I'm currently testing an SPA8000 and I have background high pitch noise problemwith a GE analog phone when on speaker phone. The phone is directly connected to the SPA8000 with a 6 feet phone cable. I've tried the same phone on other units (Audiocode & Mediatrix) and I don't see the problem. I'm wondering if this is related to the load on the FXS channel. I saw on another forum that some unit have this problem and must be return for RMA. Anyone experienced the same situation? We might buy a lot of those if this is not too big of an issue.
It doesn't matter to which port it is connected. I'm not sure that I'm experiencing the exact same problem as mentionned in the tread but still, I'm a little worried about this issue. We're currently evaluating this device to replace the Audiocode and Mediatrix we're shipping to our customers right now. Beside this issue, the SPA8000 seems to fullfill our requirements.
