We have Polycom IP560 phones with BLFs configured and we are seeing the BLF intermittently lose their blf subscription. SNGREP shows the phones subscribing to BLFs every 1.5 minutes. (We have Yealink phones on our network and never see them subscribe to BLFs)
Polycoms will subscribe to BLFs every 1.5 minutes. Sometimes they receive a 202 Accepted. Other times they receive a 407 Unauthorized. I can't figure out why Fusion is responding with a 407.
Also why is Polycom BLFs subscribing every 1.5 minutes when I don't see Yealink BLF ever subscribing?
