title: Difference between sip proxy and sip outbound proxy
body: <p>I'm little bit confused about sip proxy and sip outbound proxy? What is the basic difference between sip proxy and sip outbound proxy? Is it mandatory to use sip outbound proxy along with sip proxy? Can anyone point me out from the below image which one is the sip proxy and outbound proxy?</p>
