    Hi @Suy Peang

    To troubleshoot this issue, we recommend you check it from the following ways:

    1.Firewall ports: please make sure you have opened these ports (UDP 3478, TCP 443, UDP/TCP 50000-59999). The following picture shows these ports for your reference:

    2.DNS Records: please make sure you have these records(access.<sip-domain>, av.<sip-domain>,conf.<sip-domain>) on your edge server.
