Hi,
I am getting static on UC520 MOH, internal & external calls, IOS version is 12.4(20)T2, just using g711 codec as single site.
Thanks

Sounds like it could be a problem with the connector on the UC520. I would recommend opening a case with TAC to see if they will RMA the unit.

Is MOH being played from a file on the UC520 or an external source? If a file, copy the file off to a computer, play it and see if it has static.
Hope this helps.

Hi Brandon,
Thank you for the reply, I am using itouch as an external source, if I switch to flash source it is fine, do I need to use a certain kind of jack with itouch ?

No, any 3.5mm connector should work. Have tested the itouch with headphones? Is the audio OK? If this works, try plugging the itouch into external speakers using the same cable that is connecting it to your UC520. Any static? If not, this should rule out the cable. The last variable would be the connector on the UC520. If possible, try plugging another device into this connector and see if the problem remains.
Hope this helps.

Brandon,
sound from external speakers is good, changed cable has no effect, as suggested connected another itouch still hear crackling sound.

I took out itouch from the port and I still heard the crackling sound, then I shut down voice port 0/4/0 and the noise went away, it confirms that it is the voice port. I will move itouch to the fxo port tomorrow and hopefully won't have any noise, will update.
Thanks for all the responses.

Make sure you use a mono plug, if it's a stereo it will not work.
