First you have to find a SIP client which supports this feature.

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.

    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
