Have the number of available voice devices been built around the NAA device count?
A. The catalogue item provided to a site is dependent on the National Allocation Algorithm) (NAA) device count and local requirements. Each catalogue item has a number of associated voice channels and the voice service offerings have been designed around the number of available channels.
