Es el mejor sistema de gestión de llamadas que he conocido
Revisado el 21/8/2021
Generalmente lo uso para hablar con clientes, proveedores y con muchos de mis contactos de trabajo y pues se ha vuelto una herramienta totalmente fundamental
Puntos a favor
Dentro la empresa que trabajo 3CX siempre ha sido la herramienta de trabajo principal para los agentes, además, los mandos medios atendemos nuestras llamadas con él y realmente me parece muy fácil de usar, precisamente es lo mejor de todo.
Desventajas
No le encuentro ningún contra aunque me gustaría poder modificar mi tono, recibo muchas llamadas al día y a veces me resulta un poco molesto.

Al principio como toda aplicación es complicada en lo que te acostumbras, el ingresar a cada usuario con su sesión fue algo complicado pero una vez que sabes como iniciar el programa , el como marcar , como redirigir las llamadas y hasta como agrupar las ext. , solo es cosa de familiarizarte con la aplicación 3cx
Puntos a favor
La aplicación es muy amigable para la tarea diaria de hacer llamadas y comunicarnos dentro del trabajo y fuera de el con los clientes, de igual forma la comunicación para redirigir las llamadas y comunicarnos es efectiva y mayor aun si contamos con las diademas para una mejor calidad de audio a la hora de realizarlas
Desventajas
La aplicación como tal es buena , solo tenemos que asegurar que tengamos un buen Internet para que podamos escuchar con claridad las llamadas , yo siento que la aplicación es muy buena y no tiene contras por el momento

Revisado el 29/9/2022
Se mejoró la comunicación interna dentro de la empresa ya que al poder instalarla en los celulares te puedes comunicar en todas partes, además del ahorro económico que está App genera
Puntos a favor
Es una herramienta fácil de usar, muy practica ya que se puede utilizar tanto en computadora como en celulares lo cual ayuda a mejor la comunicación en todas partes, tiene mensajes de voz que llegan al correo que tienes programado para escucharlos de manera clara, además que ahorras dinero ya que no necesitas estar con alguna compañía para su funcionamiento
Desventajas
El único contra es que si se te va el internet las llamadas no entran a la aplicación

As a VoIP service provider we have tried them all
Revisado el 1/4/2018
Reliable phone system
Puntos a favor
3CX is very feature rich that is constantly improving every day. The top pro is its rock solid reliability. VoIP is rather mature at this point but its not without its problems - particularly network based problems. 3CX successfully eliminates these with the use of a border session controller.
Desventajas
Support can be very expensive if not purchased through the proper channel partner. Company refuses to heed directional input and new "ideas", they have their path defined. As far as VoIP is concerned these cons can really be said about any PBX, so don't take these as 3CX specific. You wont find anything better than 3CX - trust me we have spent a lot of resources trying.

Serves small businesses very well for free.
Revisado el 18/1/2020
In my opinion, it is a very good tool and hardly ever had problems, because the tool is very stable and with a very good usability, serving very well small businesses.
Puntos a favor
• It is free.
• Assists in the company's internal communication.
• It is always updated with improvements.
• Ease of receiving and transferring calls.
• Ease of configuration and installation by the end user.
Desventajas
• We used the trial version quietly for 1 year, but due to technical problems due to a codec, it caused a major internal problem where we stayed 3 days without a phone. For this reason the support of the company that provides the service asked us to change the application.
Respuesta de 3CX Traducir a Español
We are sorry to hear that you had codec issues. Can you explain which codec was used and what issues it created?
Codecs work using the SIP Offer - Answer model - a standard in SIP used for the update of session dialogs. This means that when a codec is offered by one endpoint (phone), and the receiving endpoint answers "no available codec" then a codec exchange occurs where both endpoints try to find one common codec (language) to use for their media. Like this every call is serviced and has more chances to get 2 way audio. It is important to tell us which codec you tried to use. Because firstly, we might have an issue to investigate or we might also give you an alternative codec you can use. We support all major codecs so I am surprised how the company that serves you recommended that you change the whole app.
Nonetheless, thank you for your feedback. I will forward this to the development team.

