Has anyone experienced issues with vmd or dtmf with Verizon wireless?  I have another script that doesn't even register digits pressed -- it's like no keys are pressed at all.

I've checked the FS log and it doesn't seem to log anything with regard to the mod_vmd other than an indication of MIN_TIME of 8000 (not sure what that does exactly).

Does anyone have any sample scripts available other than what's on the FS wiki?

I've got the following Lua script working in a sense, but the InputCallback never seems to get called while the file is being streamed to the call recipient.  I've tried moving the "vmd start" command and set input callback around a bit, but to no avail.  I'm testing this against a cell phone voice mailbox (Verizon).

freeswitch.consoleLog("info","########################################################\n\n");

number_to_call = argv[1]

        freeswitch.consoleLog("notice","************ VOICE MAIL/ANSWERING MACHINE DETECTED *************\n");
        voicemail_detected = true;

    end
end

function playbackMessage()
    sleep_time = 1000;
    if(voicemail_detected) then
       sleep_time = 2500;

        session:answer();
        session:setInputCallback("onInput", "");
        session:execute("vmd","start");
