We continue from the Set up Asterisk Server on Ubuntu VM in VirtualBox to test Linphone : Part 1, and will show how to configure Asterisk and Linphone as SIP client on two devices to call each other over WiFi.
Step 1: Establish IP connection between the SIP client (Linphone) and the Asterisk server
First let’s put the ubuntu virtual machine on the same IP subnet as your mobile device. Assume that your mobile device running Linphone is on wifi at home. The simplest way to establish IP connection between the virtual machine and your mobile device is to put the virtual machine to be on the same subnet.
To do so, assume the machine the VirtualBox is running on is already on the same WiFi network as your phone. To check, you can check the IP address of your phone and then check that of your VirtualBox host. The first three octets of both IP addresses should match. For example, my iPhone’s IP is 192.168.1.103 and my macbook air hosting VirtualBox has IP of 192.168.1.105. The first three octets are “192.168.1″. To test, you can “ping” your phone from your host machine. Say from my macbook air, to ping my phone, I would run the following command from a terminal| | | Next → |
