There’s no question that the onset of the Internet has changed the world — especially the world of business communications. Phone systems that were once limited to copper wire connections now have the ability to connect via the Internet. This progression of phone connections has allowed organizations to communicate better with customers, save money and take advantage of the latest features. This capability is possible because of SIP.
What is SIP?
SIP stands for Session Initiation Protocol, and is defined as a signaling protocol that carries voice and data. SIP was designed to evolve the needs of IP communications to support the features and call processing functions of the public switch telephone network. Sam Price, product manager at TelNet Worldwide explains the details about SIP.
To understand how SIP works, let’s compare it to a traditional phone call. When you conduct a phone call, you dial a number to reach someone. With SIP, you reach someone through a universal resource identifier or URI, which will identify the call.
There is a common misconception that there are differences between VoIP and SIP. In actuality, you can think of VoIP as an overarching umbrella of telecommunications solutions, while SIP falls underneath that umbrella, according to Price.
You might have heard that SIP has a bad reputation, thought to be a complicated service. But in all reality, SIP is very basic in technicality and very rich in functionality. Examples of features include:
• E911 service and call forwarding. E911, short for Enhanced 911, is a way to alert emergency services not only for help, but to direct them to your exact location as well, according to Price.
• Call Forwarding Busy - Redirects a call when there’s a busy signal
• Call Forwarding Not Reachable - Redirects a call in case a phone number is unreachable
• Call Forwarding Always - Redirects all calls to a different number
• Call Forwarding No Answer - Redirects a call when there’s no answer
SIP Trunking allows voice and data to be connected between two points in order to enable ‘cloud calling’. “This provides a connection between our session border controller through the Internet, to your PBX,” says Price.
Benefits of SIP Trunking
1. Cost Savings
With traditional wireline based services (PRI, for instance), you are purchasing 23 voice channels, when you may only need 12. This means that even if you’re only using a portion of your lines, you still are paying for all of them. With SIP Trunking, you can customize the number of lines for your business, which means you’re paying for exactly what you need and saving money.
Whether you need to add 1 or 10 phone lines, SIP makes additional line installation simple and completely customizable. And as your company grows, we’ll configure additional SIP call paths on your existing Internet connection.
3. No Hardware
Speaking of hardware, no longer do you have to worry about any bulky PRI equipment. “With SIP, it’s totally cloud-based, so there isn't any additional gear taking up space in your closet,” says Price.
4. Business Continuity
Built-in ‘Call Forward Unreachable,’ our business continuity feature, enables you to automatically redirect your calls to another phone or location in the event of severe weather, fire or a line cut, so business can continue no matter what.
5. Unified Network
Manage your data and voice traffic over a single IP network with ease. Since SIP is a cloud-based solution, it’s easy to implement upgrades and new IP-based features across all your business locations.
