Echo problem on Elastix 1.5-2 with DE115P

you should set the echocancel=no, because the default value is yes.
Then system.conf:
loadzone = (your country)
default = (your country)

indications.conf
country = (your country)

I will try that tomorrow,

Thanks

Hi again

I set echocancel=no in chan_dahdi.conf, but the echo persist . Another thing to do?

Regards!

Hello
You mention the PSTN persist, what does it means? Are you refer our manual to install your system? There is a manual of installing DE115P. Please make sure follow our manual to install.
