Traditionally, the offshore outsourcing sector pushes the growth of the industry. But increasingly, servicing the domestic market is also proving to be a strong driver for growth.

'In the Philippines for example, 78 percent of the industry services the local market and 34 percent provide international service. The outsourcing sector appears to drive growth in innovation and technology adoption, and this is again led by the Philippines,' says Catriona Wallace, president of callcentres.net.

The demand is still strong for the contact center industry, and the pressure is on to sustain the growth. Other areas like South America and Europe are increasingly becoming aware of the opportunities in this sector, and they are increasingly becoming the Asia-Pacific region's competitors.
