We are going to implement VoIP and found that the bandwidth reserved for realtime traffic is completely used by OpenVPN packets between MSM access points and our MSM760 controller. These are marked with DSCP 56.
In the VSCs that utilize tunneling, we set "Priority Mechanism" to "Disabled" and disabled "Upstream Diffserv tagging". Still, nothing has changed. So, now our phones don't work because Guest Internet is transported in realtime class ...
What else can we do to change this setting?

Sorry, I read your reply only now.
I don't have an issue with the PORT that is used. My problem is that the packets are marked with IP DSCP 56 which is CS7 and is treated high-priority / realtime traffic in most devices - and which is exactly what I do NOT want for the free guest network.

what you can try is to create a VSC only for your phones, lets call it Wireless-VoIP, and use QoS priority setting "VSC-based very-high". This was, your voip phones will always be high-priority.
Also, management traffic between APs and controller should not take lots of bandwidth. You should put your other VSC QoS to a lower setting.
