Hi Surya,

As the NOTIFY is an in-dialog request (for the dialog created by the SUBSCRIBE request), it will be routed by OpenSIPS to the SIP contact advertised in th SUBSCRIBER request - does the SIP URI in the Contact header advertise the TCP transport protocol ?

Hi,


I am testing opensips presence server 1.8.3 using sipp. I am using TCP as
the transport. When I send SUBSCRIBE, 200 OK is received fine but the NOTIFY
is sent on UDP.

When testing from 2 SIP clients it works fine on TCP. Is there something
special to take care while testing TCP from SIPP?

Below is the command and scenario file.
*./sipp 192.168.192.131 -t t1 -sf sn.xml -m 1 -i 192.168.192.128*
-------------------------------------------------
<?xml version="1.0" encoding="ISO-8859-1" ?>
<scenario name="subscribe">
   <send start_rtd="1">
</send>

   <recv response="200">
   </recv>

   <recv request="NOTIFY" rtd="1">
   </recv>

    <send crlf="true">
</send>

</scenario>
-------------------------------------------------

I am not able to figure out what the problem is. I suspect it is something
to do with sipp but not sure.
I couldn't find anything on internet, hence, posting here.

Thanks,
Surya
