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.
I'm thinking this is an argument against a vendor tree and in favor of
a spec-required policy that allows minimal specifications.
