title: Can't register with SIP account (opensips server)
body: <p>I am trying to build an Android application that uses linphone to make calls, using OpenSips for SIP registration.</p>
  
  <p>I've successfully installed OpenSIPs in Ubuntu server,and created account in it, but can't register with this account. Got <code>(Registration on sip:xx.xx.xx.xx failed:timeout)</code></p>
  
  <p>I'm a complete beginner in SIP and opensips,so I can't figure out what i'm doing wrong!</p>
  
  <p>Any help would be appreciated,</p>
  
  <p>Best regards,</p>
