Re: BLF is not working

Your configuration fine. Kindly do these 2 steps & let me know..I aso have 6.1 & it's working fine.

Under Protocol Specific Configuration (on the Phone):

1. Presence Group*---> Select the bew Presence Group that you created.

2. Subscribe CSS--> Selcet the CSS on which IP phone is residing.

Re: BLF is not working

Yes I have updated the two parameter and reset and reboot the CCM also, but the BLF/SD shows like normal speed dial.

Please light me what I am missing in this config.

Try this...

Try this...

In callmanager goto the Phone Configuration page and scroll down to the box called Protocol Specific Information. In that box is a field called SUBSCRIBE Calling Search Space. That field needs to be populated with an internal network calling search space. This will enable the indicator lights for your BLF entries. I hope this helps. Have a Great Day!
