(January 2016, Under construction)

Description of Requirements

Here is a mini example to set up a telephone service that provides these features:

• Public telephone number offering two IVR options... (IVR is where you hear a recorded message which gives you options to press 1 for this, 2 for that, etc.)
  1. Option no. 1, to a VoIP Phone
  2. Option no. 2, redirect to a PSTN line during working hours and Voicemail at other times

We can represent this example as a simple flow chart:

Overview of configuration

We'll need three numbers for this example, let's assume our numbers are as follows:

1. 123001, the main number that customers call. This will play the pre-recorded message and offer calles to press 1 or 2.
2. 123002, the number that is used for the VoIP phone. Pressing 1 on the main number will call this number.
3. 123003, the number that is used to redirect to an external number or go to voicemail. Pressing 2 on the main number will call this number.
