Good morning,

I have a OpenVox A800P with 8 FXO ports, a system installed in Elastix 64 bits

the problem is with incoming and outgoingcalls, this calls presents a lot noise you hear on both sides of the call.

It is an interference noise, the noise is like the wiring made ​​false contacts, I given that connect a conventional telephone line and the result was excellent call quality, so I can only ask if there is anything I can do to configuration level.

I read some things in connection driver and even something called OSLEC, I would like to receive guidance in relation to this issue.
