[SR-Users] Kamailio NOTIFY

Hello all. I'm having problem with sending NOTIFY packet for event dialog. The problem is, that all NOTIFY packets sent with this event is empty. ( Content-length: 0 ) and in fact, not passing actual status to the phone. In my case this is SPA962. NOTIFY packets for event presence are sent fine and status is changing normally. The same phone, works fine with Asterisk. Asterisk is sending NOTIFY with non-zero content and changing status for the subscriber as well. I've turned on pua module to send PUBLISH requests at Kamailio, it's filling DB table with subscription, everything runs fine and NOTIFY packets are coming to subscribed phone, but they are empty. I also have presence_dialoginfo module on and pua_dialoginfo module on. I've tried on Kamailio 3.0.3 and 3.1.1. Content always empty. There is no sense of pasting here packet dumps, cause everything is like should be: (UAC) SUBSCRIBE, event: presence ---> K K ---> 202 OK (SPA) SUBSCRIBE, event: dialog ---> K K ---> 202 OK PUBLISH, event: presence ---> K K ---> 200 OK NOTIFY, event: presence, Content-Length: XXX ---> UAC NOTIFY, event: dialog, Content-Length: 0 ---> SPA962 As result, softphone changes status and hardphone ( SPA962 ) - no. May be it's cause of PUBLISH event value? Please advise.
