  Make outbound Google Voice calls.
  
  This patch allows for outbound Google Voice calls to be
  dialed from Asterisk using chan_gtalk. Below is an example
  dialstring.
  
  exten -> blah,1,Dial(Gtalk/asterisk/+15552225555@voice.google.com,,)
  
  In this example, 'asterisk' is the jabber.conf profile configured
  to connect to your gmail account. In order to receive Google Voice
  calls make sure to enable 'allowguest=yes' in gtalk.conf.
