OUR HAPPY CLIENTS
WHAT OUR CLIENTS SAY ABOUT TELECONTRAN !!
The whole context of the course, specially RTP, VOIP Security sections are very much interesting.
The training handbook is the best and I especially like the SBC portion, like SBC function, SBC Configuration, softswitch function etc.
The training is very much informative and it offers very good overview of roaming that covers both commercial and technical aspects.
The course helped me to learn different call flow scenarios, roaming architectures, LBO, roaming services etc. in details.
