Computer telephony, sometimes simply referred to as CTI, is the use of computers in telephone call management. The term is often used in describing computerized services of call centers, such as user support or telephone sales. It is also sometimes used to describe the ability to use your personal computer to initiate and manage phone calls, which was the main focus of this paper. Zoiper softphone was installed on two different laptops. Using the SIP2SIP sip provider, three accounts were created which were used along with the softphone to initiate calls from one computer to the other. Call information was fetched directly from the sip provider web site, where it was stored separately for each accounts incoming and outgoing calls. The data was acquired in three steps: downloading the website source code, parsing the source code, saving parsed call logs in the database. Each step is performed by a different script. All the scripts were written using python 2.7 for Windows 7 64-bit version. Calls are stored up to three weeks on the sip provider web page, so it is necesary to save them in the database. We used a sql database created with MySQL Workbench 6.3 DBMS.
