OnMobile Global announced Friday the launch of High-Definition (HD) Ringback Tones for 4G Voice customers and a new application called Identity for Vodafone Spain. OnMobile has helped Vodafone Spain leverage Ringback Tones to increase the awareness and adoption rate of Voice over LTE, the company said.

OnMobile has encoded High-Definition Ringback Tones in AMR-WB (Adaptive Multi Rate-Wide Band) format. The OnMobile solution enables Vodafone's Voice over LTE (VoLTE) service users to experience high audio quality, thereby improving consumer experience and stickiness.

''The deployment of our service on 4G Voice is a significant milestone for OnMobile as we are now able to offer customers their favorite music in high-definition audio. The launch of Ringback Tones in High-Definition, coupled with the Identity app, reinforces the global appeal of this service. The 8-10 second interval that a user takes to answer a call is a shared communication space that can be customized in many ways,'' said Sanjay Bhambri, chief commercial officer, OnMobile.

Shares of the company declined Rs 3.35, or 3.1%, to trade at Rs 104.80. The total volume of shares traded was 511,064 at the BSE (2.14 p.m., Friday).
