There are probably two flavors of Initiate:  One where the INVOKE
specifies a dial string and one where it specifies a URI.

I don't think this is a separate operation.
If the intention is to join *at a remote UA*, then this is just an Initiate
where the request-URI is "sip:foo@bar?Join=xyz".
If the intention is to initiate a new dialog, but have it joined *at
this UA* with an existing dialog, it is a form of the Conference

Please use a 4xx response!

This assumes that the phone knows the proper VM URI.  It also assumes
the user is configured so that the next destination of the call is a
voicemail system.

Aren't "Decline" and "Send to VM" related to the ACH proposals?
