How do you help prevent fraud and unauthorized use?

Yes, here are some measures we use to protect your accounts:

1. We block international calls on all accounts by default. You can enable specific countries on your account by contacting Support.
2. The SIP authentication credentials for your account are 10-digit random numbers for high level of security.
3. We have intelligent firewalls on our servers which blocks IP addresses based on multiple failed registration attempts.
4. We optionally support and recommend IP authentication as opposed to the default registration based authentication. IP authentication protects your account by allowing calls only from your static IP address.
5. Our website has SSL support which ensures that your authentication and credit card details are sent over secure encrypted channels over the Internet when you use our website.
