I really want to use top hide using dialog module but having very difficult time.. [UA]------[Opensips]-----[Asterisk] I want to hide UA so Asterisk doesn't know its IP. I have following config, Please correct me if anything wrong in my config, Problem is if callee whoever connected to asterisk hangup call it doesn't not know where to send BYE because of top hiding remove all return routes.. i am surprise how it is working with other folks? something must be wrong in my config then.. if (loose_route() || match_dialog()) { if ($DLG_status==NULL) { xlog(" cannot match request to a dialog \n"); # something wrong - might want to drop such requests } if (is_method("BYE") { setflag(ACC_DO); # do accounting ... setflag(ACC_FAILED); # ... even if the transaction fails acc_aaa_request("Internally generated BYE"); end_media_session(); } else if (is_method("INVITE")) { # even if in most of the cases is useless, do RR for # re-INVITEs alos, as some buggy clients do change route set # during the dialog. record_route(); } .... .... if ( uri=~"^sip:[0-9]*@.*") { uac_replace_from("sip:4545@65.xxx.xxx.xxx"); t_on_failure("3"); resetflag(7); topology_hiding(); t_relay( "udp:65.xxx.xxx.xxx" );

switch kamailio to domain

by Mihai Marin

Hello Sirs, The RLS module is eating my life. I just managed to make it work 2 months ago and now is not working anymore after I tried to put the kamailio under domain (until now it was simple ip). I don't understand why is not working but I saw a big difference that I don't understand: My environment: - the domain "domain.com" is pointing to the web server - kamailio is hosted under sip.domain.com - DNS has domain.com A record for web server's ip, sip.domain.com A record for kamailio's ip and SRV record for _sip._tcp.domain.com poting to sip.domain.dom Problem: kamailio presence is not working anymore and I think, the error is: grep_sock_info - checking if host==us: 11==14 && [domain.com] == [xx.xx.xx.xx witch is the sip.domain.com IP] If, I change domain.com in DNS to point on the same ip as sip.domain.com RLS is working. This, I can't understand. Can anyone explain me why is not working using this configuration? Also, the RLS is working if i change my domain to be sip.domain.com (ex: sip:user@sip.domain.com). Thank you. Best regards, Mihai M

force_send_socket in event route tm:local-request

by Kristian F. Høgh

Hi, Our kamailio 4.0.6 proxy uses pua/pua_dialoginfo and an external presence server. The PUBLISH requests generated by pua* appear in tm:local-request event route. Before sending, we call set_advertised_address and force_send_socket. Still the requests have the IP address from the first "listen=" as source and Via address. The requests are send out using the correct interface and no errors are logged. When forwarding SUBSCRIBE requests received from clients, force_send_socket before t_relay_to_udp do work as expected. mhomed=1 solves the issue, but I prefer force_send_socket. Regards, Kristian Høgh Uni-tel

Kamailio script editor

by Grant Bagdasarian

Hello, What editor do most of you use for editing the kamailio config script? I'm using notepad, which works fine, but sometimes I wish I had something like text coloring and other useful stuff found in most scripting editors. Are there perhaps any plans for developing an editor for the kamailio config script? With code completion, etc. Regards, Grant

CNXCC curious case

by Kelvin Chua

I am using cnxcc_set_max_channels and set the max channels to 1 after the 1st call goes through and hangs up, the 2nd one would be blocked even if there are no more active dialogs. could it be a dialog state issue? Kelvin Chua

Re: [SR-Users] automatic string to int conversion for rtpengine flags failed - rtpproxy_offer() does not change sdp when called in branch_route

by Olli Heiskanen

Hi, The source for this string to int conversion error was found, it was just a minor glitch in an if statement! Man, I feel stupid... Anyways, the problem about calls not going through still persists. This I located to the rtpengine_offer() call in a branch route. The sdp is not changed and this results in Kamailio forking away until it can't. In my test case there is a webrtc client calling another webrtc client. Here I use Kamailio 4.1.5, rtpengine and rtpproxy-ng module. My branch route looks like this: branch_route[MANAGE_RTPENGINE_BRANCH] { xlog("L_INFO", "MANAGE_RTPENGINE_BRANCH: new branch [$T_branch_idx] to $ru\n"); xlog("L_INFO", "MANAGE_RTPENGINE_BRANCH: rtpengine_offer_flags = $avp(rtpengine_offer_flags) and mline = $avp(mline)"); if ($avp(rtpengine_offer_flags) != "") { xlog("L_INFO","MANAGE_RTPENGINE_BRANCH: rtpengine_offer with $avp(rtpengine_offer_flags)"); rtpproxy_offer($avp(rtpengine_offer_flags)); t_on_reply("RTPPROXY_REPLY"); } else { xlog("L_ERR","MANAGE_RTPENGINE_BRANCH but rtp_offer_flags is EMPTY! "); } } And this is what I get in the kamailio log: Aug 20 21:47:58 u363id562 kamailio[28376]: ALERT: <script>: UA_FAILURE: SAVPF found, setting flags using RTP/AVP in offer and RTP/SAVPF in answer Aug 20 21:47:58 u363id562 kamailio[28376]: INFO: <script>: UA_FAILURE: hooked to RTPPROXY_REPLY reply_route and MANAGE_RTPENGINE_BRANCH branch_route, offer flags: froc-sp Aug 20 21:47:58 u363id562 kamailio[28376]: INFO: <script>: RELAY: hooked to manage_failure, now relaying...

Generate SIP MESSAGE in Kamailio

by Grant Bagdasarian

Hello, Is it possible for Kamailio to generate a SIP MESSAGE message when receiving a HTTP request? Take the content of the HTTP message and form it into a SIP MESSAGE and route it to a certain destination? I can't find a module that does this, or I'm just blind.. :) Regards, Grant
