Here's what I'm trying to do:
- I do a first call to Tinyphone (call 1)
- I answer call 1
- I do a second call to Tinyphone (call 2)
- I answer call 2
- I pass to the conference function the call_id of call 2 (conference work)
- hangup call 2 (call end)
I want call 2 to stay on a call with call 1 and the softphone to be off the call.
