Hello All, When I disconnect a call from callee side. FS Send the BYE to Kamailio PUBLIC IP instead of Private IP. So Caller is not able to receive BYE. *# Call Flow:* *Caller User -----> Kamailio(Bind on Private IP) ----> Freeswitch(Bind on Private IP) -------> Kamailio(Bind on Private IP) ----> Callee User* *Kamailio Public IP:* KAM_PUBLIC_IP:9000 *Kamailio Private IP:* 172.28.198.123:9000 *FS Private IP:* 172.28.198.128:5060 How to resolve the issue? Please find attached SIP Message and Sample kamailio.cfg. In advance Thank you. -- Regards, Suresh Talasaniya. Contact : +91-9724264776 Skype : suresh.talsaniya
