    Kamailio configuration 4 일 left
    확인

    We are currently building a Kamailio SBC which will be as Sip Proxy for our B2B, but we are facing a bug. Seems there to be a misconfiguration in Kamailio because when we are using a dispatch request, re-invite and ACK is not working to be sent in right way, because the re-Invite is sent back to dispatcher list which is making it lost and it is not forwarding to callee. This issue is mostly present at ACK and BYE. Hope some one can solve this and fix this SBC.
