Outsourcing makes sense to many companies for a whole host of reasons.

For short term projects it is not always financially viable to employ an individual or individual(s) to do the project so you could end up with excess overheads that you cannot afford. 

Outbound telesales is one of the most popular resources to outsource, because of the short term needs of a business for a project like this.

Many call centres have specialist office furniture for their large numbers of staff to operate from. Office desks, which are more like booths than normal office desks, come in some cases with fitted panels that contain plug sockets and power points. 

Most of these types of office furniture items are designed specifically to fit as many people together in a uniformed fashion with their office desks in close proximity to each other and paneled partitions between your co-workers office desks to keep the noise levels low.

Of course, sometimes there is a need to outsource work abroad such as banking or IT services and in these cases you could be speaking to a person at an office desk across the other side of the world that is contributing to your businesses success!
