Fanvil A710 for 3CX SBC
The Fanvil A710 is a small, dedicated session border controller (SBC) that connects the phones at a branch office, store, or remote site to your 3CX phone system in the cloud. It does the job of a 3CX SBC without needing a spare PC or Raspberry Pi in the comms cupboard.

What the A710 does
When your 3CX system is hosted in the cloud, the phones at each site need a secure way to reach it through the local router and firewall. The A710 sits on the site’s network, creates that connection back to 3CX, and passes calls for every phone behind it.
You manage it from the 3CX phone system admin console, the same place you manage your extensions. Phones at the site are provisioned through the A710, so there is no need to configure each handset by hand or open a range of ports on the firewall.
