Unified Communications


With the advent of VoIP, businesses have become more reliant on their networks to carry critical voice and collaboration services. CACI’s combined experience in both Network and Unified Communication enables delivery of Enterprise graded services across any sized organisation. Our teams are currently supporting major systems within Banking, Telecoms, Utilities, Property Management & Regulatory customers.

We can provide an end-to-end service; starting with strategy and design, holding your hand through implementation and finally providing ongoing support. We offer a wide range of solutions from traditional voice platforms, to both hosted and onsite Unified Comms systems and, whilst we specialise in providing professional services on Cisco and Microsoft, we do also provide resource to migrate Nortel, Ericsson, Mitel, amongst other vendors. 

CACI has highly skilled staff working in engineering and project/programme management who have an understanding of the businesses needs rather than just the technical capabilities. This, combined with our an extensive portfolio, ensures that Unified Communication is an enabler rather than a burden. 

CACI has a UK based team who regularly work across the world as required by our international customers, fulfilling deliverables against comprehensive scopes including project such as:

  • Cisco HCS global delivery

  • Cisco UCM upgrades

  • Cisco UCCX implementation

  • Cisco Presence implementation
