HI all,

I am trying to achieve the following:

UAC UAS
Invite -->
<--- TRYING
<--- 180/183
Update --->
<-- 200 OK for UPDATE
<--- 200 OK for INVITE
ACK ---->

SIPP doesn't even execute this. Am I missing something obvious? If I move the 
UPDATE to below the 200OK (INVITE), it works.


My script:

<scenario name="Basic Sipstone UAC">
  <!-- In client mode (sipp placing calls), the Call-ID MUST be         -->
  <!-- generated by sipp. To do so, use [call_id] keyword.                -->
  <send retrans="500">
