Re: [Freeswitch-users] Lua Script with mod_vmd, setInputCallback doesn't seem to get called

4 Mar 2010

      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).
