Description:I have tested two different SIP trunk providers and when putting an outside caller on hold from my Snom 360 the outside caller cannot hear any Music On Hold.
Downgrading to Asterisk 1.4.24 fixes the problem.

Possibly, I'll test the patch from ASTERISK-15159 and confirm

By: David Brillert (aragon) 2009-11-23 13:02:31.000-0600

Yes, confirmed.
I just checked out SVN-branch-1.4-r230875 and MOH works fine
