Well, I've almost done that. I can detect the ringback, fastbusy and voicemail tones, I can also detect when the B-leg starts talking. I am using tone_detect and VAD (in sip profile) to get these events and act accordingly. On Sat, 2010-03-27 at 00:07 -0400, Mathieu Rene wrote:
And how exactly are you planning on detecting answer on the B-leg?

Because the B leg is always immediately answered, it is giving false answer. The ringback, busy and fastbusy tones are being played once it is answered. And if I use the bridge app.. once the B leg gets answered it answers the A leg.

no,
That sounds a little over-thought though? Why can't you just use the bridge app? We have extensive parameters to do progress supervision on the wiki.

I already have the incoming A leg in the switch and I want it to stay in early media and "bridge" it one-way only to a originated B leg that is always answered since the very first second.
What I am trying to do is some kind of call progress supervision on the B leg and answer and bridge to the A leg only when I detect the B leg was really answered. Before that I just want to pass the audio coming from the answered B leg to the early-media-state A leg.. so the A leg can hear the ringback tones, voice-mail messages, etc.
I already detect the tones and when the B leg is really answered, at that moment I can do an uuid_bridge of both uuids and get the legs bridged. But I don't see how I could pass audio from B to A before answering the A leg.
Is this possible in any way with FS??
Maybe I didn't understand you, but I don't see how could it be possible to do it with an inline dialplan.
Thnks!!

yes,
don't park it, have it dial the other leg with the bridge app.
originate <dialstring1> bridge:<dialstring2> inline

Does anybody know if there is a way to "bridge" an answered channel to a channel that is in "early media" state?
The scenario is like this:
Channel A Channel B -------------------> FS -------------> (pre_answer, park) (answer) <---<---<---<---<--- Audio <---<---<---
When the channel A arrives I pre_answer and park it, so it is in "early media" state. After that I originate the channel B. When the channel B answers I just want to relay the audio coming from B to A, I don't care if A can't talk to B at that moment.
Is there a way to achieve this? Some ideas?
Thnks!
