The best VoIP phone system for small businesses

We had a customer that had 3 different companies within the walls of the building. We were able to configure each company separately so that their rules, hours, and each had different SIP providers that needed to be configured up properly. Each had their own digital assistant and the system setup took only a few hours to complete with all the complexity that was involved. Technical support was outstanding in assisting with the troubleshooting and setup.

Pros

The 8 concurrent call Standard License is free to all companies. This makes it a perfect solution for churches, small businesses, and as the small businesses grow into medium sized businesses, the annual cost for the license with higher concurrent calls is nominal. When companies switch from the POTS lines, they need to figure out a good solution for VoIP. 3cx is lower cost than RingCentral and 8x8 as well as many other competing VoIP softwares.

Cons

Putting in supported APAP adapters is great, but when a customer has a non supported adapter, it usually works, but doesn't play nicely with the software as far as configuring it easily.

Serves small businesses very well for free.

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.

Pros

• 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.

Cons

• 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.

Reasons for Switching to 3CX

Technical problems with the tool, where the company took the decision to discontinue with the tool and acquire another one.

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.

Best for Work From Home

We needed our staff to be able to call clients and donors safely when they are working from home and we don't want them to use their personal numbers so this was a great option

Pros

Cons

Have to automatically switch from available to away No way to turn off/log off Have to dial 1 before dialing out No voicemail

Effective Phone System For Small, Simple Offices

For under 50 extensions and without any special functionality, 3CX is a very user-friendly platform. However, for any project that requires any custom functionality, 3CX will simply not be able to offer help.

Pros

The 3CX installer on both Linux and Windows is incredibly easy to use and users can go from nothing to a fully-featured phone system in less than 20 minutes. Once installed, the user interface is very clean and straightforward. The 3CX Softphone that can be installed on Windows and mac computers pairs effortlessly with 3CX provisioning files.

Cons

3CX offers very little customization outside of the user interface, and commonly phone system managers will be simply unable to perform more-complex call routing. As an example, dynamic outbound routes are simply not possible outside of the overly-simple Outbound Routes tab, and you are limited to only prefix, length of destination, and from extension. Compared to FreePBX and FusionPBX, the ability to customize 3CX is almost non-existent. 3CX Support will 100% of the time deflect any technical issues to the carrier, and after numerous ticket responses later, they will finally admit to being able to help. SIP SRV records are completely broken and not compliant with the SIP RFC. It's hilarious how catastrophic this lack of functionality is. Faxing is completely broken. It will be a complete nightmare if you attempt to run T.38 faxing over a 3CX phone system.