3CX Soft Phone
Revisado el 6/4/2020
This is a great piece of software when working from home. I connect to my VPN and I am able to make and receive international calls from the comfort of my home office.
Puntos a favor
Great for making international calls, from any location. I use this on my laptop and connect a bluetooth headset.
Desventajas
When I am using a bluetooth headset and listening to something (e.g music), if I start the 3CX app up it changes the way sounds comes out the headset. So each need to keep the app close and open it each time i want to make a call. A bit annoying.
Respuesta de 3CX Traducir a Español
Thank you for your comments about our software! About the issue you faced with the headset, our software does not directly affect the headsets, rather it registers to the sound devices the OS is using. Having said this, I would suggest checking the OS sound settings, and also maybe try another headset if you have one available, maybe a wired one to rule out this being somehow related to BT.

3CX - The Softphone that works
Revisado el 10/1/2020
The day to day operation is more streamlined and at a management level, it helps keep track of those taking calls on out various teams. It also allows us to be away from our offices but take the mobile app with us and get our VM's via email... all positives and allows us to be more attentive.
Puntos a favor
3CX has made it easier to maintain our calling network and allows us to bring its features outside of the office which aids in our day to day. The phone dial pad it self is very user friendly and the software it self has a very ease of use feel to it.
As a manager it is nice to view, listen and transfer my teams calls on the fly - the logging system also allows me to keep track of activity within my teams.
Desventajas
Not a ton of cons to be honest, there are some issues of delays from when you ask for a function (click delay) like looking up a contact from the address book and clicking to call the contact, sometimes there is a bit of a delay.
The product could use a bit of a refresh look, but overall the ease of use and user friendly Softphone does hit it's marks.

Call me.......The best phone system
Revisado el 7/11/2022
The transfer (number port) from our old company was extremely smooth and hassle free, the business wasn't impacted at all.
Puntos a favor
The phone system appears to be reliable, and the new handsets we had installed, are very easy to use, with features such as touch screen and one button voicemail (no typing in a sequence of numbers) The display is large, and you can automatically see who is "speaking" as their name appears in red on the screen. The touch screen display can show in excess of 25 extensions numbers at a touch, no more entering extension numbers.I am also really pleased with the reports I can generate, such as the calls each employee has taken in a day, all sent via email at a time specified by you, and so easy to set up.The administration features, such as setting bank holidays, Christmas day is so much more user friendly than my old system.So far, I am very impressed, there are features I haven't even explored yet.
Desventajas
One major issue we found was, you cannot rewind the voicemail by seconds, you can only skip to the beginning. We have very large orders left on the voicemails, and we need to be able to jump back to hear one product. You can log on via your PC, however for us this isn't the best option.We have added a ticket and hope the feature can be included.

I definitely enjoy working and managing 3CX. It makes managing and monitoring my calls in a busy modern workplace a breeze!

Getting in Touch with Fellow Colleagues and Clients
Revisado el 30/5/2021
3CX is used on both phones and pc which means a user can have it on the move or in a specific working area. The software has a lot features in one place that assist in communication.
Puntos a favor
The software is good with organizations. I use it in the organization making outbound and taking inbound calls from both clients and colleagues. 3CX also has features like call transfers and call conferencing enables a link between different parties.
Desventajas
As any other software there are some issues. The system crashes sometimes and communication is cut affecting the organization. The system cannot work with just any kind of internet connection the software will not work properly.

3CX - The most complete IPPBX on the market today
Revisado el 11/12/2019
It just works all the time. Windows or Linux (Debian) both versions whether in the cloud or on hardware are solid, solid, solid.
Puntos a favor
When an IPPBX is able to run off of an Intel NUC and provide full call center functionality, CRM integration, soft client via WebRTC mobile client with ZTP integration with the leading IP phones and be set up literally in 10 minutes ... not sure how you can beat this !
Desventajas
It has more to deal with their partner levels and it constantly changing along with the support they provide to resellers when quotas are not hit that has become a concern. Communication for license renewal has gone directly to end users instead of the reseller of record that has soured the community.

