Many large corporations are using outsourced staff to take or confirm orders over the phone. And in recent years, there has been a large shift away from Indian call centres to the Philippines. One of the reasons is the level of proficiency that Filipinos have over the English language. They are taught in English during school and University, and have a large influence of western culture from the US.
If you need to expand your telephone sales or receptionist staff, without the cost of employing someone full-time, then outsourcing maybe the answer for you.
