Speech and multimedia Transmission Quality (STQ); Transmission requirements for narrowband VoIP loudspeaking and handsfree terminals from a QoS perspective as perceived by the user

Scope

The present document will provide speech transmission performance requirements for narrowband VoIP loudspeaking
and hands-free terminals; it addresses all types of IP based terminals, including wireless, softphones and group audio
terminals.
In contrast to other standards which define minimum performance requirements it is the intention of the present
document to specify terminal equipment requirements which enable manufacturers and service providers to enable good
quality end-to-end speech performance as perceived by the user.
In addition to basic testing procedures, the present document describes advanced testing procedures taking into account
further quality parameters as perceived by the user.
NOTE: The present document does not concern headset terminals.
