Benefits and the 10 Best SIP Trunking Providers for Small Business
The strides in communication brought about by developments in VoIP technology have improved business prospects both locally and globally. Organizations that are keen to manage their telephone bills may benefit from adopting this form of technology. By channelling their calls through SIP trunks business entities may avoid punitive costs.
Such punitive charges and costs are often associated with the plain ordinary telephone system which is copper based and analog. Improvements on this old system came with the introduction of modems, Integrated Digital Services Networks, Digital Subscriber Lines and PBX systems.
SIP trunking is highly scalable due to the fact that it does away with the many physical connections that traditional lines come with. There are numerous benefits that are associated with cloud-based SIP trunking services. This goes beyond providing other alternative options for voice communications.

The technological evolution as relates to communication in the latter part of the 20th Century has impacted businesses and interpersonal communications in more ways than people could ever imagine. This technological revolution has made communication much faster, cheaper and easier to execute than it was during the industrial revolution.
This tremendous shift in the delivery of communication from the industrial revolution to the information age, which is also known as the digital age, have been made possible through innovations and inventions that have improved the delivery of vast amounts of information by the use of computers and telephones over a very short period of time.
To find out more about SIP trunking, how it works and the manner in which it has impacted telephonic communication, keep reading.
What is SIP Trunking?
The acronym SIP stands for Session Initiation Protocol. This is a signaling system that enables electronic devices to communicate through VoIP by managing the elements of a call. The elements of a call that SIP supports include instant messaging, video distribution, video and call conferencing, voice calls and faxing.
To understand how SIP trunking works requires a look at traditional telephony which includes landlines. Traditional telephone systems rely on networks which are operated by switches. Signals are carried along the switches through electrical wires. These signals are analog and mostly transmit voice communications.
SIP trunking on the other hand uses the internet to send unified communications which include integrated services like single number reach and extension mobility, voice and instant messaging. All that is needed for SIP trunking is an internet connection, preferably a Virtual LAN that is meant for SIP trunk calls only.
Simply put, SIP trunking and Voice Over Internet Protocol technologies are one and the same thing. Their capacities to deliver the service is what defines the difference between the two. SIP calling may not be free but is relatively cheaper than the use of landlines for long distance calls. Long distance call fees are essentially eliminated.
History of SIP Trunking
SIP Trunking relies on the use of a telephone or an analog phone line. Without the telephone, VoIP and SIP would be virtually unheard of. It goes without saying that the telephone is part and parcel of SIP. The history of SIP is better understood in retrospect by tracing the invention of the telephone and subsequent changes in telephony.
VoIP communication was made prominent during the 90s but it was first used in the year 1974 when it was piloted through ARPANET. VoIP technology had previously not been made available to individuals and businesses until the year 1995 when the initial VoIP software was crafted for home and personal computers.
The year 1996 was the defining moment in the history of modern telephony when Mark Handley, a computer expert and others including Eve Schooler, Henning Schulzrinne and Jonathan Rosenberg designed the Session Initiation Protocol. This creation formed the basis which SIP trunking would ultimately operate.
Further developments in telephony and the refinement of IP PBX systems and VoIP gateways meant that SIP could support improved voicemail features like voicemail to email. The introduction of DSL and cable towards the millennium improved internet speeds tremendously and led to greater demand for VoIP over traditional analog lines.
How Does SIP Trunking Work?
For SIP trunking to work, there has to be an IP-enabled private branch exchange or PBX system. This system enables users to communicate both externally and internally through various communication media like ISDN and VoIP. SIP connects the private branch exchange hardware to the internet.
The framework that is essential to complete a SIP trunk are VoIP and PBX equipment. With that said, SIP trunks replace Public Switched Telephone Network (PSTN) as a means of transmitting voice signals by applying the use of packet switch network. By this, voice signals are converted into digital packets and conveyed through a network.
SIP channels are held by each SIP trunk. Traditional telephones use wires to transmit both outgoing and incoming signals. A SIP trunk utilizes a SIP channel to facilitate both incoming and outgoing calls. This over-the-internet exchange of information is useful to transmit voice calls and messages from one SIP address to another.
The number of concurrent calls that can be made via SIP trunking is based on the bandwidth capacity of the internet service provider being used. Individuals and businesses that have on-premises PBX systems may contact SIP trunking providers to connect them and allow them to make outbound calls on their existing system.
