Hi, I am now on v15.5 and every minute or so I receive a “Trying to establish CSTA session to <sip:xxx...” message in the Activity Log, because not all phones support the uaCSTA feature. I use a mix of W52P, W56P, T48G, N300A and Linksys ATA’s. For monitoring function the logging level is set to Medium and I don’t want to set it to Low. Is there a way to suppress this messages from the devices that do not support the uaCSTA feature? Thanks for the help.
