Why doesn't BLF work with PJSIP Extensions?

Hello,

I am having an issue with BLFs and a pjsip extension. I have extension 101 which is a pjsip extension and has 2 phones registered to it. I just set up BLFs using the commercial endpoint manager, but all the BLF fields show up in orange.

Can someone please help me figure out how to get this working?

Thanks