SIP Trunking Vs VoIP
To know the difference between SIP trunking and VoIP requires a definition of terms to distinguish the two. VoIP uses broadband connections to send calls to the Public Switched Telephone Network. SIP on the other hand is the protocol used to connect VoIP calls with multimedia sessions. SIP trunking is the enabler of VoIP.
SIP trunking can transfer data packets through Integrated Services Digital Network (ISDN), the internet and Virtual Private Network (VPN). VoIP calls on the other hand are facilitated over a private internal network or via the internet. Whereas VoIP systems and phones require computer connections to operate, SIP hardware are versatile.
VoIP software requires computers to run and can operate on the most basic operating systems. Free VoIP calls can also be made on dedicated voip apps for iphones. The fact that VoIP primarily operates on IP networks makes it open and susceptible to manipulation. SIP trunking protocols initiate and terminate communications in VoIP administration and technically enable all VoIP deployments.
The terms VoIP and SIP have been used many times to mean one and the same thing even though they aren’t technically the same. Their differences are made apparent by their functionalities. Without SIP protocols, there would be no functioning internet-based VoIP communications. VoIP refers broadly to phone systems that are internet-based.
Here are the benefits of implementing SIP trunking:
Traditional phone lines rely on physical hardware that are susceptible to interruptions and the vagaries of weather and depreciation. The technology behind SIP trunking is very reliable and many SIP trunking reviews can attest to that. Most SIP trunking providers provide mobile failover services in the event of interruptions.
This functionality allows users to stay connected when there are system challenges for example call drops by routing calls to other staff in an organization.
2. Ease of Deployment
SIP trunking providers offer a service that is very easy to use and deploy. This does not require the intervention of customer service teams that more often than not are poor at maintaining acceptable service level agreements. Actions like requiring on-site management may be executed with ease without the need of experts.
3. Consolidation of Network
The challenges that come with traditional telephones in the management of voice and phone data is made apparent when it comes to the payment of the two. SIP trunking harnesses fibre connections to consolidate voice and data into one network. This means that the two do not have to be paid for separately.
4. Cost Savings
It goes without saying that SIP trunking introduces flexibility to organizations in the way they manage their cost of calls. Many SIP trunking reviews contain competitive prices by various SIP trunking providers who offer top-notch communication services. This comes as an advantage to companies and especially startups.
Companies that transact their businesses overseas and have their business footprint globally may find conventional teleco rates very high and may eat up into their operational costs. Such costs may be significantly lowered by making the switch to SIP trunking providers who offer unified communication services at very flexible rates.
5. Centralized Communications
The challenges that businesses that operate in multiple locations is in the investment of telephone hardware to ensure connectivity. SIP trunking cuts all this by combining all the business units into one. Additionally, SIP trunking breaks the barriers imposed by traditional carriers and improves cross-border network interconnectivities.
Traditional phone lines require a huge outlay of investment when it comes to expanding communication infrastructure when business grows with time. SIP does not require a huge capital outlay whenever businesses expand and their capacities increase. Communications can be scaled appropriately according to business growth.
One of the greatest advantages of having SIP is mobility. When internet connections are affected, as they may be sometimes, SIP may enable communications to go on uninterrupted. Employees may remain connected through robust VoIP apps installed in their mobile phones. This can be done through one business phone line.
8. Virtual Phone Line
When an organization expands its base of operations, there may be need to add physical infrastructure and this includes phone lines. Conventional phone lines may be very costly to install when additional phones are required. SIP on the other hand doesn’t require additional handsets. Integration of phone lines only requires a data connection.
This potentially means that employees who work in far-flung areas can be connected and reached through one office phone.
9. Return on Investment
SIP trunking almost comes with immediate returns when compared to traditional phone lines. It does not require a heavy capital outlay to deploy and the systems aren’t costly. The investments costs associated with SIP trunking may have to do with an internet connection and a private branch exchange box that is SIP-compatible.
Installing a SIP system simply means that companies and businesses may immediately start to establish their savings goal and cut unnecessary expenses that are usually associated with telephone calls. The technology reduces the many incidences of relying on customer support that may lead to delays which may affect business operations.
10. Unified Communications as a Service
SIP trunking providers usually offer a bouquet of unified communication services that include instant messaging, instant messaging services, video and audio conferencing. These business tools are essential to boost productivity and improve bottom lines. Their flexibility and ease of use are valuable assets essential for productivity.
