As far as Pakistan is concerned, analog exchanges have been wiped out 
totally and have been replaced by digital exchanges with all the typical 
value added services and features. The impulse of change-over from 
analog exchanges to digital exchanges had its roots more in curbing VoIP 
termination than a genuine technical aspiration to move from EMD 
exchanges to Digital Exchanges.
