Info: 2 day course

When: in curand

Where: Bucharest, Romania

Course Overview:
In this course, you will discover the explosive dynamics of bringing voice and data together on a single network. You will learn How SIP Phone has evolved; review the typology, architecture, SIP, SDP and RTP protocols including different implementations.

The course participants will setup IP Phone and register to a Softswitch, define different services and applications which are widely used by SMB and large Enterprise.

Each one of the participants will access sophisticated Softswitch which will be on the same network for generating end-to-end IP telephony and Video calls. Using the Wireshark each participant will experience the usage of the Wireshark to analyse the various protocols.

Basic knowledge of:
– IP Networks
– Basic telephony
