What is a virtual PBX and how does it work?
A virtual PBX is an advanced telephony system hosted entirely in the cloud that allows companies to manage their calls without the need for physical equipment or cables. Unlike older systems, it works as a smart software in charge of receiving, diverting and optimizing all your communications, ensuring that each client receives the attention they deserve from automatically and professionally.
IP Telephony: VoIP and WebRTC technology
Thanks to technology WebRTC we eliminate the need to install complex applications; you can enjoy unlimited extensions and talk in HD quality from the browser on your computer or mobile phone wherever you are
Advantages of the virtual PBX in the cloud
In 2026, the cloud stopped being an option and became a necessity. By taking the leap you can instantly expand your device and add extensions, and receive and make calls from home, the office or on the road with your company number.
Differences with the traditional switchboard
The main difference is the freedom. The physical switchboard ties you to a place and requires expensive installation, while the virtual one from Fonvirtual It is flexible and digitall, without cables or breakdowns, with AI and data analysis included.
Where can I receive communications from my virtual PBX?

Local Telephone Numbers
Carry your company number or hire a new one. Have a presence throughout Spain by adding numbers from different provinces to your virtual PBX.

Through other channels

What are the functionalities of a virtual PBX for companies?
IVR recordings
Personalize your switchboard with your own voiceovers.
Discover more
The voiceovers are informative messages that the person calling you will hear, guiding them about which company they are calling, if they are doing so outside of business hours or simply to guide them through the different options that we offer in our company. A complete configuration will always have at least four voiceovers:
Welcome
An opening statement informing the caller about the company they are calling («You have contacted Gestoría Pepe and friends»). Depending on the configuration we want, it is possible that this voiceover needs to continue, guiding between the different alternatives in a menu of options («If you want to talk to accounting, press 1. To administration, press 2»)
Busy
Secondly, it is always interesting to include a message informing us that our lines are busy, leaving the caller the opportunity to leave a message or try again after a few minutes.
Out of hours
For those calls that occur outside of our business hours, it is advisable to include the time when they can find us («Our opening hours are from 7 in the morning to 3 in the afternoon and from 5 to 8 in the afternoon») in addition to giving the possibility of leaving a message in our mailbox so that we can contact the client later.
Holidays
Finally, for vacation or holiday periods, a specific announcement is recommended in which the caller is informed when they can call again («Due to a local holiday, our business will remain closed until the 8th»)
By default, in fonvirtual we will configure all these voiceovers in TTS (text to speech), that is, in synthetic or robotic voice. Customers with Premium modalities onwards will be able to include their own fully personalized voiceovers, recorded with a natural voice, with us in charge of uploading them to the switchboard configuration.
Options menu
Distribute your calls between different departments
Discover more
One of the most useful features of the virtual PBX is the options menu, because it allows us to divide the calls we receive between the different departments, making it more comfortable for the caller and more efficient for our company (“If you want to talk to accounting, press 1, Administration, press»)
The caller will only have to press the key corresponding to the option that best fits the reason for their call. Thanks to the options menu, in most cases we will ensure that the person who answers the call is the most suitable.
There are many segmentation possibilities for these calls. We can do it by department, subject or even language. For example, «For Spanish press 1, English, press 2”)or by zonesFor customers from Madrid, press 1).
In addition to how useful the options menu can be, it helps build an image of a great company.
Call recording
Store the calls you receive and make
Discover more
Call recording will allow you to access a wealth of information about conversations contained in calls that would otherwise be lost. It is especially useful for those cases in which it is necessary to rescue the exact content of certain conversations.
By default, access to the recordings will have a limited period – 10 days – until the recordings disappear from your profile, so we will need to download them periodically if we want to rescue them all. You can expand access to recordings by purchasing an additional FTP service.
For more information about call recording or their legality, you can send it to the address info@fonvirtual.com
Schedules
Discover more
Business hours
The main configuration should work coinciding with our work schedule. For example, from Monday to Friday from 9 in the morning to 2 in the afternoon and from 4 in the afternoon to 7. Within these ranges, our calls will come in completely normally and will be answered according to our ideal configuration.
Outside business hours
A second niche could be known as «out of hours«, that is, all those hours that are outside of our previously defined business hours (Monday to Friday) and on Saturdays and Sundays as a whole. When we receive calls within these hours, a voiceover may sound informing us of the hours of operation along with a voicemail to leave messages.
Holidays
For those days when due to a national or local holiday or simply due to some type of peculiarity that prevents us from answering calls, it would be advisable to create a specific configuration for those days. For example, on October 12, so the caller will hear a statement such as «Due to the holiday of October 12, our offices will remain closed throughout the day today.s».
Vacation
Finally, if our entire company closes during a specific holiday period, it would be interesting to inform customers who call us. For example, «From August 15 to 31, our company will be closed for holidays»
Statistics
Analyze your call statistics and metrics to improve your business.
Discover more
All clients will have access with their password and username to the fonvirtual platform, where they will be able to enjoy various reports on call statistics.
This is not a simple list of calls received; Our platform allows you to apply a large number of filters that will allow you to create different reports depending on the information you want to collect. You will be able to obtain reports that include periods of hours, days or months, depending on the duration of the calls, from which origins they were made…
The possibilities are so many that you will quickly see that the statistics tool provides a large amount of information about how you manage your calls, helping you improve.
For example, if we have a menu of options in our configuration, you will be able to have statistics on which option is the most clicked by our callers, who answers those calls the fastest, or which department misses the most calls.
Virtual numbers
Given the versatility of virtual numbers, statistics are very useful for launching advertising campaigns or knowing the success of our new offices where we have placed a new contact number. For more information on this aspect, we recommend that you visit our section virtual number
Call transfers
Discover more
When any of our extensions receives a call, the virtual PBX allows the call to be transferred to another extension without having to disconnect the call. In addition, the transferred line will be free again to continue receiving calls. The fonvirtual virtual PBX offers two types of transfer:
Transfer attended:
Upon receiving the call, the person answering it will be able to communicate in parallel with another extension to see if it can answer the call, while the caller is kept on hold with music. The idea is that the extension making the transfer consults in advance with the other if it wants to accept the transfer, if it is interested or any other eventuality. Depending on your response, the call will eventually be transferred to the new extension or the first extension will pick up the call with the customer.
Unattended transfer:
This type of transfer directs the call directly to another extension, without any type of consultation.
For more information about call transfers, you can contact us at infousa@fonvirtual.com or expand it with our video about call transfers.
waiting queues
Discover more
The waiting queue is very useful for those companies in which several calls are received simultaneously and the caller takes a few extra seconds to be answered. To prevent you from hanging up, your call is placed in a waiting queue with music where it will wait until one of our extensions ends the call it was answering and is released.
It must be considered that callers will not remain in the queue forever; However, it is true that it will help us save some time to answer the call, in addition to creating an exclusive image of our business.
Show your main number
Make outbound calls from your extensions showing your landline number.
Discover more
One of the most differentiating features that fonvirtual offers is being able to propagate the header landline number when calling from any of the extensions. That is, whether we call from our WebRTC lines, from our mobile phone or from any other landline that we have as an extension, we can always show the person we call the same number. It’s what we call make outgoing calls.
Propagating your number is very useful in building loyalty among our customers and suppliers; They will always have a single contact number to call us back, which is exactly the number we want them to know: our switchboard. You yourself can specify which extensions are enabled.
At this point, it is worth specifying that outgoing calls are made differently depending on whether they are made from fonvirtual’s WebRTC lines or if they are made from your landlines and mobile lines.
