When you set acc flag , it try to send radius request to configured server. Dont forget the configure radiusclient configuration. Ypu can find it on internet. Here is a document , it is old but helps https://www.kamailio.org/docs/openser-radius-1.0.x.html Good luck Yasin CANER iPhone’umdan gönderildi Yazar Lwin <yarzarlwin@gmail.com<mailto:yarzarlwin@gmail.com>> şunları yazdı (19 Oca 2019 14:36): Hi All, I've Kamailio 5.1 running with Mysql as local DB. I've configured Siremis as well. I completed accounting configuration as per the instruction. Now I can see the accounting list, CDR list and as well as missed calls in Siremis But I can't integrate with free radius server to trigger the accounting, just like Diameter transaction in IMS. Kindly advise which doc I should check. I would like to enable Radius server as an online charging.
