Hi Paul,
there are several ITU-T Recommendations:
P.340 (08/96) Transmission characteristics of hands-free telephones
P.341 (04/95) Transmission characteristics of wideband hands-free
telephones
P.342 (08/96) Transmission characteristics of telephone band (300-3400
Hz) digital loudspeaking and hands-free telephony terminals
Maybe that's what you are looking for.
Regards
Volker

I am interested in knowing if there are any publicly available Handsfree
Speakerphone performance specifications, test standards, and/or testing
guidelines.
I would greatly appreciate any responses. Please send them to
[email protected]
Thank you.
Paul
