  2. 2. CheektowagaObjectives:Replace an end-of-life Nortel® analogtelephone system (that is patched withequipment from various vendors) witha web-centric VoIP infrastructure toreduce communications costs for thisNew York municipality. The projectincludes designing and implementinga VoIP infrastructure for 500employees in 15 separate locations,including the mission-critical policedepartment; the town hall campus,which contains six buildings; and thecore location on Alexander Street.
