Change the way you feel about Telcos and customer service

  • Fantastic customer service. Friendly and efficient staff. Excellent knowledge of 3CX Phone Systems and VOIP telephony.

    AMANDA MILLS | TAITS LEGAL

  • The technical and professional staff at C2 Communications have been extremely helpful in getting our entire IT&T networks to work smoothly and effectively across several Melbourne offices. With the high volume of telephone calls made, we have certainly benefited economically with the decision to install 3CX. The IT team has been highly responsive and we would not hesitate in recommending both their IT services and VoIP solutions.

    ANNE LAMPE (née Smyth) | LAMPE FAMILY LAWYERS

  • I had not seen an install of a phone system undertaken with such efficiency and speed, until the team at C2 Communications installed our 80 handsets/extensions in only a few hours. Our VoIP service has worked smoothly ever since and we can manage it internally without the need for specialist PBX technicians.

    JARLATH LEYDEN | ROTHELOWMAN

  • C2 Communications installed our 3CX phone system and it works seamlessly between our several sites. The changeover to using SIP lines has proven to be extremely cost effective. After the installation, our staff were trained on how to manage the system internally and we are particularly impressed with its reliability and functionality. It’s definitely been a positive move for our business.

    LANCE DIXON | LANCE DIXON PRESTIGE MOTORS

  • We’ve had these guys looking after our phone and I.T. needs at work since 2010 and they’ve always been fantastic. Service is always spot on and they’ve never let us down. I won’t even speak to any other company trying to poach our business.

    MELISSA JOLEVSKI (née Hart) | MANARK PRINTING

  • We’ve had the 3CX VOIP phone system installed for a number of years, and we’ve been impressed by its versatility to expand and adapt with our growing business. The team at C2 Communications are easy to work with and very flexible in their approach.

    PETER BAILEY | WYNDHAM CLINIC
