G114

ITU-T Recommendation G.114 specifies and evaluates the delay times and packet losses in packet-switched voice communication.Voice quality can be evaluated subjectively with the MOS value or objectively with the R-factor determined from test procedures.

ITU recommendation G.114 for delay times in voice transmissions

ITU recommendation G.114 for delay times in voice transmissions

According to the G.114 rating, voice quality is classified as unacceptable, still acceptable and good.

G.114 is titled "One-way Transmission Time" and specifies how much packet loss and delay is allowed for the G.114 rating. According to this, a packet loss rate of up to 5% is imperceptible and the delay time should be less than 150 ms for acceptable voice quality. If it is greater than 400 ms, the quality is unacceptable.
