Hi,
this is the my first topic.
Now i have a problem. I have created a scenario of Session SIP on IMS
network.
I have installed OpenIMS on four virtual machine:
* P-CSCF: 192.168.10.92
* I-CSCF:192.168.10.91
* S-CSCF: 192.168.10.93
* HSS:192.168.10.90
The realm is snodo.
The REGISTER scenario runs correctly. After bob and alice register on
IMS network, i launch the Session scenario (uac.xml):
<?xml version="1.0" encoding="ISO-8859-1" ?>
<scenario name="Session Alice - Bob - Client Side">
<send retrans="500">

with the command:
sipp -sf uac.xml 192.168.10.92:4060 -i 192.168.16.49 -p 5060 -m 100
The IP of Client is 192.168.16.49 and the IP of Server (uas) is
192.168.10.80. On 192.168.10.80 i have launched the uas scenario.
The sipp result is:

sipp: There were more errors, enable -trace_err to log them.
All INVITE messages result Unexpected Message.
So I have used Wireshark to sniff the session and the error of INVITE
messages are:
User Datagram Protocol, Src Port: sip (5060), Dst Port: 4060 (4060)
Checksum: 0x9e45 [incorrect, should be 0x749a (maybe caused by "UDP
checksum offload"?)]
Bad Checksum: True
I don't understand what is the problem. Have you a idea?
Thanks
Davide
P.S. Excuse me, my english is very poor.
