Our client has a mixed environment of Cisco 8861-39CC phones and some polycom devices, as well. They use Unified Office to manage their phones.
Recently, we were tasked with configuring their Cisco phones with BLF - and, we've hit a bit of a snag. There is nothing listed in the SIP URI field. Not sure if that's the problem (assuming it is, but I know less than Jon Snow about Cisco phones), but here's what we have:
Test Phone:
Extension = 500
UserID = 500001
Proxy = unified.office.server:port
Voice > Phone > Line Key 2:
Extension: Disabled
Short Name: $USER
Share Call Appearance: Private
Extended Function = fnc=blf+spd+cp;sub=500001@unified.office.server;ext=469@unified.office.server;nme=Steve 1
Voice > Phone > Line Key 3:
Extension: Disabled
Short Name: $USER
Share Call Appearance: Private
Extended Function = fnc=blf+spd+cp;sub=500001@$PROXY;ext=468@$PROXY;nme=Steve 2
The result:
The lights on the buttons next to 'Steve 1' and 'Steve 2' just blink all day.
So, rather than waste any more time - I figured I'd check to see if it's even possible without having something in the SIP URI field. Thanks in advance for any help.

You beautiful, beautiful genius, you!!
I am 5% ashamed of how I didn't even try that on a whim. And 95% relieved beyond understanding.

It would be really nice if Cisco could correct their documentation to reflect your answer. Currently the documentation is WRONG. I wasted 2 days troubleshooting this until I saw your accepted post, so thank you for that.
I tested your answer and simplified the template to display BLF on the CP-88xx series like so:
<Extended_Function_n_>fnc=blf;sub=watched-phone@server;nme=Name to appear on display</Extended_Function_n_>
The "ext=" term is not even needed, despite what the documentation claims.
Otherwise, the 8800 series are really nice phones.

Try this as well:
fnc=blf+sd+cp;sub=466001@$PROXY;ext=466001@$PROXY;nme=John D.
