Limitations

ENP Ignore / reject / trust / authenticate

The ENP has a number of tables that may be configured to define how to initially handle incoming messages:


  • IPs to ignore (up to 100 entries):

• Explicit blacklist of specific IP addresses and IP address ranges.

• Any SIP message from any of these addresses will be dropped and not responded to. This can help deter devices from retrying requests or attempting Denial of Service attacks.


  • IPs to reject (up to 100 entries):

• Explicit blacklist of specific IP addresses and IP address ranges.

• Any SIP message from any of these addresses will be actively rejected with a 403 – Forbidden


  • IPs to trust (up to 100 entries):

• Explicit whitelist of specific IP addresses and IP address ranges.

• If ITSP Registrar / Proxy is in-accessible this list specifies whether endpoint devices should be treated as trustworthy devices for registering and making calls.


  • SIP Auth table (up to 120 entries):

• If the ITSP Registrar / Proxy is in-accessible and a SIP message comes from a device that is not in the ‘IPs to trust’ list, the Vega will ask for authentication before handling the message

• The SIP Auth table contains:

- Authentication User name

- Authentication password

- Authentication realm (to be same as Registrar / Proxy domain)

• Failure to authenticate will result in a response 407 – Proxy Authentication Required
