business, one of the main advantages is being able to much more easily maintain that local presence. Regardless of the size of the business itself, SIP trunking's biggest benefit overall is simply the reduction in cost to the company's overall expenses. This is particularly true for SIP VoIP services that are specifically crafted for a business in particular.
  • It offers very low cost calling.
  • It's much easier to scale than other options, making it very future proof.
  • SIP trunking makes moving a breeze, as you can easily take your phone number with you while moving offices or even while traveling.
  • Network outages are much less impactful, as incoming calls can easily be routed to other locations.
  • It's ideal for any sized business with at least 25 physical phones.
  • It's a fantastic choice for any business that has an international location.
  • It offers the same sort of emergency usages and will even offer enhanced 911 dialing options.

How SIP Trunking Can Take Your Business To The Next Level

It used to be that you had to have a PRI (Primary Rate Interface) in order to have video, voice, and data all on a single line. This was a physical device that had to be purchased separately but along with your chosen phone provider's calling plans. This is no longer the case with SIP, as it allows your provider to set up a proxy server (commonly referred to as a SIP proxy), which will provide the outgoing, incoming, and PBX calls for you. Everything is located off site and handled by a professional IT team or contractor through your provider, meaning it saves you a ton of time and money on the technical support side of the equation.

Being temporarily shut down means simply having the SIP reroute calls to a different office and also allows you to much more easily outsource to international locations, such as with customer service centers.

All of these benefits are much better than what traditional PSTN (public switched telephone network) have been able to provide through their services and will give your business just what it needs to take it to the next level.

A VoIP is basically a computer network that is adapted to deal with voice calls. Therefore, like any other computer network, it can be hacked. There are a lot of factors that increase the vulnerability of the business VoIP system. One such factor is the connectivity of the VoIP system. Here, ‘connectivity’ refers to the way the network is connected. If the calls are routed to you via the public internet, then the risks are significantly higher. If the VoIP provider is offering you a directly managed IP line straight to your premises and all the calls are routed to you using that line, then the risks are much lower.

Security Tips that You Should Follow

There are a few security measures you should take to make your VoIP network less vulnerable to attacks. Some of the measures that you can take include
Use the Latest in Security Features
A number of coding technologies are used to encrypt the data communicated through a VoIP system. You should check with your service provider about the kind of security features that they offer.

IP White listing

IP white listing is the process which would allow your network to accept calls from only the trusted IP addresses. However, you would need to have a static IP address for all your destinations. If your business is located in the US and you cater to mainly US customers, then you can block large chunks of IP addresses from outside of the US.
