What I need is that Display Name works in the same way that Presence State. I mean, when an user changes his status, he send a PUBLISH to the openser, and it send a NOTIFY to he users that have already suscribed.

best regards

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
