SIP/VoIP Client for Raspberry Pi

SIP/VoIP Client for Raspberry Pi
From the point of first contact to completion, Khaled was very professional and prompt with replies. Upon completion of my request, Khaled provided the complete code required, plus a full written guide on how to complete my project. Having no coding experience myself, I had been trying to debug the code for over 2 weeks. Khaled had the complete code, de-bugged, and working back with me in under 1 hour. I would recommend Khaled to anyone needing coding assistance.
