Every worker in every office today owns a PC on the table always on a network (LAN or internet). But every worker in an office does not have an office phone. This is because it is very expensive to setup office telephones in every office. This expenditure is not only in terms of finance but in hardware and maintenance too. This expenditure is usually too high for most medium and low income businesses in my country. On the other hand, connecting an office PC to a network (LAN or internet) is an obligation in today's hi tech world and is not even too expensive to do.

Office Com SIP takes this advantage to develop a solution capable of doing real time calls, SMS, voice mails and file transfers at a very low cost. This system is VOIP based just like Skype but has an external USB Hard Phone and during operation, it does not interfere with the PC's multimedia hardware so you can still play music or even do a Skype call simultaneously.
