>From an Avaya switch documentation:

"80 millisecond (ms) to 180 ms delay can give quality business
communication, which is much better than cell-phone quality. This range is
very well suited for the majority of businesses.

The International Telecommunication Union (ITU-T) recommends 150
milliseconds one-way delay (including endpoints) as the limit for
³excellent² voice quality. This value is largely misinterpreted as the only
measurement to calculate a network delay budget for IP telephones. One-way
delays in excess of 250 ms can cause the well-known problem of ³talk-over²,
when each person starts to talk because the delay prevents them from
realizing that the other person has already started talking."
