How to correctly determine bridge result (answer/no answer and reason) after executing Bridge on already answered channel? endpoint_disposition shows 'ANSWER' as call is answered.

Call goes to FS, FS answers, reads digits and attempts bridge to some destination. But I can't reliable determine whether this call was answered or rejected with some status, as originate_disposition is set to SUCCESS even if we just get early media, and endpoint_disposition contains 'ANSWER' related to current channel.
