I have thought about this for supporting CNAM lookups. (Our carrier
doesn't supply callerid names to us.) I've been thinking of using a
b2bua, and sending INVITE/Replaces. Problem is, I need to get Asterisk
to send the update through to a phone. :-(

Hi JAvier!
Do you mean to update the Display of the SIP client during a call?
This is not defined in SIP. According to RFC 3261 it is forbidden to
change the From during a a dialog. Thus you can't change the display
name int the dialog.
Maybe you can send reINVITEs with different P-Asserted-Identity
headers whose Display-Name portion gets updated. But it depends on the
client if it will the data from the P-Asserted-Identity header of if
it gets updated on changes.
