This attribute specifies the amount of added output delay used to
compensate for cross network delay variations. It applies to voice,
modem and fax traffic. It is required to add output delay so that the
statistical variation in the transit time of cells crossing the network
does not cause gaps in speech. Backbone networks where high
priority traffic consumes a high percentage of trunk bandwidth will
require a higher insertedOutputDelay to compensate for the greater
cell delay variation (CDV).
This attribute is ignored if this call runs on a 1pDS1V or 1pE1V
card.
