The agency has been appointed to a UK and EMEA media and analyst relations programme. It beat Companycare,
Grant Butler Coomber and the incumbent, Noiseworks, to the account. Noiseworks had held the account since 2001.
Sonus Networks marketing director EMEA Paula Lender-Swain said the provider was ‘very well known in the US and Japan'.
She added: ‘We are the market leader for VoIP globally - our nearest competitor is four times smaller than us. So the next step is to build brand recognition in EMEA'.
Lender-Swain said that France and Germany would be particularly important for Sonus Networks, and that business and trade press would be important targets. She said that Catalysis had been hired because of their ‘deep understanding of issues-based PR'.
Catalysis director Suzy Insley, who leads the account, said: ‘Our aim is to help Sonus Networks raise its profile in the European market place following recent deals with major European service providers including Opal Telecom and Cable & Wireless.'
SEPARATELY... Catalysis has also been appointed by wireless hotspot access provider Trustive. This is the first time that Trustive - which has a network of 20,000 hotspots that allows increased WiFi internet access in places such as airports and petrol stations across the world - has retained an agency.
