PR Agency Calysto Communications Helps One of its Newest Clients, Endstream Communications, Unveil its New Mobile Dialer Application

Calysto, which is supporting a full-scale public relations program for Endstream, hits the ground running by managing a new product launch just days after kickoff

ATLANTA (April 26, 2011) – Calysto Communications, a global public relations and social media marketing firm focused on the communications industry, today announced that it is managing a full-service public relations program for Endstream Communications. The first task: Getting the word out about Endstream’s new mobile dialer application, StreamDialer.

StreamDialer is the mobile extension of Endstream’s proprietary routing technology, which allows wireline providers to maintain their subscribers on the mobile network. This allows all calls to be billed back to the customer’s wireline service provider, enabling wholesale telecom service providers to retain customers that they otherwise might lose to mobile providers.

It also allows an enterprise customer to initiate a call on his or her corporate WiFi office system and then leave the office without the call being dropped. In other words, the StreamDialer application enables seamless handoff between wireless systems.

Calysto is managing a wide range of public relations activities for Endstream, including messaging, the development of press releases and other written materials, speakers’ bureau, and media, analyst and blogger relations. Calysto will also play a key role in developing and executing social media strategies for Endstream designed to help the company build on its current social media presence, such increasing its Twitter following.

“Less than two weeks after our kick-off call with Calysto, the Calysto team had already helped us fine-tune our messaging for our StreamDialer mobile dialer applications and had booked five briefings on StreamDialer with key media and analysts,” said Erik Levitt, Endstream CEO. “It’s a big part of the reason we hired Calysto. We knew the agency had the experience to get our public relations program up and running very quickly.”

“When I first met with Endstream, I knew we could help expand awareness of its new StreamDialer mobile application almost immediately, thus helping it to reach a totally new set of potential customers,” said Laura Borgstede, Calysto CEO. “One of our critical next steps is enhancing the company’s social media strategy, and we have a proven track record in helping clients build awareness through social media as well. For example, Calysto helped one of its client increase its Twitter followers tenfold in just 5 months.”
