One of the world's largest global financial institutions retained PSS to help them transition from legacy IVR systems to next-generation IP-IVR systems in all of their international contact centers. They selected a VoiceXML-based IVR system from Holly, which natively supports a VoIP/SIP telephony interface. The customer also selected an industry-dominant gateway vendor to provide connectivity between existing TDM switches and the new IP-IVR.
