If you provide your 3CX Server FQDN & Tunnel Password during purchase, we will install/configure the 3CX SBC service for a fully configured, drop-in, plug-n-play, SBC device.


The 3CX SBC is deployed to remote offices where there are more than 2 or 3 IP Phones, to direct only their signaling through the 3CX Tunnel and keep the media streams local which reduces the amount of internet bandwidth that local calls between phones use. SBC will bundle all SIP traffic over a single TCP port which simplifies your deployment by reducing firewall configuration. In addition 3CX SBC will add stability & security and allow you to easily manage and provision your IP Phones remotely.
