Echo issues

Phones - analog, Polycom & Aastra
I have allot of echo through my * system and can’t seem to find a fix? The echo is present with inter-office calls but much greater with calls in or out to the PSTN.
For a PSTN connection I have a TDM410P connected to an analog line from my provider.

Where do I find the options to help fix this?

Chers!

Where you fix it depends on where it is being generated.

If it is on the analogue interface and these are real Digium TDM410s, you may qualify for support from Digium. (This forum is a peer support forum for open source Asterisk.)
