(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
2. 123002, the number that is used for the VoIP phone
3. 123003, the number that is used to redirect to an external number or go to voicemail
