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
