One of our users (and I believe others have expressed this issue before) is having people on the other end of the phone hearing buzzing. The audio sounds fine to her though.
The SPA504G is using load 7.5.2c on a UC500.
The only thread that seems similar is this: Buzzing noise from the IP Phone, however, that is dealing with 79xx phones.

How does the UC500 connect to the PSTN?

A PRI. But note... this is only when on speakerphone. When on the handset, these issue do not occur.

Is this using a SIP or skinny load on the phone?

Skinny/SCCP. Also it's CME 8.6
