polycom trio 8800 conference call no sound except last caller

[dolanf74]

Hi,

We have a polycom trio 8800 with last firmware installed.

When we make a conference call, then merge all participant.

only the last number called can participate.

the others do not emit sound, and do not receive sound.

I dont know where is the problem.

Does anyone have any ideas to help me with this problem ?

Thank you
