[Sipp-users] Segfault when using next and ontimeout options in a recv message

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hi folks,

I'm using SIPp 3.1 and have run into an issue with the script I have at
the moment, basically I have a scenario where I can receive multiple
invites so I have set up a basic loop. We recv the first reinvite and
then send 200 Ok and process the ack and then if there is another invite
I want to go back to send the 200 Ok and process the ACk otherwise I
want to continue.

This was done as follows (snippet from scenario).

  <recv request="INVITE" rrs="true" timeout="5000">

  </recv>

   <label id="1" /> 

   <pause milliseconds="100"/>

   <send retrans="500" timeout="5000">

    <![CDATA[

      SIP/2.0 200 OK

      [last_Via:]

      [last_Record-Route:]

      [last_From:]

      [last_To:]

      [last_Call-ID:]

      [last_CSeq:]

      Server: SIPp client/[sipp_version]

      Contact:
<sip:[field0]@[local_ip]:[local_port];transport=[transport]>

      Max-Forwards: 70

      Content-Type: application/sdp

      Content-Length: [len]

SDP blah

    ]]>

  </send>

  <recv request="ACK" optional="false" crlf="true" rrs="true"
timeout="2000">

  </recv>

  <recv request="INVITE" rrs="true" optional="true" next="1"
timeout="5000" ontimeout="2">

  </recv>

  <label id="2" />

Continue.. blah

Now the problem is that if I have next and ontimeout in the recv then I
get the stack dump as shown below.

Do you have any suggestions? Is there a better way to do this or have I
just found a bug?
