I have an LTE7480-M804 modem (external). I have just updated the firmware to 1.00(ABRA.6)C0 and am trying to get my voip phone working. I have seen on the manual that there is supposed to be a voice mode (see manual page 17.2 at

There does not appear to be any such option and I am wondering (a) if I have an old model which does not support this feature (and if so how do I get the voip working) or (b) if I need to update the firmware to a more recent version.

Any help appreciated.

    Hi Patrick,

    Here is a foot note in the beginning of that page which describe as follow.

    Note: This feature is only available on certain models. For details, see the features comparison

    table at Section 1.1 on page 16.

    When I check Section 1.1 on page 16 that LTE7480-M804 did not support Voice feature.
