I have an issue with my IP Phone SIP 8945 (SIP8941_8945.9-3-4-17).
So when I enabled Multicast (option on each Media Resource Group) for Music On Hold:
My network config is ok. Indeed, in sccp, everything is working fine.
Have you an idea ?
Our environment is:
Cisco IP Phone 8945 Firmware 9-3-4-17 (SCCP / SIP)
When I use a previous firmware, it's working but the music comes only after a couple of seconds ~7-8s. Have you ever seen this behavior
So it seems there is a bug in the firmware 9.3.4-17.
