CamelotKniggit,
It appears you have done everything correctly. I had a user report that while the DSLReports article for keeping callerID and remote DVR did work back in 2018, they have since had issues with functionality.
Apologies, I personally don't use those two features, so I haven't checked on if this setup still works. I'll run some tests on my network over the next couple days to see if I can get it working and report back.
Thanks!
