Question about SIP to PSTN cause mappings

This may be a dumb question, but my knowledge of e&m signaling is limited, so here goes. I am using a 3845 as a voice gateway, with T1 CAS (e&m-wink-start) on one side and SIP on the other. If i place a call to one of the SIP phones and it returns a 486 busy here SIP message to my 3845, does that 486 get mapped to a pstn cause code of 17? And if so, does that 17 get indicated back upstream on the CAS T1? Any help would be appreciated. Thanks.

That's the default mapping of PSTN Cause Codes to SIP Event Mappings -- so if everything is configured properly (and someone hasn't changed the mapping), Yes.WRKNonCCNP wrote: »does that 486 get mapped to a pstn cause code of 17?
