-=== I saw PJSIP sends multiple REGISTER requests, one unregistration and one registration. Why? === #reg02
+=== PJSIP prints "IP address change detected" then immediately sends unregistration. Why? === #regipchange
 
 This feature is part of NAT traversal feature of PJSUA-LIB. It works by comparing the Contact URI that we use in the REGISTER request against the address and port that the server returns to us in the 200/OK response of REGISTER request. If the addresses are different, PJSUA-LIB would reconstruct a new Contact URI based on this address info, unregister the existing Contact, and simultaneously send a new registration with the new Contact URI.
