The standard jack for telephone handset cords is an RJ-9. Along with
2.5mm and 3.5mm headset jacks, I'd like to see the RJ-9 included in the
list of acceptable audio connection points. Thanks,

2.2-C - Audio Connection
When products provide auditory output beyond simple tonal feedback or
signaling, the audio signal must be provided at a standard signal level
through an industry standard connection that will allow for private
listening as follows:
* Products designed to be located in public places must provide
connection via a standard 2.5mm or 3.5mm audio jack at the standard
signal levels used for headphones/headsets.
* All other products can use any connection method as long as long
a 2.5mm or 3.5mm phone jack adapter is available from the manufacturer
or commonly available.
