Background: We have been successfully running a 3CX voip pbx at our company for a few years. 30 end points, mainly polycom 501, 430, 331 phones. Our phone system and all end points use a completely separate network from our data network. The phone network connects to the internet using a dedicated T1. The only traffic on this line is from the phone network. The 3CX server and all phones use internet IP addresses. For now, no firewall exists. Ultimately we'd like a firewall in place and then provide the end-points (phones) with internal (NAT) IP addresses, but we were never able to get the system working with a firewall introduced into the mix. (Introducing a firewall could be a second project) The point for now, however, is that no firewall exists to mask the root of the problems that we're having.

Currently we are using a hosted VOIP solution but have outgrown it. Our primary goal is to transition to our own asterisk/FreePBX (or other) server, either hosted internally, or with a VPS or dedicated server in a data center. We would like to use SIP trunking and have been researching providers that provide per minute charges as opposed to "line" charges. The implementation should take into account proper security, QOS, call capacity, and basic functionality Voicemail Multiple calls support Switching between active calls Call conference Call transfer (blind, attended), hold Speaker, mute Call history logs faxing DHCP/Auto-provisioning Since this is a coworking space with long and short term clients, one of the main goals of the project will be to implement a billing system where we can charge for long distance calling and have the proper logs, report, invoices.
