INFO Use case

Let's imagine that there is a base DTMF package defined that supports  
the 12 basic keys. Now cisco makes a vendor specific package that is  
pretty much the same but includes key presses for the  "HOLD" button.   
Nortel does pretty much the same but calls it the "F1" button. Now  
SNOM wants to build a phone that supports both and in fact is  
operating in an environment with a Nortel PBX, Cisco Voice Mail, and  
Asterix SBC which understands both - the phone really needs to send  
both and they need to be one atomic action so they are not interpreted  
as the wrong thing or as double key presses.

It seems that things along the lines of the above will happen and need  
to be considered. I don't know if this means an INFO needs to carry  
more that one thing or not. The worst possible solution I can imaging  
to this is that SNOM builds a new package that combines the Cisco and  
Nortel package.

PS - I do not care if people want to solve this use case or not. I  
just mention it as something I view as somewhat likely to happen. I am  
happy with whatever get's decided.
