[Freeswitch-users] How to send SIP signaling message from fs console.

Hi, I am wondering how to send sip signaling message from the fs console for the particular user/caller. I found respond dialplan application to send sip message back to the caller. Like <action application="respond" data="480 Try again later"/> ​Is there any way to send sip message back to the caller. One use case is call rejection or playing with SIP​ -- Thanks & Regards, Naveen Tamanam
