"We are talking to (potential) clients in India and a few of them have shown interest in the pay-per-use model for call centre software," Prem Uppaluru, president and CEO of Transera said in New Delhi.

The company, set up in April 2004, has pioneered a model where call centres can use Internet protocol networks to log on to its servers in US and use call centre applications.

Instead of buying software, the call centres can pay Transera on basis of number of employees or per minute of usage and avail additional capacity as and when needed.

Uppaluru said by using the model pioneered by it, call centres can bring down the costs of putting all infrastructure upfront and optimise their resources.

For developing the software, Transera has a team in US and India. In India, it has outsourced a part of the work to Mind Tree, which has a 15-member team working on Transera software.

Though the initial focus of the company was on Indian call centres serving the western markets, it is also looking at large domestic market.

"We will tie-up with an Indian system integrator who will host the call centre applications while for telecom connectivity we will tie-up with any large Indian player," he said.

The company has also tied up with NovaTel, which provides telecom connectivity to 18 of the 20 top call centres in India.  Transera has connected its servers to NovaTel networks which enable clients of NovaTel to use its applications easily.
