I have been working as a VoIP telecom tester for nearly 5 years and have experienced many telecom systems such as Nortel, Genband, Avaya, Ericsson. I'm familar with ISUP, H.248, SIP and other protocols which are used in telecom. Especially, I'm very good at verifying SIP protocol by using SIPP and many other SIP tools. If you need a tester to verify your systems by your own tool, I can be fit to that work since I have skill of studying new tools and enquiry new knowledge. I have experience in working with people around the world such as people in USA, Canada, China, India and Turkey. I can guarantee that the work will be done in a specified time window and effectively. Moreover, you pay less for the better work.

All of the above without former instruction and those were my ideas to improve security and leave tedious work of copying and pasting information to an Excel spreadsheet. I was in charge of the platform security giving and configuring all the security policies for each equipment in the platform, I wrote the manual for doing this, so anyone could do it after.
