Cisco Router 887 and Polycom HDX Issue One Way Call
Please help me to solve a weird issue. I have 2 office Main and Branch Office.
At the main office, we have installed Polycom HDX 8000, connected to a internet router and having static public ip address.
At the branch office, we a have client behind the router. This router is Cisco Router 887VA with a PPPoE ADSL connection. The router is configured with NAT. So the clients behind router are NATed when going to internet.
This client having Polycom Real Presence Software installed on his laptop and making h323 call to connect HDX at the main office. The call is established. However, the client cannot see and hear the person at the main site. The main site can see and listen. So its a one way call.
But after changing the router at branch office to Cisco 1841 IP Base License, it just works fine.
