ISDN30 Alternatives

For the vast majority of businesses in the UK, there are only two real alternatives to consider when switching from ISDN30, they are:

Cloud Hosted VoIP
SIP

We will now explain both of them and give examples of scenarios when we would recommend you use each.

SIP (Session Initiation Protocol)

If you’d like to keep your existing PBX, SIP trunking may be the best solution for you.

To put it simply, SIP integrates your current PBX with VoIP, which means you can continue using your current phone system.

Whether this will be the most cost-effective solution for you may be another story. On one hand, your team won’t have to learn to use another phone system. But on the other hand, you’ll have to maintain your own PBX, which may cost more over the long term.

If you’d like to save your team’s time in the long run, a cloud hosted VoIP solution may be a better option.

Cloud Hosted VoIP

Cloud hosted VoIP is a done for you solution that gives you all the benefits of a privately managed PBX, without you having to manage it yourself.

You also get more flexibility, and it often costs less too.

The quality of service you’ll receive with cloud hosted VoIP will depend on the provider you go with, but as an example – if you were to use ours, you can expect:

Better call quality than your current ISDN30 line
Call recordings for training & monitoring purposes
The ability to make and receive calls from anywhere in the world with an internet connection
Smart queuing & call routing
Skype for Business and CRM integration options
The ability to keep your existing phone numbers
and more
