Configuring BLF on a SPA525G connected to CUCM

Hi there,

I have a SPA525G connected to our CUCM and registered fine as a SIP device, I can assign speed dials to the spare line keys fine but configuring BLF is proving to be a challenge!

Basically under the phone tab of the SPA525G's web interface I have picked a spare line, disabled the extension, set the share call appearance to private and entered the following syntax into the extended function field:

fnc=blf+sd+cp;sub=215@192.168.104.2;ext=215@192.168.104.2

When this is applied the line key button is a solid orange colour, the speed dial function works fine but not the BLF feature. I believe the solid orange light denotes that the phone has failed to subscribe?

Any pointers would be much appreciated.

Thanks,

Keith

Hello Keith,

How did you manage to get the phone to register in the first place?
