VoIP Security

Smartvox solutions have a strong focus on Security and prevention of Dial-Through Fraud.

Solutions available using OpenSIPS include:

  • SIP Proxy: Screening out malicious SIP requests & hiding vulnerable infrastructure
  • Transparent Registrar: Source address ACL’s; domain re-direction; Intrusion detection
  • Carrier Proxy: Source address screening, concurrent call limiting; destination fraud detection

We can supply and support some dedicated hardware SIP Firewalls from Pika and Allo Telecom.

Smartvox can also assist with installation and configuration of fail2ban, an open source project that provides advanced dynamic management of iptables firewall rules. Suspicious source addresses are blocked in response to automated analysis of application log files.

We are happy to advise on ways to harden your Asterisk-based IP-PBX systems and provide a massive range of free information through our Wiki.
