Have a CM, 6506 w/ a 6608 blade (used for conferecing) and a AS5300 all with public IP addresses.
I have an IP phone at home using a 17xx router (IOS 12.1(5)T) with a dial-up connection to the internet - been using this for many months. IP phone is on private address (router using PAT or overload NAT)
Just added the 6608 and finding that when I attempt to conference on another party (either another IP phone or a PSTN call) my IP phone on the private address loses the receive voice path.
Everyone else can hear fine and they can hear me fine - I cannot hear anyone..
Thinking that the voice path from the 6608 blade is not being handled properly by the PAT.
Thoughts?
