Does it possible increase cSeq manually (for example remove and then
append headers?) for UAC module when send INVITE messages with Auth, or
kamailio have pseudovar for this header?
Hello.
I’m having some problems using websocket to communicate a webRTC client
with the SIP world.
I have a Kamailio with a websocket port running on 5062, from that socket
I’m receiving a SIP INVITE from a sipML5 client with 2531 bytes of length.
When I made the capture on the other leg (the pure SIP side) I only see a
SIP INVITE with 1500 bytes. Seems that something is fragmenting the packet
but not putting all the parts together. Could this be a problem with
Kamailio?. Does someone has the same problem?
Hope that someone could help me.
Best Regards,
Ricardo Martinez.-
Can somebody please tell me what would be a verified combination of kamailio and rtpproxy?I mean, for example, kamailio 4.1 and rtpproxy 1.x that can be downloaded from:http://<real_url>
I found at least 3 different places where one can download rtpproxy:
http://sourceforge.net/p/sippy/rtpproxy/ci/master/tree/https://github.com/miconda/rtpproxyhttps://github.com/sippy/rtpproxy
I downloaded the one from https://github.com/sippy/rtpproxy and have tested against kamailio 4.1, 4.2 and they are not compatible.It seems that the logi inside the function "send_rtpp_command" is not compatible with the rtpproxy version from https://github.com/sippy/rtpproxy and that causes kamailio to disable rtpproxy and it becomes useless.
Second questions: do the feature added to the rtpproxy (parameter -A to use external public IP for devices behind NAT) is compatible with OPENSIPS only?
I am about to test with kamailio 3.3, I will update this post later onthank you in advancejp
Dear All,
Greetings,
I want to implement kamailio server as failover and load balancing.
Is there any configuration needed in kamailio.cfg.
As I have searched in blogs, For load balancing, Virtual IP is added and
also heartbeat software is needed.
Please let me Know how to configure kamailio server for load balancing and
failover
Waiting for response
Thank you,
Regards,
Nandini
This is my setup:
UAC -> firewall (1:1 nat) -> Kamailio:5060 - > asterisk:5080
. |
. sip providers
I'm running kamailio 4.1.x & ast 11 based on aspitos kamailio configuration tutorial.
My problem is port number in via, contact and from headers is 5080 instead of 5060 for calls to provider. Public ip is fine. I have used advertised_port=5060 but no change. Also tried record_route_preset(ip:5060), but no change.
I can make calls but I would imagine I would miss acks & and reinvites.
Any thoughts on what I'm missing?

I seem to be going round in circles… I am trying to use dlg_bridge() from the dialog module to establish a call between two SIP endpoints. I have tested with Snom phones and linphone soft phone with the same result.
I get an outbound call to the first (from) end point, I answer the phone… and then nothing obvious happens.
I can get this same result when using kamcmd or from within the kamailio.cfg. For example using kamcmd:
kamcmd dlg.bridge_dlg sip:105@mykamailioip sip:106@mykamailioip sip:mykamailioip:5060
I expected this to send an invite from "controller" via my KamailioIP to my registered local subscriber 105 (from), and then send a re-invite to 105 so that 105 creates a call leg to 106 (to).
The kamailio.cfg is pretty much the default. I am running 4.2 and rtpengine to proxy the RTP streams.
Not sure if it is necessary or useful but I call setflag() at the start of the request_route() to set the Dialog flag. What else should I have included in the kamailio.cfg to make this work?
Also is there any way to control the SDP in the initial invite from dlg_bridge. By default I see RTP/AVP, with alaw and ulaw…. I’d like to offer RTP/SAVP swell or instead of RTP/AVP.
Thanks
Hello,
We have a setup where Kamailio 4.2 is used in front of Asterisk as WebRTC
Proxy doing the encryption and NAT Traversal.
Everything works as expected, except that BYE Requests sent by the WebRTC
Client are not forwarded by Kamailio to Asterisk. We use record routing.
Instead Kamailio responds with a "404 Not here".

I installed Kamailio 4.2 and the latest rtpproxy. When starting Kamailio I see these lines:

I run rtpproxy like this:
/usr/local/rtpproxy-install-dir/bin/rtpproxy -l <public ip here> -s udp:10.0.2.68:7722 -F -d DBUG:LOG_LOCAL3

loadmodule "rtpproxy.so"

modparam("rtpproxy", "rtpproxy_sock", "udp:10.0.2.68:7722")
I have tried with localhost, with 127.0.0.1 and get the same results ( I mean configure kamailio to contact rttpproxy with localhost instead of ip and at the same time running rtpproxy with the same reference.
I can see the rtpproxy running/listening

In the rtpproxy I see that it is sent data and it replies too, I even got a wireshark capture showing that as well:
Oct 27 21:54:41 ip-10-0-2-68 rtpproxy[3608]: DBUG:get_command: received command "3931_2 V"

But somehow kamailio does not see it:
[root@ip-10-0-2-68 sbin]# ./kamctl fifo nh_show_rtpp
which: no greadlink in (/sbin:/bin:/usr/sbin:/usr/bin:/)
which: no gdb in (/sbin:/bin:/usr/sbin:/usr/bin:/)
udp:10.0.2.68:7722:: set=0
index:: 0
disabled:: 1
weight:: 1
recheck_ticks:: 53253287
I even when to the kamailio code and saw something that may have something to do with it but havent tried it yet:, in the implementation of the function "send_rtpp_command" I see that the socket created is using TCP. But I tried configuring kamailio/rtpproxy to use tcp instead but I also got the same results, kamailio seems to fail to acknoledgwe the replies from rtpproxy.
I also have SELINUX disabled and the iptables are not running.
I dont know what else to check, if somebody can shed some light into this I'd appreciate it.
