    Did it ever work, or did it just stop working?

    What type of trunks are you suing for incoming calls and do they (the VoIP provider) support T.38 ?

    Earlier he worked. Incoming were accurate.
    Codecs g711. The operator says that supports T.38 available.

    If it worked previously, then what changed, at your location, just before it stopped?

    Get a wireshark capture, filter for SIP and examine the t38 re-invite. If you need help, post the capture here.
