title: Asterisk multiple IP registration
body: <p>I have Linux box with several IP addresses running Asterisk.</p>
  
  <p>Is there a way to force asterisk to make trunk registrations from specific (not default) IP addresses? I need to connect 2 users from the same asterisk box to the same provider via different IPs.</p>
  
  <p>Thanks a lot in advance for your help.</p>
