[SR-Users] AVPs missing in onreply_route

Hi, I'm still fighting problems in our Kamailio 1.5 to 3.1 migration. Right now I'm stuck with a strange behavior of AVPs in my dialplan. I set a lot of AVPs for accounting in the route directive, and I just inserted an avp_print() statement right before t_relay() is called, all values are set. Then I call avp_print() as the first statement of onreply_route(), and it doesn't print out anything. I call it again at the end of onreply_route, and the only AVP printed out is the one I set directly there. In 1.5 there was an option in the tm module to control AVP behavior in replies, but that doesn't exist anymore, I even found a mailing list post from Daniel where he explained that all AVPs I set in route are also available in onreply_route. Am I doing something wrong? Is there still a secret option that I accidentally turned on? What else could make kamailio forget all AVPs after t_relay? I tried both version 3.1.3 and 3.1.4. Any help appreciated. Best regards, Sebastian
