SIP Trunking (Session Initiation Protocol) is the virtual equivalent of a traditional business phone line - a SIP trunk is a virtual connection to the Public Switched Telephone Network (PSTN), utilizing your internet connection. The term "trunking" itself dates back to the original days of telephone service. A trunk was a shared communication path for a large number of telephone users. SIP itself is one of the specific protocols that enable VoIP services to work. While traditional phones use physical lines and circuits to connect to the PSTN, a SIP trunk replaces the physical connections with virtual connections over your existing IP networks. Because information is transmitted through the internet and not landline telephone lines, SIP integrates voice, video data and internet services into one single line. With the invention of VoIP and PBX, voice communications were no longer restricted to traditional circuits and landline phones. Instead through SIP, a signaling language designed to carry data like voice, video and instant messaging, we can utilize the internet to highly cut down on the cost and rigidity of older phone systems. All SIP calk are local calls and you won't even need a phone line. SIP Services are offered by most business VoIP providers for both small and large application, and offer a cost effective https://getvoip.com/sip-trunking/ 4/25/2017 Top SIP Trunking Providers: 2017 Reviews & Pricing I GetVoIP Page 4 of 7 way for small businesses to maintain the professional presence — and for large companies to maintain a local presence. How SIP Trunking Works: SIP trunking delivers your telephone and Unified Communications services over an existing IP network, and replaces your traditional telephone lines. Through a SIP trunk, VoIP users can make calls directly to any phone on the PSTN without telephone lines by connecting to a compatible hosted PBX system. The only three necessary elements to operate a SIP trunk are the SIP Provider that supplies the services, a phone system that has a trunk side to enable SIP, and a border element to facilitate the connection between your enterprise network and the PSTN or an external IP carrier network. These border elements can be a firewall or switch, and are usually managed by your SIP Trunking provider. With only these three simple elements any business can vastly boost its telecommunications reach. A pre existing IP-PBX installed will only make the process even easier. Most Common Advantages of SIP Trunking Services: Thanks to SIP, small businesses can easily appear large and professional with a level of service often reserved for more expensive solutions or Fortune 100 companies, This also makes it easier for a large business to maintain their local presence, as all SIP calls are local calls — customers don't have to dial a generic call center number. Of course, the benefits of SIP don't end there. • SIP's inherent flexibility allows for users to add or even subtract as many phone lines as they need, without the hassle of overpaying for unused lines, or waiting for your phone company to sort it all out. Everything can be handled through dedicated web portals to tailor the phone system to your needs on the fly. • While analog trunks can be disrupted by bad weather and rely on expensive phone companies, SIP trunking can help mitigate disaster scenarios by properly rerouting and prioritizing calls to different networks or phones. • Consolidated hardware and setups reduce the installation and maintenance costs of adding or changing your existing phone system. The system can grow without even adding new hardware, a new trunk for extra phone lines doesn't require any new devices. • Take your phone number with you anywhere you travel or move offices, as your number isn't bound by location. If your primary link to the SIP provider fails or just isn't where you are, any internet connection can serve as a temporary link to your SIP network. • If your business does a lot of calling oversees, SIP can offer free international calls based on your provider and pricing plans (compare industry leading SIP providers above). How SIP Trunking Can Improve Your Business Communication SIP trunking replaces old school styled connections that were just way more limited than IP networks. Adding phone lines required the purchase of a new trunk that included at minimum, 24 additional lines. You may only needed just one additional line, but had to purchase an entire trunk — now you spent more money and have 23 useless lines. One of SIP Trunking's https:/Igetvoip.com/sip-trunking) 4/25/2017 Top SIP Trunking Providers: 2017 Reviews & Pricing I GetVoIP Page 5 of 7 strongest points is its scafabif ity, it will grow painless with your business, or even shrink if your needs change. Because SIP trunking combines video, data and voice all into one single line, your local, long distance, broadband Internet service, and even video calls are all handled through one network. With dynamic bandwidth allocation, you can ensure the necessary resources are available for basic web use, while maintaining a consistent call volume and quality. Not to mention with every service on the same network, the necessary hardware you need in house drops dramatically. No longer will you need in house IT managers just to stay on top of your phone lines, with Sip technology nothing is on -site. Your provider sets up a SIP proxy server to provision incoming, outgoing and PBX calls and they even take care of all technical support to cut down on costs and headaches. Service outages are a thing of the past with SIP trunking. If one location shuts down temporarily, SIP trunks will automatically reroute calls to any other locations and extensions to at least partially restore services. If there is an unexpected power outage, calls can be rerouted to a separate satellite office. Companies with an international presence, or even considering outsourcing, can take advantage of this benefit. The flexibility of SIP trunking allows you to spread staff across the country or even the world. More on How SIP Trunking Will Help Your Business. Why Use SIP Trunking Over Alternative Solutions: By sending all of your data over one single connection, it doesn't take much to start saving money with a SIP trunk. SIP trunks alone are more than 25% cheaper than PRI trunks, and that's before calling rates. Beyond a level of flexibility that just not available in traditional phone services, SIP even allows you to make free voice calls between any offices on the same VoIP system. With a large list of providers and hardware taken care of on their end, pricing and installation costs are much lower, and rates for calls are lower as well. Another option, Primary Rate Interface (PRI) trunking allows for large businesses to transmit a large number of voice and data communications from multiple locations, but is mostly seen as an older, almost outdated alternative to SIP. As it relies on the use of T1 lines, telephone circuits might need to be added and calling fees are generally more expensive. More on SIP vs PRI here. Whereas PR1 trunking can fail in adverse weather, SIP services ensures you will stay connected and automatically reroutes calls as necessary. As an internet-based replacement for traditional phone service, SIP is a central part of how VoIP works and allows fora more robust, and flexible unified communications system. Choosing the Right SIP Trunk Solution: Once you've decided SIP trunking is the right method of connectivity for your business, the most important step is to then choose which SIP provider best fits your needs. • Network — With a lot of provider's simply rebranding SIP trunking service hosted on other provider's networks, it's important to distinguish if the network is hosted and run by your SIP provider directly. Everything is easier without a middleman. https://getvoip.com/sip-trunking/ 4/25/2017 Top SIP Trunking Providers: 2017 Reviews & Pricing 1 GetVoIP Page 6 of 7 « Security — A standard concern for almost any service over the Internet, it's important to ensure the necessary security measures are in place to keep your information safe. With ail of your data transmitted over the Internet you would want your SIP trunk to be secured with a solid, protected network and anti -fraud system in place to monitor any feedback and mitigate any risks. * Number Porting — If you want to keep your existing phone number, make sure your provider is capable of number porting from your specific region. Most services and providers do offer porting, but it can be limited in different regions around the world. • Customer Service — Although SIP Trunking itself does a good job and disaster mitigation, if everything goes down you'll want to make sure you can get ahold of your provider as soon as possible. A five minute outage could quickly turn into a massive, and costly, headache. • Pricing — As with any service, pricing will vary based on different providers and levels of service offered. Of course, you pay for what you get and if you want business -class service you should be prepared to pay respectively. Those rebranding offers tend to be on the cheaper side, but quality might suffer. What is SIP Trunking?
