19. Setting it up - Mobile
• Nokia phones do not work here
• Use a Sony Ericsson or Samsung
• I recommend Sony Ericsson K750i
• Connect the phone to PC by USB
• Setup the mobile phone to work with your PC
in GSM Modem mode
• Install all drivers and back up data
• Clear your inbox

20. Setting it up - PC
• Install PHP/MySQL stack on your PC
• Download and install NowSMS on your PC
- www.nowsms.com
• Create these tables in your MySQL
– incoming
– outgoing
– keywords
– responses
• Test your PHP from browser - phpinfo();
• Test PHP from command line

21. How all this works
• NowSMS intercepts all incoming SMS messages
and fires a command in the CLI (command line
interface).
• It then takes the output of the command and
uses that as the output to reply to the number
from which the sms originally came from.
• NowSMS passes incoming message to the
command as arguments.
• Now… We do our magic in PHP/MySQL and
ensure that we print out what should be sent
out.

25. Setting it up - Skype
• Install Skype client on your PC.
• Or get a Skype international number and
configure your Skype on the PC to use the
international number.
• Install Skype on your mobile phone.
• Create two user ids in Skype – one for the test
candidate and one for the service provider.
• Install PrettyMay on the Windows server and
create `call-flows`.
• Create and use Audio Files as necessary.

26. How all this works
• When you make a call from Skype on mobile to
the Service Provider Id, it rings on the Windows
Server.
• The PrettyMay software running on the server
intercepts the call and plays audio files according
to the flow you have created.
• PrettyMay also listens to DTMF tones received
and plays different audio files.
• This makes your voice prototype pretty
interactive!
