Here are some of the key ways you can keep your system safe.

1 Use security software

Having security software on your endpoints – and making sure it’s kept up to date – is the first line of defence for any system, and VoIP is no exception. Don’t neglect mobile devices like smartphones and tablets which are frequently used for VoIP calls.

2 Strong passwords

Setting a strong password is an effective way to protect your VoIP system. Ideally, this should be 12 or more characters long and use a combination of letters, numbers and symbols. Don’t reuse passwords on other systems as if one is compromised that puts the others at risk. If you have trouble remembering passwords then install a password manager.

3 Backup often

If you should suffer a data breach or a hardware failure or some other reason prevents you from accessing your account, it’s important that you have a copy of your data stored elsewhere. Save it to a cloud service, but to be doubly safe you might want to take a copy to an external drive too – store this off-site for safely.

4 Check your history

If you adopt VoIP wholesale suppliers like idtexpress.com, always give the ability to log the call history of your system. You shouldn’t just file these logs away though. Checking them regularly can give you advanced warning of any suspicious activity, such as a sudden increase in calls from a particular login, or more calls to overseas numbers. You can apply restrictions to the system to prevent abuse – restricting overseas number for example.

5 Use a firewall

Any system that is connected to the internet needs to have a firewall. For VoIP use though you need to ensure that it can cope with the type of traffic involved. You should be able to configure it only to allow access for defined IP addresses so that you can prevent unauthorised use of your account.
