Unable to establish VIDEO with a Cisco 9971 using Cisco MCU 5310
There is an issue establishing video conferencing between a cisco 9971 phone and a cisco MCU 5310.
When calling from a 9971 phone towards a MCU we are not able to establish video, only audio connection. We have tested a point-to-point connection between two 9971 phones and video works fine. We have also tested several Jabber clients in a conference using the MCU which also works fine. Finally a point-to-point call between a 9971 phone and a Jabber client works fine. We have tried different settings on the MCU but have not been able to find a solution.
The cisco 9971 phone was updated to firmware 9-3-4-24.
