Spoofing is the use of false numbers that can fool people into believing that the call is from a trusted source. Callers commonly claim that they are government or financial institutions so that victims are more willing to divulge personal details.

SIP Trunk Security Best Practices

Deny by Default

VoIP and SIP numbers are so common that it can, sadly, cause security issues. It’s a good practice to deny everyone except for authorized users that you know.

Strong Passwords

It’s an regrettable truth that most people have poor password security. Therefore, it is a good idea to ensure that everyone with access to your SIP Trunking Solution have a strong, unique password with numbers, letters, capitals, and unique symbols. You should also make it regular practice to change your password on a routine basis.

Disable Unused Services

You should also disable any services that you’re not using. The reason to do this is because no one in your organization is keeping an eye on it. This means it is a vulnerable spot for attackers.
