[Freeswitch-users] How to dial an extension in Freeswitch after the call in connected?

Hi there, I have a question regarding having FreeSwitch dials an extension number after the call is connected. Here is the condition: Freeswitch would get a call information from database and make an outbound call. Once it is connected, and if there is an extension that we want to reach at that number, we would wait 5 second and dial that extension number. Right now I am using C# code and I don't see any API would allow me to dial an extension. Could someone please help me? Thanks, Frankie
