Cisco BLF Not Working

Experts,

We are running CCM 6.0.1 and the majority of the phones in our office are 7960. We just added some 7962 phones and I'm trying to setup the busy lamp field to see when a particular person is on the phone. I have created the BLF according to all documentation I can find, and it just doesn't work. It doesn't do anything when I know that person is on the phone. If I press the button once, it does call them, so it is the right extension...

Is there something else I need to setup here? Permissions?

Thanks in advance.

You have to enable "allow subscription" is set to "true"  in system>enterprise paramemeter>presence.

Also you have to apply  subscribe Calling search space on the phone on which you configured the blf speed dial ,This CSS should have  the line partition which is used in the line which you want to monitor.

I think I found the main problem.... Presence isn't even turned on from what I can tell. That option isn't even there... Guess I'll look into that first. Thanks

Scratch that post - I think I found what you're talking about, but was under service parameters rather than enterprise paramters. The setting is Clusterwide Parameters(System - Presence) -> Default Inter-Presence Group Subscription  -- this is set to allow subscription. Is that what you're talking about or something else?

Yes, the device CSS does have the Internal partition.

Quick question are you sure you have it configured as an extension instead of a speed dial?  BLF will work when it is an extension.

I have it configured as a speed dial BLF. If there is a better way, I am all ears.

As part of testing just put the line appearance on the phone and then test.  The issue you are looking at seems like a partition/css issue.  Make sure both phones and lines are in the same css/ and partitions for both lines and phones.

I will do that. Bear with me - I'll have more time to look at this tomorrow.
Unless something changed recently that I don't know about, every device is on the Internal partion, which is a part of all available CSS.

I found that the subscribe css was set to none under the presence settings for both of the phones in question. I changed that to the same CSS as the device. I'm not in the office this week though, so I can test this next week. I'll let you know asap

That should be it.  The problem you were describing was indicative of a css issue.

Changing that setting didn't appear to work at first. I had to go into the directory number and add the calling search space to the "Monitoring" CSS field. Now the icons appear different on the phone and appear to work!

Thanks everyone for your help, I'm glad this was an easy one.
