The creative shop will next focus on developing brand strategy and business-to-business marketing, particularly businesses transitioning into the cloud.
"We're excited to be working with FCB to build on the incredibly high awareness of the Vonage brand and extend the brand into business markets," Vonage Chief Operating Officer Joe Redling said in a statement. "Ultimately, consumers and businesses should view Vonage as one company, united under a single brand that provides communications solutions to multiple customer segments so they can communicate anytime, anywhere, from any device."
The agency was awarded the business without a pitch. "Our CEO Lee Garfinkel leveraged an existing relationship that he had with client," a spokeswoman said in an email. He had previously pitched the business in January 2013, while still at Havas.
"This is a fascinating company; a proven disruptor and innovator that has consistently enabled connections and brought real value to consumers," Mr. Garfinkel said in a statement. "Vonage has extended that same value into the business market, and we're excited to tell that story."
Vonage spent $96 million in U.S. measured media in 2014, according to Kantar Media, down from about $150 million in 2013.
