The "Gateways" section is used to connect external lines. This is necessary for receiving and making calls outside the system, as well as for the operation of such a function as "Mobility".

SIP gateways have different types of registration: Outbound, Inbound and without authentication - DID.

DID (Direct Inward Dialing) – without authentication. Registration session for this type of registration is not available. Validation of an incoming/outgoing call session occurs via an IP address, usually external and static. It is used for trusted addresses, for example, for communication between two offices of the same company.


Go to the "DID" section and click "New Gateway" to create a new DID gateway
