What the QA folks in my group do is set an environment variable in a script to
the output of a command, then set a SIPP variable by passing it in with the
syntax '-key sippvariable1 shellvariable1'. In the scenario, they reference
[sippvariable1].
Roughly they would have something like:
Shell script:
#!/bin/sh
domain=$(cat domain.txt)
sipp .... -sf register.xml -key domain $domain ...
XML Scenario:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<scenario name="Example">
<!-- This scenario expects the following variables to be defined:
domain
--!>
<!-- REGISTER -->
<send retrans="500">
<![CDATA[
REGISTER sip:[domain] SIP/2.0
...
]]>
</send>
...
Hopefully that's useful.

Thanks Cheng Kun for the idea of using an external command, following on from
that thought.
if I run the following command in bash I get the RFC 1133 format I require for
the Date: header
date -d "+12 months" +"%a, %d %b %Y 00:00:01 GMT"
Although the SIPp documentation shows how to echo the contents of a varaible to
a text file it does not show how to set a new variable equal to the output of a
external command, can SIPp do such a thing?
Thanks

In this example it searches in Contact header and assigns value to variable 2,
then sends ACK by judging the 2's value.
But can you modify the date and timestamp?

<idkpmil...@sip2serve.com<mailto:idkpmil...@sip2serve.com>>:
Hi,
I am currently using SIPp 3.4.1 and I trying to emulate a UAS which uses the
Date: and Timestamp: header in its messaging. Is there a way to populate this
header with an internal variable/keyword that will be populated by SIPp when
the scenario is run?
If not can you consider adding support for date and timestamp header?
Example header format below:
Date: Mon, 22 Sep 2014 04:00:49 GMT
Timestamp: 1411358460
Thanks
Paul
