Hello I'm getting the error "cannot complete conference" on my Cisco phones. This started after I configured the Meet-Me feature in my CME. I thought I was out of resources so I added a new PVDM2-16 only for Meet-me. I know the problem is a configuration parameter but can't get it to work.

Here's the config parameters:

!
voice class custom-cptone leaving-tone
dualtone conference
  frequency 900 900
  cadence 150 50 150 50
!
voice class custom-cptone joining-tone
dualtone conference
  frequency 1000 1000
  cadence 150 50 150 50
