Recording stops when one channel leave the bridge (ARI)

Asterisk Asterisk APIs

Hello,

We are observing a weird behavior with asterisk, ARI and recordings.

It seems that is I start a record on a bridge that contains two channels, and a channel leave the bridge (I remove it via ARI), the record stops.

Anyone aware of this? why? can we prevent this from happening? (i will put a new channel on the bridge later, record should continue).

Some console output to try clarify :

Maybe add a dummy place holder channel that does nothing but keep the bridge from, hmm, collapsing ? Let it handle the MOH when needed ?
