"From seats of less than 1,000 in 2000, there are now more than 15,000 seats," Domingo said.
He said the government expects the number of seats to increase to 30,000 by the end of the year.
From an initial investment of P565.53 million in 2002 which generated employment for 6,560 workers, investments in contact centers have grown sharply by 181.16 percent as of April this year.
The highest recorded investment inflow in contact centers was recorded in 2001 at P2.467 billion, creating jobs for 10,426 workers.
In 2002, however, there was a slight drop in contact center investments to only P1.59 billion. But the figure still generated jobs for 11,003 workers.
For the first four months of the year, investments in contact centers have already exceeded the 2002 level at P1.897 billion.
According to the BOI, there are about 37 foreign and Filipino firms servicing known Fortune 500 companies.
Some of the major contact centers in the country are AOL, Convergys, Sykes, eTelecare, People Support, Cybercity Teleservices, Ambergris, InfoNXX, Vocative and C-cubed.
"The preference for Filipino call centers are attributed to the Filipino’s affinity for the US culture," Domingo said.
Filipinos are also highly proficient in the English language.
