One of the biggest advantages of using a virtual extension is that employees can work from any location, yet still stay part of the same phone system. This means that a user can take advantage of all of the calling features that a specific VoIP service offers like voicemail, custom greetings, etc. through the use of a softphone on a mobile device. However, you should be aware that most virtual extensions only offer free inbound calling, unlike regular extensions that can offer unlimited inbound and outbound calling.
Also, having virtual extensions as part of your company helps to keep everyone within the same system, regardless of their location. This is helpful for employees who have home offices or are constantly on the go. Also, it keeps employees for having to use the same voicemail box or the same phone number for both their professional and personal lives. With a virtual extension, employees can receive work-related calls on their mobile devices, even though they are being called on a separate number.
