VoIP or ISDN?

March 14, 2016

Posted by: Emma Bailey

More and more business are switching from a traditional ISDN phone system to a VoIP (Voice over IP) system. Here’s why …

It’s Cheaper 

Whichever way you look at it a VoIP phone system is cheaper than an ISDN system. Internal call charges between multiple offices are FREE with a VoIP system, unlike an ISDN phone system where your phone provider will charge for each internal call made.

Reduced Downtime 

If your VoIP system has a fault it can take up to 10 hours for some providers to repair it. If your ISDN system has a fault it can take up to 72 hours to repair.

Greater Adaptability

VoIP phone systems are designed to adapt to your business needs. Whether it’s needing to add a new office, allow some staff to work from home, some clever call routing, non-geographic numbers, additional local numbers, call forwarding to mobiles and many other options. A VoIP system can add these features easily. Unlike ISDN that limits business to less than 10 local numbers, with VoIP you can add as many numbers as you wish.

Easy Scalability

As the system is hosted on high availability servers you can easily add new phone system users on a permanent or temporary basis. So as your business grows your phone system grows too.

Disaster Recovery 

In the event of your office or offices being affected by a disaster such as a fire or a flood, the phones can be instantly re-routed elsewhere. For example to another office or to staff mobiles. This allows you to continue to run your business effectively.

In Conclusion

VoIP is by far the way to go when it comes to upgrading your telephone systems, however it is dependent on your broadband connection. You do need a resilient and reliable broadband connection to take advantage of all VoIP has to offer.
