get status of SIP invite of Freeswitch

I am new to Freeswitch. I have successfully connected two FSs. First FS redirects to second FS. Now I would like to get the information about the SIP invite; whether it is received at 2nd FS or not programmatically, when call is made to 1st FS. I am open to scripting option as well apart from configuring the xml files.

Solution

  • You can write script which will listen for channel states on ESL interface of second Freeswitch, when call will hit extension of it you should get CHANNEL_CREATE event:
