title: Does SIP RFC allows multiple endpoints registered to one account?
body: <p>Sorry, if this is a repeated question.</p>
  
  <p>I am using FreeSwitch which uses Nokia Sofia SIP stack.
  It allows me to register multiple endpoints using one user credentials.
  e.g. I can log in using user id 1000 with multiple devices.</p>
  
  <p>I want to know whether SIP RFC 3261 allows multiple endpoints registered to one account or not?</p>
  
  <p>Update me about this.</p>
