Cisco IP 8945 - SIP Multicast MOH issue

[Maxime Peccoux]

Hello,

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:

• If my phone is running SCCP firmware, I can hear the music
• if my phone is running SIP firmware, I haven't the music

My network config is ok. Indeed, in sccp, everything is working fine.

Have you an idea ?

Best regards

Our environment is:

CUCM 9.1.2.10000-28

Cisco IP Phone 8945 Firmware 9-3-4-17 (SCCP / SIP)

Seems to be a bug, use older SIP firmware (9-3-2-12)and Multicast is working...

but other things may not...

Hello Peter,

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.
