Hi! You could copy the PAI body into an AVP and then use pseudo variable transformations to parse the URI. uups - i just found that there is already a PV: http://www.openser.org/dokuwiki/doku.php/pseudovariables:1.2.x#uri_in_sip_r… But I do not know if this works with multiple PAI headers too. regards klaus Helmut Kuper schrieb: Hi, I'm playing around with RFC 3325 and P-Asserted-Identity (PAI) Header-Field. I found that openser 1.2.x doen't support PAI parsing, so that I don't have a fast way to access user and domain part of PAI. Is this planned for openser in the near future? regards helmut >
