Source notes citing this source

• A FreeSWITCH gateway is a named outbound SIP trunk defined in a Sofia profile's gateways block that tells the endpoint how to reach a remote provider or peer and can optionally register an account there. in context
• To send a call out a gateway, the dialplan bridge application uses the endpoint string sofia/gateway/<name>/<number>, where <name> must match the gateway's name attribute exactly. in context
• In the vanilla layout, gateway XML files go in conf/sip_profiles/external/ and are included into the external profile's gateways section by an X-PRE-PROCESS include. in context
• The gateway ping parameter makes FreeSWITCH send a SIP OPTIONS request to the gateway every N seconds as a keepalive. in context
