Hi, sir,
We try to setup Mediaproxy on CentOS 6.6 with kamailio-4.2.1 SIP server. We
use Linphone android version as SIP client to test.
attached kamailio.cfg.txt is our kamailio-4.2.1 SIP server config file. pls
help to rename kamailio.cfg.txt to kamailio.cfg.
kamailio-4.2.1 SIP server is run on public IP server,and Linphone SIP
client is run behind NAT.
The problem is that only callee can hear caller's rtp audio data. caller
can not hear callee's audio data. And the call will auto disconnect after
about 30s time out.
Below's our modification regarding the kamailio.cfg file,pls help to check
if this is OK or not ?
#foxconn gallice add start
MediaProxy module
loadmodule mediaproxy.so
modparam(mediaproxy, disable, 0)
modparam(mediaproxy, ice_candidate, high-priority)
modparam(mediaproxy, mediaproxy_socket,
/var/run/mediaproxy/dispatcher.sock)
modparam(mediaproxy, mediaproxy_timeout, 500)
modparam(mediaproxy, signaling_ip_avp, $avp(nat_ip))
modparam(mediaproxy, media_relay_avp, $avp(media_relay))
#foxconn gallice add end
# account only INVITEs
if (is_method(INVITE)) {
setflag(FLT_ACC); # do accounting
use_media_proxy(); #foxconn gallice add
}
# Manage incoming replies
onreply_route[MANAGE_REPLY] {
xdbg(incoming reply\n);
if(status=~[12][0-9][0-9])
{ #foxconn gallice add
#route(NATMANAGE); #foxconn gallice delete
use_media_proxy(); #foxconn gallice add
} #foxconn gallice add
}
For mediaproxy,we can see the media related processes are already run.

The acc module does not post records anywhere, neither syslog nor db. The

Regarding the FROM header, the only change done is to add + to callerid
(after replacing 00 if present), this is extensively tested feature in past
6 months.
I have analyzed all the SIP packets in call using ngrep, they all seem
perfectly fine. All packets (request + reply) are correctly received and
forwarded by kamailio. Unfortunately i deleted them and need to get new

Hello,
you can try with latest git branch 4.2 and see the results.
At a quick look between the version you reported to work and the new
version you run, I couldn't spot a commit that could be the reason.
Do you get the acc record in syslog for INVITE?
How do you set the values for replacing From header? If you load from
database, be sure the values are valid. I see the uac module complains
about restoring operation. It might be the reason for the issues -- config
could be ok, but the subscriber data wrong.
You should save the traffic for a while and check the packets for missing
records -- you can use tools such as tcpdump, sipgrep, ngrep to store the
traffic in a file for later analysis. When you find a missing record,
search in the file with the sip traffic and see if something is broken
there.
Cheers,

Hi,
About 3 weeks ago i upgraded one of my production server with latest
stable kamailio version 4.2.1-fad00a. Now i am getting a lot of complaints
about missing CDR events in ACC table. I observe following problems,
1. There are only BYE records in acc table, no record for INVITE or ACK.
2. In kamailio logs when ACK is received against 200 OK response for
INVITE, i see following errors,
--

Of course all these errors are bogus, I have checked all headers in ACK
(not just FROM header), they all seem perfectly fine and valid.
3. Then the dialog times out,

4. Any further sequential requests complain about unable to find
