Country: Australia
Company: funny enough, Dutch Digital Dynamics
Owned: Well by me

.
Offices: 3 remote sites one PBX all on same network segment (as I own the network infrastructure between the offices)
Employees: Depending on type of project can range from 3 up to 200+
Equipment:
Server: Dell PowerEdge (servicing multiple apps including 3CX)
Switch: Netgear smart switches
Routers: Billion, DLink (wired and wireless).
Network: Mixture of 8Mbs, 54Mbs, 100Mbs, 1000Mbs.
Phones: AT530, AT530P and HP 6965 (SIP and WiFi currently under review)
ATA: Lynksys (is there any other?

One pstn line, one DID line seem that is all we need as we do a lot of mobile phone traffic. We are investigating a GSM gateway posibility into 3CX.
Traffic type: VoIP, Video and Data
Traffic control: QoS, ToS.
Average phone calls: approx 20 ph (and increasing now i am spending some time with 3CX). Switching between PSTN and DID, not including Mobile.
There are several businesses here in AU currently in the process of implenting or building upon the 3CX software. Commercial confidentiality restricts me too name them.
If they are on the forum they can speek for them self.
If you looking for some references if this application is able to work in a real environment. Well we run everything through 3CX and we have not had any problems. So from my point of view the application is small business ready, enterprise will not be long from now but I would not recommend that as yet simply because i have not done a load test on the application so I cannot recommend what I do not know.
