Thank you for letting me know they exist,
Sorry, that's a misunderstanding. They do exist but not in the format
you want. As I wrote, the .pcaps which come along with sipp contain DTMF
in RFC2833 (telephone-event) format, while you want audio-encoded ones.
Given the rest of what you wrote, you'll have to create your own pcap
files or modify the payload of some existing ones.

Hello! Thank you for responding. I'm referencing the ability to
generate an RTP stream from wav file (as I already have DTMF tones in
wav files).
If the pcap files for DTMF tones aready exist that would solve the
issue. Thank you for letting me know they exist, I was under the
impression I had to download/generated them on my own. :)
Alright I'll wait until 3.4 is ready for my distribution as my sys
admins would prefer I avoid compiling progress where possible.
Thank you again!
Robert,

Hello Robert,
I cannot see anything 3.4 - specific about DTMF tone support in the
3.4 manual.
What comes along also with the older versions of sipp is a set of pcap
files, each containing one DTMF digit in the form of ten packets in
RFC2833 format, which you can replay using pcapplay in your scenario.
If you need the DTMF in audio form in PCMA or PCMU for your test case,
that's a different story, here 3.4 gives you a possibility to generate
an RTP stream from a wav file in addition to the previously available
possibility to replay a pcap.
In such case, you'll need to use an audio editor (such as Audacity
which includes a DTMF generation function and supports both PCMA and
PCMU encoding) or your own script to create the audio file (mono, 8
kHz, PCMA or PCMU encoding depending on your test case) with the
required DTMF digits or the whole sequence. Now you have two options -
to roll out sipp 3.4 in your environment, or to convert the audio into
a pcap file using a script, or to rewrite the payload in an existing
pcap file using another (simpler) script. The pcap file format is
simple so it is not a big deal.
As for the rpm - packaging for different distributions is normally
done by that distributions' administrators. So if sipp 3.4 is not
available as rpm for your distribution, you can either compile it
yourself from sources or ask your distribution administrator for
handling that. In general, doing it yourself requires more of your
time and effort but you get the result faster.

Hello!
I'm trying to play a DTMF tone via sipp and it looks like it's
supported in version 3.4, but I can't seem to download that version
via yum. Is 3.4 avaliable via RPM or how do people get it?
Alternatively, is there a way to turn DTMF tones (wav) into pcaps for
playing in a scenrio file?
Thank you in advance,
Robert
