[asterisk-users] Early media using ARI

[Jöran Vinzens]

Hi, thanks for the hint.

What we have done so far:

- get an incopming call
- create a new channel
- set stuff on outgoing channel
- dial outgoing channel
- get a Dial Evente State "PROGRESS"
- push both channels into the bridge

then nothing happens by default.

we will try your suggested way! (putting both Channels into bridge before
dialing the B channel)

BR
Jöran
