8310 - Sounds like a fax machine on answer

[TheSMan]

Has anyone else had this problem?

When I (or anyone else) ring my girlfriend's 8310 when she answers it makes a funny high pitched squealing noise, similar to the noise you get if you dial a fax machine. It disappears then comes back intermittently during the call.

Any ideas on a cure?
