Tips

To maximize security, configure the SBC's SIP firewall and enable TLS/SRTP for all external SIP trunks. Use the two WAN/DMZ ports to separate voice traffic from data and create a DMZ for SIP trunking. Regularly update firmware to ensure compatibility with the latest UC platform versions and security patches.
