Using PortaBilling web interface administrators can quickly and conveniently define how users access IVR applications by dialing phone numbers. Your customers would dial a phone number from the PSTN network or their IP phone to access a specific IVR application.
For example, *98 for voicemail, 12125551234 to access the prepaid calling card IVR, or *123 to access the audio conferencing facility. So when PortaSIP receives a call, it matches the destination number with one of the access numbers and then launches the specific IVR application associated with that access number.
An IVR application can contain one or several entry points (access numbers). Using the PortaBilling web interface, administrators can type in or paste the list of access numbers.
The administrator can customize the properties of the IVR application. The access numbers assigned to it inherit the given IVR application settings.
