<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As a result, the SIP UPDATE is being sent but since the original From Tag is not being used (i.e. and a new tag is generated), the SIP client (sipML5) does not recognize it as part of the existing dialogue. Attach is a pcap of the test
made.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Subsequently, I’ve also tried to recover the from using uac_restore_from() function but got the following an error message.<o:p></o:p></p>
