MultiCast MoH Bugs

During my testing I faced the following bugs and would like to share them.


Multicast MOH reversing G729 codec to G711 codecs - media resource issue

Symptom: Multicast MOH is using G729 codec instead of G711 codec even though the region mapping between the 2 regions is set to 64kbps
