Hi,
I'm trying to test the following scenario:
UAC (192.168.1.24) --->>> Asterisk (192.168.1.19) -->>> UAS (192.168.1.23)
UAS is started with -rtp_echo
UAC is started with uac_pcap.xml from sipp docs, playing g711a.pcap from
sipp.
In asterisk i just have a extension that call UAS. The problem is that UAC
send RTP packets but all with bad checksum, so they are discarded when they
arrive in linux machine.
I'm using ubuntu 16.04 and sipp 3.3-pcap, i've tried with other version
(3.2, 3.1) and i got the same thing, packets are received by the linux and
are not being delivered to asterisk. I can't see the packets with "rtp set
debug on" on asterisk.
With sipp 3.5 and 3.6-dev from git i've got segmentation fault when try to
send audio. send_packet.c send to failed with error: Invalid argument.
If i start the UAS with a scenario that play some pcap file, the packets
are received by linux correctly and they are sent to UAC.
If i start the UAC directly to UAS, same thing happens, the packets are
received by linux but not delivered to UAS, it shows "0 Total echo RTP
packets 1st stream", with wireshark i can see the packets, but all marked
with bad checksum.
As i said, i have tried with different version of sipp and different
machines, but same thing.
Any idea? Am i doing something wrong?
Thanks

Paulo.
