3CX is starting to publish a series of short technical VoIP videos which we have called VoIP Nuggets. These are bite size 3 to 10 minute snippets or ‘nuggets’ with technical information about 3CX Phone System for Windows /ISDN telefooncentrale which we trust that you will find interesting and useful.

The first one is a high level overview of SIP Call setup and the ports involved.

Let us know what you think!
