Now you can make outbound calls through the SIMCARD calling a telephone number with 9 as prefix. 10.We ll create an incoming route for the calls from any external number to our SIMCARD. We re going to use an IVR for incoming calls. Go to PBX => PBX Configuration => IVR. Click on Add IVR (Figure 4.11). Set the following: Name: Name of IVR (WelcomeIVR in this example) Announcement: Record which will be played for incoming calls.
