It took some time, but today we finally uploaded a really good beta of 3CX Phone System V5. The reason it took so long is because we packed a lot of new functionality in there. We also made significant changes to our phone system in order to prepare for new features and scale even better.
3CX Phone System V5 adds 3CX bridges, allowing for easy connection of remote branch offices. It has a built in VPN to allow external extensions to connect with a minimum of firewall configuration. It features phone provisioning, call recording, an inbound fax server, sip forking, BLF (so that you can see busy status of other lines on the phone), SIP trunking and G729 codec support. Many other the hood features too, such as a fully configurable SIP templating system. Check out version 5 by going to our version 5 beta forum
