[OpenSIPS-Users] cannot bridge_retry when bridge established with prov_media_uri

[João Coucelo]

Hi all,
I'm validating the different supported b2b_bridge scenarios. I noticed something that I was not expecting in the b2b_bridge_retry scenario; i could not do a bridge_retry when the b2b_bridge is established with prov_media_uri. The bridge retry is done for entity 1, and in this case that is the media entity; however the retry should be done for the "callee" entity, and not for the media.
I've added to my b2b_logic_reply logic to run b2b_client_new() and b2b_bridge_retry() upon a 4xx error response.
This works when the b2b_bridge is established with two entites, e.g. b2b_bridge("caller", "callee");

However, if I add the media_url to the b2b_bridge, the b2b_logic_reply route is not able to associate the incoming 4xx error response to the callee entity.

If I remove the if condition that checks that the error was received for the “callee” entity and do the b2b_bridge_retry anyway, I get ERROR:b2b_logic:b2b_script_bridge_retry: The 'b2b_bridge_retry' function can only be used fornegative replies from the second entity
