Abstract

Information systems infrastructure is increasingly being used also as a backbone of telephone systems. This is result of VOIP-based telephone systems which replace analogue PBX centres in organizations. IT departments are in pressure-not only do they need to verify the existing infrastructure, make development plans, investments and implement more advanced devices but also they will be acting as phone support personnel.
