# IP Allowlist

You can enter IP addresses (friendly host) here in a static allowed list for allowing access to IP services (e.g. SIP) without application of the Denial of Service (DoS) restrictions.

## Automatic addition to allowlist

Mitel servers (e.g. MBG, SIP DECT OMM) are automatically added to the allowed list in the background (not visible here) to prevent a potential block of these IP addresses/servers if DOS restrictions are violated.
