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.
regards klaus
