SECURITY FOR SIP ACCOUNTS AND CALLS
Protocols and Ports
By default, after a factory reset, all the accounts are not active. And it is recommended to disable the unused
ports. Under Web GUI → Accounts → Account X → General Settings → Account Active: “No”
➢ Users can also disable Direct IP calls on all ports under Settings → Call Features: Set “Disable
Direct IP Call:” to “Yes”
• SIP transport protocol:
The WP810 supports SIP transport protocol “UDP” “TCP” and “TLS”. By default, it’s set to “UDP”. It’s
recommended to use “TLS” so the SIP signaling is encrypted. SIP transport protocol can be configured
per Account under web UI → Accounts → Account X → SIP Settings → Basic Settings. When “TLS”
is used, we recommend using “sips” instead of “sip” for SIP URI scheme to ensure the entire SIP
transaction is secured instead of “best-effort”.
