VoIP Security: Best Practices for Businesses
VoIP security is crucial for protecting your business
communications. Here are the best practices every business should
follow:
Use Strong Encryption
Ensure all voice traffic is encrypted using SRTP (Secure Real-time
Transport Protocol) and TLS for signaling. This prevents
eavesdropping on your calls.
Implement Strong Authentication
Use complex passwords for all SIP accounts and enable two-factor
authentication where possible. Regularly rotate credentials.
Network Segmentation
Place your VoIP traffic on a separate VLAN from your regular data
traffic. This improves both security and call quality.
Regular Updates
Keep all VoIP equipment and software up to date with the latest
security patches.
Monitor for Anomalies
Set up alerts for unusual call patterns such as high volumes of
international calls or calls at unusual hours — these could indicate
toll fraud.
Choose a Secure Provider
Partner with a VoIP provider like OurSRV that takes security
seriously and offers built-in protection against common threats.
