It is impossible for a SIP UAS to 'ignore' a '486 Busy Here' response. 
SIP phones are not dumb devices like traditional PBX phones, they are 
completely in control of their end of the call. If the phone sends a 
'486 Busy Here' response, it has already dropped the call.

It *is* possible to disable quite a lot of Polycom phone features via 
the configuration file; I would suggest spending some quality time with 
the Administrator's Guide (and ensure you are running 3.x software on 
the phones) to find out if those features can be disabled.
