Termination Gateways

Termination Gateways are used to call out from phone.systems™ using created SIP accounts or to forward calls to PSTN destinations. A third-party termination provider must be added and configured under the Gateways tab section.

To access and manage your termination gateways, click Trunks in the sidebar menu and select the Termination Gateways tab.

Step 3. Configure CLI Rules (Optional):

The CLI Rules are used to automatically modify the source and destination numbers sent to the termination gateway, allowing users to add and remove prefixes or rewrite numbers per gateway.

• SRC Rewrite Rule/Result (optional): Modifies the source number that phone.systems™ sends to the provider’s termination gateway.

• DST Rewrite Rule/Result (optional): Modifies the calling destination number that is sent to the provider’s gateway.
