ABSTRACT:
A system and method for allocating vocoder resources for interconnect calls includes consideration of whether an interconnect call request occurs during a known period of heightened network activity. In an embodiment a vocoder type is assigned to a given interconnect call based on a comparison of the available capacity of the telecommunications network to one or more threshold values, and a determination on whether or not the telecommunications network is in a predefined high activity or usage period. In certain embodiments, the vocoder is adapted to operate in one of two possible types, where the first type is characterized by a higher voice quality, but a lower network capacity, than the second type.
