Polycom VSX 7000 cannot recieve calls

Hi I have a Polycom VSX 7000 can make outgoing calls but cannot recieve incoming calls.  We do not have a firewall and the polycom system is connected to a modem.  When the farsite tries to PING with our system they get a response back but when they call all they get is ringing.  I never recieve the call.  My ports are not fixed, and NAT is set to manual.

 

Please let me know where the problem may be.

 

Thanks

Sounds like somewhere inbound port 1720 is being blocked.
