    Hi,

    I use 3 different providers that claim to support T.38 but with all of them I unable to send faxes :(
    either I got error "No RTP packets were received" or "400 Bad Request".
    One of providers lets to choose fax mode T.38 or transparent. Neither works with the same error "no rtp packets.."

    From a provider's support I received this:

    > We need 3CX to initiate a G.711 call and then send a reinvite on T.38.
    > We are not that familiar with 3CX are you able to ask 3CX support if this is possible?

    Is it possible to configure lake that?

    Please, give me a hint! I've spent 3 working days on this, and have no idea any more :(

    Some logs:
