Static / White Noise IP 500.......HELP going mad !

[cupra20v]

Hi guys

Not the first post i was hoping for but anyways, installed an IP500 (4.0.10) last week, with a mixture of DS5410 and IP6410. On DS to DS calls there is a background line noise on internal calls (external not linked up yet), IP to IP is fine, DS to IP is fine "ish", DS to DS being the loudest.

We have swapped out the IP500 control unit and DS30 module no joy still there, plugged the DS phones straight into the DS module, still white noise, to rule out cabling even thought the cabling has been certified CAT5 so wasnt expecting that to be an issue, the rack is grounded to their local distribution board earthing bar, and the IP500 and DS module earthed to the rack.

I would really appreciate some help / advice as im completely at a lost with it !

TIA

Thank you all for all the help / advice

I have tried turning off the AGC, if the volume on the handset is at its lowest its barely noticeable the static / white noise, move it up a few notches and its well noticeable.

As previously mentioned i have also been testing with the handsets muted and just listening, which is when its at its most noticable, and during silent moments in conversations.

Move to a different software rev, if that doesnt work, replace the DS30. Sounds like you have covered everything, move on.
