Quoting claw on the Gizmo forums thread: "We are limited by the platform in this respect. The Nokia 770/N800 operating system is currently not capable of sending RFC 2833 signals. Nokia is aware of this shortcoming, but has not yet released an operating system version that can do this. (Sorry, but all we can do is ask Nokia to add this ability)" ref: http://forum.gizmoproject.com/viewtopic.php?t=5451 http://www.faqs.org/rfcs/rfc2833.html
This strikes me as kind of odd. The Maemo IM stack seems to allow for mixed video/audio/text, why is it that the Gizmo devs seem to think that the ITOS is incapable of this extra audio stream? I tried to bypass this missing functionality by generating some DTMF tones mp3s and playing them In-Band with the media player while Gizmo was placing a call. Unfortunately, Gizmo blocked the media player from playing the tones (while it did not block the little error tone that accompanied the error message telling me that I couldn't play my files). Even if it did work, I suspect that the iLBC codec would distort the DTMF signal horribly (thus the need for RFC 2833). Is it truly the situation that there is some missing link in the IM infrastructure on the ITOS that won't allow OOB DTMF? Is Gizmo or Media Player misusing the audio device such that they are blocking each other? I really think that this is important functionality for users as it pretty much blocks anyone from retrieving voicemail or using automated attendants.
