Voice and data services are paramount for any modern business, so the choice between SIP trunking and Integrated Services Direct Network (ISDN) is a pivotal one.
An SIP trunk connects premises to the Public Telephone Network via IP/broadband and has turned into one of the top mediums in which to deliver VoIP services.
On the other hand, an is a circuit-switched telephone network system for the digital transmission of voice, video, data and other network services.
SIP trunking offers magnificent benefits to companies and here are some of the main advantages:
1. Improved support for business continuity
SIP trunking provides more flexibility than ISDN, offering protection against a number of possibilities that can impact how resilient voice and data connections are.
Issues such as damage to lines, office moves, or an inability to redirect calls can have a devastating impact on businesses. SIP trunking can reduce these problems and ensure companies can continue working through mitigating issues.
2. It saves you money
Compared to ISDN, SIP trunking can reduce line rental costs and help save a large amount of money for businesses by taking away all of their needless ISDN lines.
Doing this can help to save 50 per cent on line rentals and 25 per cent on calls. What’s more, using SIP trunking, companies will not need to spend money on changing stationery, adverts or listings.
Massive savings are earned when it comes to calls, too. All connections, even between international sites, are free of charge.
3. SIP trunking is now established as efficient and reliable technology
Now that SIP trunking has been in the market for a number of years, it has established itself as dependable technology and answered many of its critics.
The most recent research from Ofcom shows that 35 per cent of companies believe SIP trunking is the most important telephony system. It is especially popular for large businesses with complex requirements.
While many employers remain content with their ISDN services, it is clear that some businesses are reluctant to make the change. However, with SIP now consolidated as a strong alternative, those fears should soon dissipate.
4. Switching is straightforward and capacity can be altered
The transition between ISDN and SIP is a relatively smooth one. Firstly, no new lines are needed as SIP uses an existing broadband connection or runs over a dedicated voice circuit with the necessary service level agreements.
Moving to SIP will also mean removing existing ISDN lines and creating spare bandwidth, while existing PBX systems can be modified to utilise SIP trunks.
What’s more, SIP trunking is ideal for companies that experience seasonal spikes in activity as capacity can be added or removed when necessary.
5. Your business will be more prepared for the future
The cost savings and efficiency benefits provided by SIP trunking means the technology has grown into a leading option for the future.
Modern companies want agile data and phone services and, with communication over international borders becoming more important, the reduction in expenses from SIP means employers do not have to fall behind.
