Hi all, I am using pjproject-1.1, and I enable the sending of PUBLISH and SUBSCRIBE packages when REGISTER success. Now I can receive and parse the NOTIFY packages in the Dialog of SUBSCRIBE, exactly it call the callback method: pres_on_evsub_rx_notify -> pres_process_rx_notify -> pjsip_pres_parse_pidf -> ...and so on to parse the XML data. But now I have problem to act with NOTIFY event, I do not know how to send such event to my IM Client so that it can change the buddy status after receiving the NOTIFY package. Can someone tell me how to do it? Thanks in advance! Regards, xutm -------------- next part -------------- An HTML attachment was scrubbed...
