Re: ¿Can CUCM be used to force Softphones to zero the DSCP fiel
I currently am doing CBMarking on my edge routers to "detect" and zero these packets´ DSCP, but it does not scale well since VLANs are created/deleted quite frequently (actually, the LAN admin does not always tell me as soon as he executes a change).
The reason why we want this is basically Call Admission Control. People travel a lot between offices and start their IP Communicators on locations that could belong to other CUCM cluster. When this happens, the user´s CUCM does not know whether a user is (or is not) in its real site, so CAC is not applied properly.
I read a bit about Device Mobility, but as far as I understood, it works WITHIN a cluster. In my case, the company has three CUCM clusters, and mobile users might want to start IP Communicator across any of these clusters.
Thank you very much again for any hints you may give me.
