I am having an issue where our 9620 phones are not logging missed external calls. They will log missed internal, but not external. Avaya (I believe as a last straw since it has been 5 weeks and they do not have a solution) is recommending upgrading the firmware. I want to do this on a single station to test. How can I do that? This is a CM 6.0 S8800 with IP stations. I am used to the old DCP station firmware download. All the documentation points to pushing the new files onto the HTTP server directory, but I'm concerned this will make it available to all my sets. We also have a strict change request policy, so I cant just swap the files out, quickly boot the test set, then swap them back.
