One key advantage of fixed VoIP numbers is that, unlike non-fixed VoIP numbers, they send the exact location of a 911 dialer to public safety answering points (PSAPs)—allowing the call to be traced in an emergency.
Enforce a strong password policy, requiring all users to employ unique, strong passwords at all times, and store them only within an acceptably robust password manager specified by the IT security team. It used to be recommended that passwords were regularly changed, but this often led to compromises in other areas — so it’s more important that passwords are complex and long, and never reused.
Make sure that remote or off-site users in particular are connecting securely, using VPNs, and encrypting their connections appropriately.
Manage access intelligently. Within the Ringover dashboard it is the work of a moment to activate new inbound and outbound numbers, for example to permit local presence in a new campaign. But you should review usage and deactivate services no longer required on a regular basis, to save on subscriptions as well as increasing security.
Manage usage by need: further to the above, consider each user account individually, and enable exactly what is needed and nothing more. If someone has no need to call a particular country, for example, lock it down — you can easily add services if that user’s needs change, and in the meanwhile they cannot be tricked into calling a scammer’s number there.
Monitor actively. Review your call logs and set alerts to ensure your usage remains within expected parameters. Sales people need to make a load of outbound calls, an administrator maybe fewer… So, something is amiss, if they are suddenly hitting up a series of premium rate mobile lines on the other side of the world.
However well you manage things internally though, the single best thing you can do to protect your VoIP phone system and other cybersecurity protection is to outsource as much as possible — to a respected and established international provider like Ringover.
