The present document provides speech transmission performance requirements for 4 kHz narrowband VoIP handset and
headset terminals; it addresses all types of IP based terminals, including wireless and soft phones.
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.
It is the intention of the present document to describe terminal performance parameters in such way that the remaining
variation of parameters can be assessed purely by the E-model.
