Dear All,
I am trying to handle 180/183 receive as optional and send PRACK with
following,
Works for 3.1 version but not in 3.2 version.
Got "<recv> before <send> sequence without a mandatory message. Please
remove one 'optional=true' (element 6).." as there is no mandatory receive
before PRACK.
<send retrans="2500">

</send>
<recv response="100" optional="true"> </recv>
<recv response="180" optional="true" next="2"> </recv>
<recv response="183" optional="true" next="2"> </recv>
<!-- Sending PRACK irrespective of 100rel in provisional response -->
<label id="2"/>
<send>
<![CDATA[
PRACK sip:[remote_ip]:5060 SIP/2.0

Shivakumar Balur
