    Hi,
    i have 3cx v15.5 (V15.5.6354) installed.
    On one iphone 7 i got this message:

    We have detected an old and unsupported version of 3cx phone system. This client will not run correctly with this version and will stop working all togheter on 1/1/2018.
    Please contact your administrator to upgrade 3cx to V15.5.

    I have uninstalled and reinstalled 3cx client on the iphone and resend configuration email with no change.

    How can i solve ?

    Thanks

    Have you changed PBX's User Agent? All 3CX clients perform PBX user-agent checking.

    No, it is a standard installation updated regularly since 15.0
    Anyway i made a check on the 3cx installation. In advanced config the parameter USERAGENTSTRING is empty.
    I mark that this client was correctly working on this iphone ten days ago and no updates have been made on 3cx system.

    What's the 3CX client's version - in More/Settings/About?
