Hi,
The attached scenario is entering some DTMF via RFC 2833 to navigate and
test an IVR.
Should enter 2 then 654321# followed by 1234# and then 5855551234#
What I see reach the server is 2, 65431# then 234 then 5855551234
Did I miss something? Is the SDP I have programmed in the initial INVITE
correct?
How reliable is SIPp in sending RTP packets, are enough being
dropped/skipped or lost that I don't see some of the DTMF digits reach the
server under test?
Version information:
[dknopp@dknopp-workstation workspace]$ sipp -v
SIPp v3.5.1-TLS-SCTP-PCAP-RTPSTREAM built Mar 8 2017, 16:46:11.
Thanks,
Dan
