[cisco-voip] Conference Softkey Grayed Out

[tomlemay at adelphia.net]

I have one  Cisco 7960 IP phone which has the  conference softkey feature button grayed out when in an active call.  thus, the user is unable to conference a thrid caller onto an active call.  Has anyone else  seen this behavior?  I have checked media resources adn that is correct and I have  checked the softkey template and that is correct.  I have compared this one odd phone to another phone and the profiles match.  I would apprecaite  any insight on this issue.

Thanks,

Tom
