Call Flow in Proxy Mode 

In proxy mode, every user agent takes use of proxy to relay its 
SIP message. Proxy may query a location database server 
about a SIP URL. Depending on the result, it may relay the 
request to a next-hop proxy, or send it to the destination peer. 
In this flow, Alice is located in atlanta.com. She is going to 
place a call to Bob, whose SIP URL is 

[email protected]

. Alice’s user 

agent passes the INVITE message to its proxy, atlanta.com. 
From the request URL in SIP message, Alice’s proxy
