HI all,

I am trying to achieve the following:

UACUAS
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:

[snip]
   <recv response="100"
        optional="true">
  </recv>
  <recv response="180" optional="true">
  </recv>

Hi Divin,

The problem is that your 100 and your 180 are both marked as optional="true". SIPp doesn't allow a send to happen immediately after an optional="true", because it's not clear what should happen - it can't wait for the message before sending (as it's optional). If it should send it immediately, you can put it before the 100 and 180 - if it should send it after it gets the 180, you could remove the optional="true" from the 180. It may be possible to add a pause after the optional 100 and 180, and send the UPDATE after the pause, but I'm not sure whether that would work.

Hope that helps,
Rob
