If your 3CX is hosted in the cloud, you need to have at least one so-called “router phone”

If your 3CX is hosted in the cloud, you need to have at least one so-called “router phone” or an SBC in the network on which the IP Phones are located. This router phone (or the SBC) will proxy all the voice traffic to your hosted 3CX and:

Encrypt all voice traffic for security
Combine all SIP (signaling) and RTP (media) VoIP Packets to overcome firewall and networking issues
Allow for local calls in the event of an internet failure
Save bandwidth by setting up internal calls between local phones directly.
A router phone can function as a normal phone but will also act as an SBC
One of the greates router phones currently available is the Fanvil V6x series