3CX Phone for Windows - EndUser review
Revisado el 19/9/2018
This system is pretty reliable from my end user perspective. The voice mails come to my inbox quickly which is nice. I would recommend this to anyone with a business of the size where I work, we have around 80 employees.
Puntos a favor
3CX is easy to operate for me as I am an end user. I receive calls that are transferred to me and I rarely get any complaints that the call didn't make it to me or was dropped in the process. It is also easy to transfer calls to other people or call out by just typing the first couple of letters in the person's name. I can choose their extension or their cell phone if they are listed in our directory.
Desventajas
I have to restart the software from time to time because it will stop working. I also have some issues with the log of incoming and outgoing calls. I would like to be able to call someone right back if they just called and I don't have their phone number. Some calls are remembered and some are not, it seems random. I can see the number as it comes in but if I need to call that person back sometimes their number doesn't remain in the log, I do not know why.

3CX Review
Revisado el 3/6/2021
Overall, if you are looking for an extremely intuitive, inexpensive phone system solution 3CX is what you need. Their support is top-notch and the phone system itself is very easy to manage.
Puntos a favor
What I like most about 3CX is the ease of use. The interface is extremely intuitive and very user-friendly. Also, the install instructions are extremely easy and I was able to set up a virtual Debian server and install 3CX in under 30 minutes.
Desventajas
I wish 3CX offered time-based routing. It would be nice if you could designate the calls to go to certain places during certain times rather than having it strictly during hours and after hours. There are workaround for this, but it would be extremely convenient if it was built into the interface.

3CX Phone System - Kinetix, Platinum 3CX Partner
Revisado el 6/5/2016
Puntos a favor
Feature/Functionality matches up to any competitive solution.The fact that you have "Standard" or "Professional" as your purchasing options makes the decision simple. And, when you choose one or the other, there are no other "Ala Carte" options. You get what you get. No "extras" that end up being tacked on at the end of the sales cycle. The 3CX Phone System system simply works. The "hybrid" capabilities between Analog, SIP and PRI/MPLS are a great way to introduce either redundancy, least cost call routing and to provide for future changes/expansion/growth.
Buy what you need for the next few years. You do not want to limit yourself to what you need today, then need to upgrade the license count within a year or two. The upgrade path would suggest purchasing the upgrade up front will cost much less. For example, a 16SC License can be purchased today, and to upgrade later to a 32SC License will cost the initial purchase of the 16SC License, AND 80% of the 32SC License.
Desventajas
Would be great to see the ability to break office hours down beyond single days. For example, we have clients that have standing meetings on Monday from 11:00a to 12:00p.

Easy to use, no hassle PBX system with enterprise reliability and small-business ease of use.
Revisado el 8/3/2018
Puntos a favor
First off, this software successfully allows for administrators to set up multiple incoming SIP trunks from one provider. Predecessors such as Trixbox and Asterix had trouble implementing this feature without extensive customization. If you are looking for multiple trunks, this is the software for you.
Other options are the usual fare for a PBX - it's essentially everything users have come to expect from Trixbox or Asterix or other FreePBX software. The beauty is in the execution, though, as it takes almost no time to set up a system using this software.
Desventajas
Base licensing does not include some of the more advanced features that would set this apart from other software options. The need to pay for more trunks feels like a natural pay-gate, especially considering how much this feature is requested in DIY PBX communities.

All in one place!
Revisado el 5/12/2019
All in all a great program to utilize features that phones have. Other switchboards in the past that I have used had very little functionality and not the useful features that 3CX has.
Puntos a favor
-Everything about your phone communication is in one place. You can do web meetings, check your voicemail, see who all is on the phone or away at lunch. You can organize your day with your coworkers.
-It's on apps that you can put on your phone if you can be at your desk or if you can't take 20 minutes trying to figure out how to forward your calls to your cell on the phone itself.
Desventajas
-You have to know what clicking on certain things mean. In other words, don't accidentally click on a coworker's box if you do not mean to call them. I have been there a few times.

Adaptable and Progresive
Revisado el 8/10/2018
I have managed 3CX for my company for over 6 years. During that time we have gone from hosting the PBX on Windows to Hosting on a Digital Ocean Linux VM. 3CX is much more stable on Linux. With a variety of hosting options, you should be able to fit 3CX to your environment and wallet size. Even having an always on backup server is an inexpensive, but necessary endeavor that will keep your employees and clients happy. 3CX is a very competitive option, with many PBX providers that I have queried not even wanting to attempt to compete against the 3CX PBX.
