Hello,
I have a problem today, It's strange for me.
Suppose we have this senario:
uac1------->SEMS(mo profile)------->Kamailio-------->SEMS(mt
profile)---------->uac2
In above topology, we have two interfaces(intern,extern) for SEMS, and
just used as SBC (sbc application).
if i used port=5060 as external port, every things is right and log
file is like this:
[#7fed3f9f9700/32820] [run, udp_trsp.cpp:352] DEBUG: vv M [|] u recvd

Why my public ip address is there here? I just changed external
port=4080 in sems server. In SDP protocol i have the same problem when
i changed external ip port in sems server.
Thanks.

Why my public ip address is there here? I just changed external
port=4080 in sems server. In SDP protocol i have the same problem when
i changed external ip port in sems server.
is this message log the one of the first SEMS (mo profile) which is
sent by uac1? In that case it's the uac1 which puts the 172.1.1.125 IP
addresses in the SIP message. Or rather: I can imagine that there's a
SIP ALG on the NAT between the uac1 and SEMS, which only changes
packets when the destination port is 5060.
Stefan
Thanks.

Hello,
Yes. The log is for sems with mo profile.
I used SEMS as sbc applications in my network. Let me paste my
configurations below:
#sems.conf

sip_ip_intern=192.168.18.20
sip_port_intern=5060

#sig_sock_opts_extern=force_via_address
tcp_connect_timeout_extern=1000
tcp_idle_timeout_extern=900000
I was forced to disable "sig_sock_opts_extern" option,
#sbc.conf is like this:
profiles=refuse_with_200,register,mo,mt,refuse
active_profile=$M($m=>methodmap),$M($si=>src_ipmap),refuse

header_filter=blacklist
#header_list=P-App-Param,P-App-Name,P-Route,Remote-Party-ID
header_list=P-Route,Remote-Party-ID,P-Source-IP,P-Source-Port
I think it is big challenge if i am dependent to NAT between the uac
and SEMS (SIP ALG) when i changed default port on sbc.
How can i solved this problem in this regards?
Thanks. With Regards.Mojtaba

Hello,
if nobody here can provide an hit, maybe you should report the issue to
the sems project:
- https://github.com/sems-server/sems/issues
Cheers,
