Session Initiation Protocol, or SIP, is a telephony service based on Internet Protocol (IP). It’s a virtual system, with SIP trunk lines being equivalent to physical T1 phone lines from a traditional company, going out simultaneously over a public network.
SIP trunking can be deployed over an on-site IP-PBX (Internet Protocol – Public Branch Exchange) using software, and has considerable advantages over a standard phone system.
Today, we’ll look at some of the benefits that SIP Trunking can bring to a business.
#1: Cost Savings and Greater Economy
With services available on an as-needed basis, there’s significant savings on the monthly fees associated with traditional service providers. Physical lines don’t need to be bought in and added to scale up a service, and there’s a single plan covering all communications – rather than separate packages for voice and data.
Voice over Internet Protocol (VoIP) ensures that local call rates apply even for international communications. This is because it’s not necessary to tie your phone number into one specific geographical area, using VoIP, you can choose a number that is from anywhere in the world and use it while on the go, on any device. And you can make the most of your internet connection by adding voice traffic to your existing data service, within the same bandwidth allowance.
#2: Rapid Returns on Investment
There’s no huge capital outlay for cabling and hardware. SIP trunked services can be bought as you need them. However, there are further cost benefits such as:
- Lowered risk of downtime saves costs on both unplanned downtime and staff productivity.
- Lack of ongoing maintenance costs (depending on specific set-up)
- Free and low-cost local and international calls enable further savings
- Enabling of collaboration features and with them, increased productivity through conference and video calling
- Consolidation of existing systems and additional of further complementary services and features such as hosted PBX and unified communications.
In most cases, you can expect to see a return on your investment within six months, or less.
#3: Scale and Flexibility
Unlike traditional phone lines (which have to be bought in and added physically, typically in sets of 23), SIP trunks are virtual. Once the software is in place, new lines can be added (or removed) whenever they become necessary. So there’s no need to pay for channels that you’re not actually using – as is often the case with physical lines.
#4: Reliability of Service
Localized events like power failures, circuit damage and extreme weather events that would paralyze traditional phone networks don’t have the same effect on SIP Trunking. Via a provider’s system of redundant stations, calls can be re-routed automatically to mobile phones and your sites in other parts of the world, using protocols based on your specific business rules.
No more missed calls.
#5: Bringing Voice and Data Together
Using SIP Trunking and its underlying Internet Protocol, voice, data, multimedia, Instant Messaging (IM) and applications can be brought together as a unified communications (UC) solution, with a user interface that both IT personnel and your people in other departments can comfortably work with.
And SIP Trunking can form part of a hybrid set-up, combining traditional telephone equipment and VoIP-based systems, as your organization makes the transition between technologies.
SIP Trunking and IP telephony have a lot to offer any business. Revenue savings are significant and when coupled with business continuity (thanks to reduced risk of expensive downtime), increase even further.
