3CX Partner Training second (Advanced) Day

Today Stefan from 3CX talked about more details about how the SIP Protocol works and how 3CX is using it. He showed us how wireshark can be used to debug VoIP Calls, as i explained in my blog as well.

I learned that 3CX can tunnel RTP Packets and thus save bandwith, this is a feature that asterisk had before as well, which is now easily usable with 3CX.

I spoke about some details of berofix, for example how to analyze the ISDN Log Files with wireshark as well.

The main topic of my talk was about High Availability in telephony and how to implement it with the beroFos device. I also spoke about how berofix and berofos can be combined.
