SIP vs ISDN, one clear winner………….
With far more reliable and powerful broadband solutions now available, for businesses, it means that the use of SIP Trunks as a viable alternative to traditional lines is now a cost effective and reliable option. With over 1 million ISDN channels having ‘disappeared’ since 2008, SIP has been a major benefactor.
SIP is a main line product and has been for the past few years. Companies would only change from ISDN to SIP when there is a compelling driver or trigger such as, moving, changing telephony application, upgrading replacing a data circuit, disaster recovery applications etc.
That has changed as more and more UK businesses outgrow their telecommunications solutions, they begin to look for an alternative that offers more flexibility, reliability and value for money. With decreasing cost’s a business can change over to SIP at any point in their business journey. The set up can be half the cost and on-going operational costs are significantly lower too.
There are two key points to be addressed when moving to SIP, the first is connectivity. The connectivity needs to meet the requirements and expectations of a business and disaster recovery should be a key component in any data installation.
Secondly, ensure that your broadband is up to the job. SIP trunking is only part of the equation. If your ISP is unreliable, your broadband connection is not optimised for VoIP (too much latency or jitter), or you use the same connection for voice and data, you are likely to run into problems.
The flexibility SIP offers companies large and small over ISDN has saved thousands of pounds as companies are not restricted to a locally hardwired based exchange. With SIP the exchange moves into the cloud. Wherever a data circuit is connected calls can be made and received, voice is an additional application delivered over a data connection so no need to pay for an ISDN circuit and a data circuit.
The IT department used to be the ‘chap with an interest in computers’, now if your computer is down, you switch to your mobile to send and receive emails.
If your internet goes down, you go home or to the local coffee shop and log on. As voice is now rapidly moving from ISDN to a data pipe the flexibility of how we use voice as an application will continue to evolve.
To sum up, with SIP you are not constrained to one pipe from one exchange, business continuity is far easier to design and use within the world of SIP along with cheaper set up and running costs.
