    Hi @Spiro

    For check the symptom more details, you can send the WAN and LAN packets by private message to me.

    Hi Stanley,

    Has this issue been resolved?

    Can you share a how-to?

    This is a very common issue.

    We work-around it very often by asking to change from SIP over UDP to SIP over TCP.

    But I have not had any luck in getting WAN and LAN traces before and after to find the root cause.

    Best regards,

    Alcindo
