Virtual PBX phone systems can function just like a big corporate phone system. All standard calling features including call transfer, caller ID, voicemail, call forwarding, call distribution to multiple extensions, and other features are integrated into them.

They can attend all incoming calls automatically and efficiently distribute them to the right locations. The auto attendant incorporated in the small business phone systems greets callers with appropriate welcoming messages, and routes the calls to live staff members, or if unavailable, to voice mail. The auto attendant can receive multiple calls simultaneously and route the calls to several departments or individual employee lines. Unattended calls are diverted to alternate numbers.
