Cannot see my conference list on 7970 phone on UC520

[kseewald]

I have a UC520 with a lots of 7975 and 7970 running. I am able to create conference,

but when I want the see the conference List pressing the button I don´t get any result.

Does anyone can tell me how to look on this or make any traces?

Best Regards
