> ASTERISK-29989 fixed an issue a while back where busy channels were unavailable when they weren't.
> Well, we now have the reverse issue: unavailable channels are busy when they're not.
> (e.g. mixup of BUSY and CHANUNAVAIL)
> Ultimately, the underlying issue here seems to be that the current mechanism of determining whether a DAHDI channel is insufficient. If the peer is available but in use, it should be busy, and if it's not available at all then it should be CHANUNAVAIL.
> This is actually not a regression, the problem is in chan_dahdi and not app_dial.
> I don't have a solution just yet but you can assign this to me.
