15. SMS PROTOTYPING Bit tricky!!! November  8,  2010   MODS  2010  |  uday  m.  shankar  |  @udayms  |  acrossthinlines.com   15  
16. DISCLAIMER: THIS IS NOT THE ONLY WAY TO DO THIS!!! Refer back to this PPT online later… November  8,  2010   MODS  2010  |  uday  m.  shankar  |  @udayms  |  acrossthinlines.com   16  
17. You need November  8,  2010   MODS  2010  |  uday  m.  shankar  |  @udayms  |  acrossthinlines.com   17   NOWSMS Gateway Windows Server SMS Gateway Server Mobile Phone GSM Modem Capability PHP + MySQL
18. This is how it looks November  8,  2010   MODS  2010  |  uday  m.  shankar  |  @udayms  |  acrossthinlines.com   18  
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 November  8,  2010   MODS  2010  |  uday  m.  shankar  |  @udayms  |  acrossthinlines.com   19  
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 November  8,  2010   MODS  2010  |  uday  m.  shankar  |  @udayms  |  acrossthinlines.com   20  
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.

22. VOICE PROTOTYPING Even more tricky!!! November  8,  2010   MODS  2010  |  uday  m.  shankar  |  @udayms  |  acrossthinlines.com   22  
23. You need November  8,  2010   MODS  2010  |  uday  m.  shankar  |  @udayms  |  acrossthinlines.com   23   Windows Server Skype PrettyMay Call Center PHP + MySQL Skype International Number Prettymay.net
24. This is how it looks November  8,  2010   MODS  2010  |  uday  m.  shankar  |  @udayms  |  acrossthinlines.com   24  
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. November  8,  2010   MODS  2010  |  uday  m.  shankar  |  @udayms  |  acrossthinlines.com   25  
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!
