  • Hi,
    which kind of SIP Trunk do you have? Do you use an SBC? Please add more info on your environment.

    Thanks

  • Hi link user graded out,

    Please give us more information like Luca mentioned.

    You could try the following troubleshooting methods:

    1. Check your configuration for your SIP trunk.
    2. Please check if all users had this issue.
    3. Use Microsoft remote connectivity analyzer test if there are any errors: https://testconnectivity.microsoft.com/

    Hope this reply is helpful to you.


    Regards,

    Alice Wang

  • This is normally because of the gateway configuration.You may verify Early media or DTMF & Dialing settings in Gateway.But to confirm that more information required.
