 Hi.

 

  

 

 When a Proxy Server, in a Domain A, needs the address of some user 

 registered in another Domain, let say Domain B, such Proxy send a 

 request to a SIP Redirect Server. Then, such SIP Redirect Server sends 

 useful information to the Proxy, so that this one can finally send 

 message to a Proxy Server in Domain B. In this way, the user 

 registered in Domain B will be contacted.

 

  

 

 My basic questions are:

 

  

 

 1)      How can the first Proxy Server know the SIP Redirect Server's

 address?

 

 2)      Does the SIP Redirect Server always know the address of the target

 Proxy Server in Domain B? If yes, why it is possible? When and who 

 does populate data into the SIP Redirect Server?

 

 3)      If the SIP Redirect Sever doesn't know the target Proxy Server's

 address, in Domain B, what is the Proxy Server that is the destination 

 to the first Proxy Server's messages??

 

  

 

 Thanks in advance.
