  Hi,
  
  I would like to know what's the behaviour in case of OCS Federation.
  
  A company A with userA has a sip URI and a E164 phone number.
  A company B with userB has a sip URI and a E164 phone number.
  
  userA wants to call userB, not through its SIP URI but using its E164 phone number.
  
  IS OCS able to reverse look-up  userB  phone number in order to
  use Federation call through the Edge Servers or is the call automatically
  routed to PSTN ?
  
  Reformulated question :
  E164 phone number reverse look-up is processed by Front End for users
  in the same forest : is it the same for federated users ?
  
  
  Thank you !
