    I am a Computer Science Engineer and I have been working in VoiP industry for more than 7 years now. This has been and still it is like the dream job for me. To like the job you do means to be devoted on doing it and to have responsibility. My biggest objective has been learning telephony to the core and I have worked mostly with SIP/SIP-T protocol. There are many technologies and software that can accomplish VoIP communication and I have worked with some of them such as Kamailio, Opensips, Asterisk, Freeswitch, etc. To sustain the proper functionality of these softwares I have also learned a lot of MySQL and Linux administration, which helped me doing my job. I love my job and it makes me feel great every time I accomplish a new project. less
