I have trouble with Music on Hold on a 4.1.3 install. My customer uses a USB Device connected to CCM as audio source. I have enabled multicast on this audio source as well as on the server to enable local moh on SRST branch site. MRG used on HQ doesn't use multicast. It has worked for a while (a week or two) but it seems the service finally crashes with no mean to restart it but reboot the CCM.
Thanks for any help.
