I'm on RH9 Stable v1.4 Version, using an old TMD400P digium card. They are some situations when I received echo on my cisco phones: 1- Some users or PC is dowloading some files from the network. 2- A call comes in from a cell phone. 3- A international call is received on our Asterisk Box. 4. We have a separate legacy PBX that on some circumstances need to tranfers call to asterisk. Most of those calls are received with echo. Besides this, is about tuning the rxgain,txgain usually on a range of 1 - 3. and to be sure your Digium uses it's own IRQ. using "LSPCI"
If someone could explain to me a way to improve or solve the above items, would really appreciate.
