We can hear/see them but they cannot hear/see us

We are a Cisco shop and using Polycom

Brand: Polycom

Software Version:Release 7.5 - 29 Sep 2003

I know it is pretty old but that is what all our sites are using.

We have connected up this unit to use IP and are connecting to other sites.

We can always see and hear them but all they see is a blue screen with name of the unit on it and they also cannot hear us. We have done a series of test,

dial tone

loop back test which has come back ok.

The strange thing is that another newer Polycom using is able to connect to these same sites and both was see/hear are ok. We are using the same WAN pipe.

No gateway, This is a point to point test just using the WAN Link.

Please help? What else can I do to troubleshot this and get it working?


I have this problem too.
