Bypass media is a special mode, not all commands work with it. Pretty much any command that works with media does not work with it.

Does the same stands for Proxy Media mode ("inbound-proxy-media=true")?

You need to bring the media back to fs first

Please correct me if I am wrong: I should answer both legs first, than bridge them with "intercept" command and move FreeSwitch out of the media path with "uuid_media off uuid"?
However I thinks intercept is blocking command, how can I queue "uuid_media of" from LUA script to be executed right after the call is intercepted?

Hi,

I need to implement this scenario:
inbound SIP call A is waiting indefinitely for inbound call B and then they are bridged together. RTP media should flow directly from A to B and vice versa while FreeSwitch should control SIP signaling.

I made some progress but I could not make media bypass mode to work.

My SIP profile settings:
    <param name="inbound-late-negotiation" value="true" />
    <param name="inbound-bypass-media" value="true" />

Dialplan for leg A:
    
    <action application="park" />

LUA script for leg B:
    leg_a_uuid = ...
    session:execute("intercept", leg_a_uuid)

This works but FreeSwitch is still in RTP media path with following error in the log:
[ERR] switch_ivr.c:1718 Can't re-establsh media on sofia/myprofile/xyz
It worth mentioning that I do not answer or send early media before executing intercept command so there is no prior media on both channel A and B.

Any ideas what needs to be done to make this scenario work without RTP proxying?
