It was the start of a relationship that has stood the test of time. It has also thrived through considerable change on both sides. In 2015 the Council had a major data centre transition. In the same year the M2 Group acquired CallPlus. Six months later that company merged with Vocus Communications.
Hamilton City Council chief technology officer Pieter Bronkhorst says all those changes passed with minimal disruption. He says it helps that the relationship goes back a long way: "CallPlus was our landline and SIP provider before it became our total telephony provider in 2013."
Bronkhorst says: "We had a very strong relationship with the account managers and with senior management. This helped us. If you've got a good relationship and customer engagement, then individuals can absorb whatever changes. They just continue to deliver service consistently while they deal with all the structural changes.
"When there were new personnel, the transitions were always handled smoothly. Vocus would send a senior manager who would come along and explain what was changing and how they would deal with it.
People are central to any business relationship. Bronkhorst says the chemistry between Hamilton City Council and Vocus was good from the outset.
