java - JAIN SIP Unauthorized response -

i developing sip client using jain sip library in eclipse environment.

i having trouble getting authorization. have implemented md5 challenge , added authorization second register function.

the authorization credentials correct checked them available sip application. able register , make calls it.

this code initialization , registration

i compared both packets , didnt find difference. dont understand why not geeting authorized. localip , sipip different in case.

i think problem might ports didnt find on net assigning rport , sipport: 5060. more information on it.

the call ids on both registers cseq 1 , cseq 2 should same. different in case.
