Thanks for your bugreport.

It is true that Debian-distributed Asterisk includes patches which may
indeed affect the above.  But only possibly, not certainly.

If it is possible for you to try test your setup with
upstream-distributed Asterisk, then it would help ensure that truly what
you experience is a bug introduced by a Debian patch.
