Hello all, I have an issue regarding an Avaya B169 conference phone. When we try and make conference calls it gives us a "wave off" sound that makes the "dee-doo-dee d00" tone. I called Avaya and they said it was a permissions issue but I am not sure where to look for this. The Avaya phone system is a 500 V2 system, the phone manager software is 9.0.6. Any help is greatly appreciated, thank you
