edge dns load balancing connectivity problem

[phonetech1]

Hi,
I have a lab deployment of lync2010 enterprise with dual FE and dual edge servers.
I'm having intermittent problems with external clients making calls to internal clients.
The address book is working and I'm able to call internal to external or external to internal. The call rings in and after clicking on accept a call the client shows trying to connect and after about 20 seconds disconnects and shows "call failed due to network issues". Everything works fine if only one edge is up, doesn't matter which one. I can bring a second edge up and for a while everything would still be working but after a while the problem would come back.

Thanks

Have you looked at it in Snooper? I would start there and see what gets logged when it fails.
