This is possible with my DTMF patch. See

Subject: [Sipp-users] Play PCAP file depending on values from injection file

Hi,

I'm trying to send DTMF digits using RTP according to a CSV injection file,
but I don't understand how to get it right. First, I tried this:

<nop>
<action>
<exec play_pcap_audio="/usr/share/sipp/pcap/dtmf_2833_[field4].pcap"/>
</action>
</nop>

But SIPp claims it cannot find the file
"/usr/share/sipp/pcap/dtmf_2833_[field4].pcap", because it did not expand
[field4] from the injection file. I read some thread on sipp-users from 2007
that said that you should assign the value to a variable first, like this:

<nop>
<action>
<assignstr assign_to="2" value="[field4]" /> <exec
play_pcap_audio="/usr/share/sipp/pcap/dtmf_2833_$2.pcap"/>
</action>
</nop>

But that didn't work either, since $2 was not expanded to the value of
[field4] in pcap_play_audio.

Is there any way to do this? I have a working scenario that uses SIP INFO
and reads DTMF digits from an injection file, and I also have a working
scenario with a hard-coded pcap_play_audio sequence. But I would like the
pcap_play_audio sequence to be determined by the injection file, just like
in my SIP INFO scenario, and I cannot figure out how to do that.

I'm using SIPp 3.1.9 (from the EPEL repo) on CentOS 5.

Regards
Ingemar
