Kamailio and RTPProxy

I installed Kamailio 4.2 and the latest rtpproxy. When starting Kamailio I see these lines: Oct 27 21:54:26 ip-10-0-2-68 kamailio: DEBUG: <core> [sr_module.c:590]: load_module(): load_module: trying to load </usr/local Oct 27 21:54:26 ip-10-0-2-68 kamailio: DEBUG: <core> [sr_module.c:357]: register_module(): register PV from: rtpproxy Oct 27 21:54:26 ip-10-0-2-68 kamailio: DEBUG: <core> [cfg.lex:1724]: pp_define(): defining id: MOD_rtpproxy Oct 27 21:54:32 ip-10-0-2-68 ./… [View More]kamailio[3887]: ERROR: rtpproxy [rtpproxy.c:1707]: send_rtpp_command(): timeout waiting reply f Oct 27 21:54:32 ip-10-0-2-68 ./kamailio[3887]: ERROR: rtpproxy [rtpproxy.c:1716]: send_rtpp_command(): proxy <udp:10.0.2.68:77 Oct 27 21:54:32 ip-10-0-2-68 ./kamailio[3887]: WARNING: rtpproxy [rtpproxy.c:1573]: rtpp_test(): can't get version of the RTP Oct 27 21:54:32 ip-10-0-2-68 ./kamailio[3887]: WARNING: rtpproxy [rtpproxy.c:1610]: rtpp_test(): support for RTP proxy <udp:10 Oct 27 21:54:37 ip-10-0-2-68 ./kamailio[3898]: ERROR: rtpproxy [rtpproxy.c:1707]: send_rtpp_command(): timeout waiting reply f Oct 27 21:54:37 ip-10-0-2-68 ./kamailio[3898]: ERROR: rtpproxy [rtpproxy.c:1716]: send_rtpp_command(): proxy <udp:10.0.2.68:77 Oct 27 21:54:37 ip-10-0-2-68 ./kamailio[3898]: WARNING: rtpproxy [rtpproxy.c:1573]: rtpp_test(): can't get version of the RTP 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 I have these linee in the kamailio.cfg file loadmodule "rtpproxy.so" # ----- rtpproxy params ----- 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.

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. jp2014 [View Less]

Hello. I use kamailio with last rtpengine and I have 5-7 Seconds voice delay. This happened only for from webphone. But it is not client issue as i see. Wireshark at client side shows that RTP starts as soon I pick up call. So rtp leaves rtpengine and goes to the destination with delay... I use WSS and think that problem at handshake. There are some statisticcs after call finished (as example). You may see that one of streams created after 5 seconds delay. Oct 26 22:15:31 Kamailio2 … [View More]

Hi There, since 4.2 we had the problem that kamailio did not start after a reboot. A "/etc/init.d/kamailio restart" fixxed it.

rtpproxy_manage fails to rewrite SDP
by Igor Potjevlesch 29 Oct '14

29 Oct '14

Hello, I'm working with rtpproxy module for managing calls to a particular route. The thing is that for some calls, the "Connection information" is not rewritten properly whereas another calls, less than 1 second before or after, are properly rewritten. When "cr_route" defines that the call must be route to this carrier, I go to a route in order to make some change: - Keep only PCMA, PCMU, G729a and telephone-event - Depends on the R-URI: o If the uri contains … [View More]

content-length mismatch for kamailio 4.2.x
by andrew 29 Oct '14

29 Oct '14

hi all, kamailio 4.2.x has been released, And I used two endpoint to test kamailio server. I install kamailio 4.2.x on centos 6.5 via 'yum'. One endpoint failed to call another, I captured packets via wireshark, and found that invite method is recognized as error sip signal because of content-length' mismatch. I examined the invite packets, and calculated content-length in invite signal. There is no mistake for the value of content-length. I guess it may be a bug in kamailio 4.2.x. But … [View More]

an issue on terminating dialog for kamailio 4.2.x

hi, I install kamailio 4.2.x on centos 6.5 via 'yum'. One endpoint called another, where one dialog is created, and caller and callee can talk with each other. But when the caller hangup the phone(i.e. send bye to the callee), the callee can't receive the bye message, and the dialog can't be terminated normally. I have captured the packets via wireshark, and uploaded kamailio.cfg and the captured files as attachment. In the captured file, PRACK and BYE message can be sent to kamailio … [View More]
