    Hi @CHRISTIANP,

    Thank you for visiting SonicWall Community.

    Was this VoIP setup worked prior to the firmware upgrade? Could you please check the SonicWall logs for any error messages? Also, I would suggest you to perform a packet capture on the SonicWall based on phone's IP address(es) or port numbers.


    Regards

    Have you tried to disable sip alg? My supplier of the sip line pointed this out.
    I had the same issue and uploaded the previous firmware version to het it working and have not tried this solution yet. https://www.sonicwall.com/support/knowledge-base/how-to-disable-sip-alg/210615065648977/

    Was it an upgrade?

    Hi @ChristianP

    Try disabling sip transformations, enable consistent NAT, and disable UDP flood protection.

    We have the same issue after upgrading to 6-5-4-8-89n yesterday night on one of our customers NSA2650 Clusters.

    The VoIP provider confirmed that sip registration stopped working the second we installed the update.

    When we do a WAN failover, sip registration works but the customer cant hear the other side.

    Gonna open a case for this too.

    @ChristianP and @EF999

    It has been a month - could you please update status on either support's conclusion or remediation for this issue?

    Thanks!
