Hi,

I have a client who has been working fine for months, but as of late they are reporting connections where the audio only works in one direction or neither and “terrible echo”.

I know they had some issues with their local Cable Connection, but they are supposedly resolved.  Results from “ping –n 50 –l 256 ” and “tracert” are virtually identical to mine from here and I have no issues.   Are there some diagnostics I could run to try and pin this down.  The phones are all cisco 504Gs, the server is a VPS from synapseglobal.

Thanks for any ideas you may have.

Sean
