I have kamailio behind a TLS termination proxy so the sockets are correctly
deduced to be TCP. However the clients only talk TLS to the proxy and are
confused when the top Via header added by Kamailio is TCP. Is there a way
for Kamailio to forcibly pretend its protocol is TLS? Like
advertised_address but "advertised_protocol" instead.
(With pjsip testing: it has a flag use_tls which ignores TCP from Kamailio
and continues to use the persistent TLS transport to proxy. Linphone fails
because it tries to honor TCP in Via and is unable to establish TCP
transport).
BTW I am using t_relay_to_tcp so Kamailio will return traffic to the proxy
as TCP even though the contact addresses specify transport=TLS.

Config works fine with mysql as topos backend. So the bug is restricted
to topos-redis.
Hi,
We’re still using kamailio 4.4 but we’ll be migrating to 5.0 soon.
Cool so it will be fixed when we migrate !
Thanks,
Andreas

Hi,
which version are you using?
A similar case had been reported some months ago and it should be fixed in 5.0.

Hello,
We have a use case where we suspend a transaction in a failure_route to give UEs that might be woken by a push notification more time to REGISTER and join the INVITE.
We’d like to drop the previous branches in this case. I tried using t_drop_replies() but it has no effect.
The doc states that t_drop_replies() is only working if a new branch is added. And from my understanding t_suspend() adds a new branch.
But is it possible that t_drop_replies() cannot be used with t_suspend()? Or am I missing something?
Kind Regards,
Andreas

When receiving an INVITE over a specific LTE carrier, I'm seeing 'c=IN IP4
192.0.0.4' in SDP, which isn't technically a RFC1918 or RFC6598 IP address
and thus nat_uac_test(8) fails.
What elegant workaround can be done to catch such specific cases?
Thanks.
Hello,
I'm using RTPproxy for the first time in bridged mode and I can't get kamailio/rtpproxy to rewrite the c parameter to the correct public ip address of kamailio.
The setup is as following:
Carrier ------[fiber]------ Kamailio ---------[lan]--------- Freeswitch
Kamailio is listening on two interfaces:
1) Private: 172.0.0.1
2) Public: 192.168.0.1 (since we have a dedicated fiber with our carrier, this is its public address)
Freeswitch is listening on:
1) 172.0.0.2
Carrier is on:
1) 10.0.0.1
I've started an rtpproxy instance on the Kamailio box using:
rtpproxy -s udp:127.0.0.1:7721 -u rtpproxy rtpproxy -p /var/run/rtpproxy/rtpproxy.pid -l 192.168.0.1 172.0.0.1
I've played around with rtpproxy_manage() and the various flags (ie, ei), but I can't get kamailio to set the correct public IP when the 200 OK has to be sent back to the carrier.
It always sets it to its private address, instead of its public address.
I'm using Kamailio 4.2 with sippy/rtpproxy 2.0.
Could someone please point me into the right direction?
Thanks!

Hi,
With Asterisk, we are able to get some peer round-trip connection statistic by setting qualify=yes for the specified peer.
It sends periodic OPTIONS to the peer and calculates the time round trip time.
It's something like - "Status: OK (30 ms)".
Is there any way to achieve this in Kamailio by using nathelper module, or any other?
Thank you.
Hi kamailios,
i have a creepy situation with v5.2.1 stable Kamilio. After a day or
so, Kamailio stop to process incoming SIP traffic via TCP. The
incoming TCP network packages get TCP-ACK from the OS (Debian 9,
4.18.0-15-generic-Linux) but Kamailio does not show any processing for
the SIP-Traffic incoming via TCP. No logs, nothing. While traffic via
UDP is working just totally fine.
When i look via command "netstat -ntp" is see, that the Recv-Q get
bigger and bigger. e.g.:
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program
name tcp 4566 0 172.17.217.12:5060 xxx.xxx.xxx.xxx:57252 ESTABLISHED
31347/kamailio
After Kamailio restart, all is working fine again for a day. We have
maybe 10-20 devices online via TCP and low call volume (1-2 call per
minute). The only settings for tcp we have is "tcp_delayed_ack=no"
How to could we debug this situation? Again, no error, no warings in
the log. Just nothing.

Dear friends,
I am working on a program on Kamailio and rtpengine proxy. I am wondering whether can I set Kamailio and rtpengine daemon on different physical machines. For example, I set Kamailio on a machine with IP address:10.109.247.80, and launch rtpengine daemon on another machine with interface parameter as 10.109.247.90 and ng port 7723. I set parameter in Kamailio.cfg with modparam(“rtpengine”, “rtpengine_sock”, “udp:10.109.247.90:7723”).
Unfortunately I got debug message like this:
ERROR: rtpengine [rtpengine.c:1710]: send_rtpp_command(): can't send command to a RTP proxy
ERROR: rtpengine [rtpengine.c:1746]: send_rtpp_command(): proxy <udp:10.109.247.90:7723> does not respond, disable it
ERROR: rtpengine [rtpengine.c:1616]: rtpp_test(): proxy did not respond to ping
And, I also tried to set Kamailio and rtpengine daemon in a same machine,and use modparam(“rtpengine”, “rtpengine_sock”, “udp:localhost:7723”). And Kamailio can work functionally under this situation. rtpengine daemon can receive ping message from Kamailio and rtpengine daemon can work as suspected. So for the later case, is it supposed that Kamailio be in the same machine with same localhost address? Otherwise, what’s the reason for my ERROR?

I need to send re-invite after pacemaker fails over on new rtpengine
server. Because new rtpengine dont participate in DTLS handshake and i hear
nothing, but silence. I think, may me its would be work. Do you have any
idea on this issue?
