VoIP can be a practical, modern solution to replace your current PBX system. VoIP is the general term for the transmission of voice communications over the Internet.
By using the IP instead of traditional phone dial tone, VoIP often offers a significant cost savings over normal long distance and international rates, and provides a host of features not available with traditional telephone services.
Features of VoIP include voicemail to email, where voicemails are emailed to you as a .wav audio file, allowing you to access them from a mobile device or computer, and unified messaging and “find-follow”, which lets you instruct your phone to ring another number (such as a mobile phone) if you do not answer your desk phone. VoIP phone systems also include auto-attendant, ring groups and hunt groups, and allow for a variety of call routing configurations.
