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
