Review of 3CX IP PBX VoIP Phone System for Windows
What is VoIP?
VoIP, or Voice over Internet Protocol, refers collectively to a set of technologies that allow for voice conversations to be transmitted via the Internet.
What is a PBX?
A PBX, or Private Branch eXchange, is a device - with or without software - that allows a business entity to easily configure and manage a block of phone numbers. Many medium to large businesses use PBXes for employee phones, over the PSTN (public switched telephone network).
What is an IP PBX?
An IP PBX is simply a PBX designed to work over the Internet. With some IP PBXes, everything is software based. Others have hardware components that allow for integration with the PSTN.
Why VoIP and IP PBXes?
VoIP and IP PBXes allow businesses to have advanced communications features at lower rates than with regular PSTN based technology. Part of the reason for lowered costs is a single set of wiring (your computer network), and the other is software based features. Additionally, if you’re using SIP-based IP PBXes and equipment, you have a wide array of equipment to choose from, instead of being bound to proprietary hardware of typical PSTN-based PBX makers.
What are 3CX’s Features?
Depending on your viewpoint, 3CX’s MS-Windows-based IP PBX phone system’s most important feature is that it is based on the SIP (Session Initiation Protocol) VoIP standard. Besides making it thus compatible with other SIP VoIP systems software and hardware, phone numbers need not change when an employee has to move offices.
The 3CX system offers a VoIP Gateway, which allows it to be integrated with PSTN phone lines. So you can have a hybrid setup where internal calls are over VoIP and calls to and from outside the office are over PSTN.
Summary
3CX offers a fully integrated business grade VoIP solution with their partner netVortex. If you’re not yet ready to take a full plunge into enterprise IP PBXes, you can download a copy of their free edition, which includes a SIP server. This package works on Windows 2000, 2003, XP, Vista, and offers voice mail, call transfer and other features - all supported at their 3CX forums. You wil need a proper SIP-based phone.

NOT READY FOR PRIME-TIME!
Over the last few weeks I have testing the free 3CX SIP server, largely due to the favorable review here, and I have to say, that while it is feature rich, easy to use and even in it’s three not-so-free incarnation very affordable, it has one insurmountable flaw: Unstable Registration!
After days of having been unaware of any outages - 3CX does not have any means by which it could alert to them - I found, by studying the logs, that the PBX goes off-line for 10 minutes at a time, virtually every time there is a registration time out or momentary loss of connectivity.
While, according to developers and staff at 3CX, a retry escalation, beginning in second increments, is supposed to kick in, the test PBX reacted exclusively with 10-minute timeouts, before retry.
Lengthy attempts at trying to solve the problem, using 3CX’ support forum, yielded little to no usable info. Developer and users alike simply repeated their mantra of ‘opening port 5060′ and ‘try to register a soft-phone’. Any and all attempts to get the issue resolved at the company-level were meet only with attempts to sell the software, including a support agreement - not at all encouraging.
At this time I cannot recommend the 3CX SIP server and suggest to those interested in operating an IP PBX to stay with the Linux-/Asterisk-based flavors, which are as much infinitely more complex as they are infinetly more reliable.

I have tried 3CX Phone System too, and it worked just great for me. Installed it in 30 minutes max - Spent more time reading the manual than installing it, ran it with Grandstream phones and softphones such as SJ Labs and Xlite and had no registration issues at all.
Got my sub-6 year old kids to hammer away at playing phone games with each other - Child’s play.
Have been using it ever since even via remote extensions over the Internet.

Paul Said - you sound suspiciously a lot like a competitor of 3cx who is unhappy with the extensive feature set of the free edition!
I have used 3CX Phone System reliable in several installations already, and i found it much easier to use then a linux based solution

I tried 3CX and was somewhat underwhelmed - not very intuitive and missing strong IVR capabilities. Check out CallButler http://www.codeplex.com/callbutler. It is a Windows-based open source PBX that has some really impressive IVR tools, intuitive interface and better audio quality than 3CX…plus, it’s free!

C’est un bon petit téléphone voip, parce que tous les autres téléphones libre sip ne comprennent pas les transfert d’appel, qui est une nécessité dans toute société. Également le support des micro-casques Plantronics.
et plus d’inforamtion sur ce softphone voila un article que j’ai déjà écris sur son utilisation et ces avantages.

unlike Asterisk, 3CX is not open source… just like allez MSW related products, you can apprciate the meal but you have no way to know how to cook it .. all the difference is here .. so i am still prefering ”the complexity” of asteris.
