Host pin invalid

from a poly ip conference phone i can join the meeting , but when i try to enter the host pin, get back invalid pin. I can join from desk phone and its works. any ideas on this.

seems need to wait just a few more seconds with poly conference phone before entering host pin and can start meeting as the host.

great that you found the solution. It is a bit strange though. We are listening for the incoming digits simultaneously with the first prompt. May be VoIP line has a delay on when it starts sending RTP out …
