SIP phones are amazing for business – they’re smart, efficient, and perfect for crystal-clear communication. But just like your favorite gadgets, they need a little TLC to stay secure. Hackers love unprotected SIP lines but guess what? You’re about to become a SIP security superstar!

Ready to shut things down and speak smart? Let's get into some need-to-know hacks to secure your calls.

SIP Phone Security is Important

Your SIP phone is your doorway to the world. But if it's not secured, it could be a backdoor for cyber intruders. That is, eavesdropping, call hijacking, or worse – huge data breaches. Not cool.

But don’t worry, we’ve got your back with the top security moves every SIP user should follow!

Top SIP Phone Security Tips – Like a Pro!

Change Default Passwords ASAP!

Seriously, First things first – ditch those factory-set passwords. Go for strong, unique passwords that include letters, numbers, and symbols.

Enable Encryption

Use SRTP for voice and TLS for signaling. It's like turning your SIP phone into a digital vault!

Limit Access by IP

Lock it down! Only connections from trusted IP addresses.

Use a Firewall

Your firewall is your front-line defense. Establish rules to shield SIP ports and reject unwanted traffic.

Keep Firmware Updated

Don't neglect those updates – they close security holes and keep hackers at bay.

Disable Unused Features

Not utilizing voicemail-to-email? Disable it. Less features = less risks.

Monitor Call Logs Regularly

Notice anything suspicious? Such as a burst of calls to one number? That's a warning sign!

Enable Two-Factor Authentication (2FA)

Double the login security = double the protection. If your SIP provider supports 2FA, enable it!
