IP-PBX is a private branch exchange (telephone
switching system within an enterprise) that switches calls between VoIP
(voice over Internet Protocol or IP)
Wigwag setup and configure complete PBX in
software, it is relatively inexpensive and easy to add additional
functionality, such as conferencing, Interactive voice response (IVR) and
many more… It runs on Linux and provides all of the features you would
expect from a PBX.
Benefits:
Easier to install & manage via web-based configuration
interface.
A software-based IP PBX is far less expensive than a
hardware-based PBX / PABX
Choose from the many SIP based hardware phones instead
of getting locked in with one vendor
