Hi,
The reason I am trying to use bridge_pre_execute_bleg_app is when I call from Leg A to Leg B, Leg B answers but there is a silence before ringtone.
I tried ignore early media, everything, but nothing works.
What I need to do is to bridge the call only when Leg B starts ringtone, I have to ignore the silence when Leg B already answer, It is a channel with many problems, that is why we want that Leg A doesn’t hear the silence.

Do you have a full pcap w/ both SIP and RTP for both legs to go along with the full freeswitch log for the call? The reason I ask is that I'm not sure you've actually defined the conditions of failure. If the A leg is "hearing silence" then you need to make sure you know where that silence is coming from. You also mention that the B leg is a channel with many problems. Could one of those problems be that it is sending back a 200 OK (i.e. call was answered) but the media stream contains silence then ringing?

I think if you take a closer look at what is actually happening it may help you figure out what the solution will be.
