Question 1

How do I make a call with FreeSWITCH?

Accepted Answer

To make a call with FreeSWITCH, you’ll typically need to configure SIP profiles for your endpoints (such as softphones or VoIP devices), define dial plans to route calls, and set up SIP trunks for external communication. Once everything is in place, you can initiate calls by dialing the configured extension or external number.

How do I set up a SIP trunk to make external calls with FreeSWITCH?

To set up a SIP trunk, create a SIP profile for external communication, configure the trunk provider’s SIP details (e.g., SIP server, username, password, etc.), and define dial plan rules that specify how outbound calls should be routed through the trunk. Once configured, FreeSWITCH will handle call routing to external destinations.
