And then there's everybody's favorite the "butt dial message." You see a missed call from that person and the voicemail icon. You think to yourself, "wow if they called me and left a message it must be important." Utter disappointment and frustration sink in when there is nothing but silence on the message.
Businesses, however, may prefer the security of a local system. They have the option of purchasing a private branch exchange (PBX) server to handle all their calls from local hardware.

It’s a good practice for each of your team members to have their own personal business phone numbers. There are many reasons why they shouldn’t use their personal cell phone number for business, so you’ll want to give them their own phone number through your VoIP provider or phone system.
These business phone systems support more than just a large network for inbound and outbound calls. Most of these systems are VoIP-based phone systems with cloud hosting options. This enables a more affordable and scalable solution that supports collaboration between employees. This collaboration can also be done through several applications. It also provides you and your employees with the capacity to work outside of the office.
