Rafael S.

I have over seven years of experience in the VoIP telephony industry. During this time, I have held various technical roles where I’ve had the chance to learn and develop. My hard work and dedication have paid off, and now I hold the role of a telephony engineer in a leading company in the telephony field. I have successfully completed many technical projects such as: - building telephony VoIP systems from scratch in the retail and wholesale businesses - setting up interconnections to over 200 carriers all over the world - upgrading systems and configurations and several other projects. The technologies I have worked with are: LINUX, KAMAILIO, OPENSIPS, ASTERISK, FREESWITCH, MySQL, GRANDSTREAM, AUDIOCODES, SANGOMA. I have a very good knowledge of SIP, SS7, RFC3261, etc... I am motivated by success. Therefore I employ my dedication and skills to ensure that every undertaken project is completed successfully. Thank you for the opportunity! Rafael
