I am proud to announce the first beta of our new 3CX Voice Application Designer product. Proud because this is an industry first – 3CX Phone System is the first PBX to have such a powerful graphical voice application building tool. With 3CX Voice Application Designer you can create voice applications that automate time intensive business processes with a few mouse clicks. For example, create a voice application that queries the caller for a customer number, then validates this number against a database and routes the call based on customer type.

Whilst 3CX includes a good number of supported VoIP providers, it is impossible for us to template all the VoIP providers out there and to test them.  If you have a VoIP provider you would like to use with 3CX that is not included, you can perform your own tests to see if the VoIP provider can be used with 3CX. This article explains the tests that you need to perform to be sure that you can use the VoIP provider with 3CX. If the tests are succesfull, you can send the completed test back to the 3CX Support Team for templating and it will be included as a Community Tested VoIP provider VOIP Provider Information As a first step collect the basic information of the VoIP provider and its supported features VoIP Provider name: Telephone number assigned: Authentication ID: Authentication Password: SIP Server/Registrar + port: Outbound proxy + port: Registration Time: Max Simultaneous call: Supported codecs: DID number support: Inbound Tests Has the account registered and re-registered fine without any errors or unusual logging in the Server Status? YES / NO After having left the account idle for 24 hours are you able to make an inbound and outbound call through it? YES / NO When making an inbound call, terminate this as soon as the INVITE appears in the Server status. Does the VOIP provider line indicator in the Line Status revert to Green

If you are using a VOIP provider , then you will have to configure your firewall correctly in order to get reliable results. Your firewall must support STATIC PORT MAPPING. 3CX Phone System needs the following ports mapped on the router or firewall to operate properly: Port 5060 (TCP and UDP) – Used for SIP protocol transmission – must be a static mapping, no port translation Port 5090 (TCP) – Used for 3CX tunnel (if tunnel is enabled) Port 9000-9015 (UDP) – Used for RTP protocol for incoming and outgoing calls For business grade results you will also need a static/dedicated IP. Note that many cheap routers do not correctly port forward, and this will lead to problems when making calls

Ta’ Xbiex 14 April 2009 – 3CX has published a case study which outlines the process of Allcare’s transition from a traditional hardware PABX to a software based solution provided by 3CX. 3CX is an international manufacturer of software-based IP PBX developed specifically for Microsoft Windows and based on the SIP standard. As a premier insurance service provider, Allcare operates an inhouse call centre dealing with around 2000 daily calls. 3CX Phone System for Windows consists of the server software, soft phones or SIP hardware phones, and a VOIP Gateway to connect existing phone lines. A VOIP provider can be used to leverage low cost calls across your user network. The system can use the existing computer wiring (and share the network point with the computer) and can be installed on an existing, non-dedicated Windows server or run as a virtual machine.

Connecting to a Fax to print to Fax from a Windows XP Computer The scope of this article is to be able to send faxes to a shared printer. This shared printer can be any printer – hardware and software. However in relation to 3CX Phone System, the shared printer in this case would eventually be a computer/server with the 3CX Fax Sending module installed. The 3CX Fax Sending module will be shared and users in the network will be able to connect to it and send faxes through it using Microsoft Fax. Add Printer Wizard Click start and go to Printers & Faxes, and select Add Printer. The Add printer wizard will launch.

System requirements for the clients: Windows Fax and Scan should be installed. Print Services should also be enabled. The Fax printer on the Server machine should be shared to network users. Network Users should be granted permission to be able to print on this Fax Printer. To install the client: Click on Start, Programs and click on ‘Windows Fax and Scan’.
