I also have a bad echo problem with a BCM50 with analogue lines.
The digital phones work fine, outbound calls sound great.
The problem is with the IP phones I am testing.
i2004 (4)
NTDU92BA70
Firmware: 0604D4B
I have taken the entire LAN portion out of the equation. The phone is plugged directly into a LAN port on the BCM50. I have the phone hard coded to 100Full. I have tried new patch cables, different phones, etc.
Internal calls sound OK. (No echo at all)
I have also set the codec to G.711-ulaw and the jitter to Auto. Echo cancellation is enabled in the media gateways section.
Changing the codec from Auto to G.711 helped a bit, callers say I sound "clearer" but only I can hear a consistent echo when I talk.
As soon as I connect to one of the analogue ports and get a dial tone, if I start to speak the dial tone dims down until I stop talking. Then it goes back to dial tone. As soon as I connect everything sounds clear until I start talking, then I get to hear myself repeating everything.
Connecting a regular pots phone to the lines has no echo as well as the digital sets which I mentioned.
I have a feeling its something simple I overlooked, but I would appreciate a help in the right direction.
Thank you very much!
