The only response that seems to have any real logic in it is this... - The TDM card seems to have the hardware facilities (eg, chipsets) on it to do substantially more then what it is today - There are very few * developers that truly understand the low level pstn interface requirements necessary to code additional functionality into the TDM drivers - Mark is one of the few that can translate pstn interface requirements into real code, and his time seems to be distributed across a lot of different areas (not sure when he gets to sleep) - the overall design of the TDM card relies on the host system processor to interpret dtmf tones (from digital pcm data flows), etc. Therefore adding functionality to the drivers is a delicate balance between the function and burning host cycles that might be disruptive to other * components - detecting dial tone before dialing would seem to be trevial (I can easily say that as a non programmer), but someone needs to add the code to do it reliably - the chip set in use already has provisions to detect CO battery, line off hook (presumably from a bridged analog phone), battery reversal (supervision), etc, but someone needs to add the code to use it. Best guess is time constraints are having "the" biggest impact. The unwritten default condition for * development is that if a feature or bug fix is expected/required, there is a high probability it won't be addressed unless a bug report is generated, or, one of the developers has the same problem; sort of the squeaky wheel gets the grease. It's my belief (right, wrong or indifferent) that digium is missing out on a major revenue stream due to a lack of understanding "marketing" and the prioritization of certain development functions (like the above) required to sustain/grow sales. If digium is going to rely on the sales of these cards to grow/support *, then something is going to have to change since user experience/opinion for those products is heading in a downward direction (not upward). I'm certainly not ragging on anyone, just stating an opinion FWIW.
