Advertise NAT IP address causing Multiple SIP INVITEs is that expected ?
by Adil Mafzool Zaka 15 Mar '23

15 Mar '23

Hi I am using advertise in the listen interface for our NATed setup within AWS. Using following listen statement in kamailio: - version: kamailio 5.5.1 listen=udp:10.0.1.4:5060 advertise 3X.1XX.1XX.2XX:5060 dispatcher.list 1 sip:10.0.4.23:5060 8 10 weight=11 #FreeSwitch 1 We are seeing that kamailio (10.0.1.4) is sending two SIP INVITEs via dispatcher to FreeSwitch at 10.0.4.23 which seems strange or is it expected behaviour? (As seen below) SIP INVITE Request: - WAN Address >> Kamailio AWS NATed address >> FreeSwitch 1 1X.2X.2X.2X >> 3X.1XX.1XX.2XX 10.0.1.4 >> 10.0.4.23 10.0.1.4 >> 10.0.4.23 Many thanks Regards Muhammad Zaka

Use Kamailio and RTPEngine to play wav file as early media to announce a server maintenance
by jhayhoe＠liquidweb.com 15 Mar '23

15 Mar '23

I am looking to configure Kamailio and RTPEngine to play a wav file for any new calls during a scheduled asterisk server maintenance. I have set up the following within route{} to send the call to a early_media route based on a variable that I can set on the server using kamcmd. route { ... if ($sht(config=>maint)=="1") { if (is_method("INVITE") && !has_totag()) { xlog ("L_INFO","Ongoing maintenance. Call-ID:$ci | Method: $rm"); route(early_media); } } ... } route[early_media] { xlog("Maintenance: handling early_media\n"); rtpengine_manage("direction=external direction=external"); $var(body) = $(rb{re.subst,/(IP4.).*/\1##server IP redacted##/g}); set_reply_body($var(body), "application/sdp"); t_send_reply("183", "Session Progress"); sleep(2); unblock_dtmf("all"); play_media("file=/etc/kamailio/media/maintenance.wav"); sleep(21); rtpengine_delete(); t_reply("480","Temporarily Unavailable"); } This mostly works as I hear the recorded message in place of the ringing tone when a call is processed by kamailio and then a busy signal is heard as part of the 480 reply at the end. The sleep's are in place to match the duration of the recorded message as otherwise the 480 is sent immediately following the start of the play_media. Feel free to let me know if there is a better solution to wait the duration of the media file and then proceed with processing instead of using sleep(). Is there a way to instead send a CANCEL or a BYE instead of a 480 after the wav file is played? I tried using t_cancel_callid("$ci", "$cs", "0") as well as a dlg_bye("all") at the end of the early_media route and neither seemed to send any headers out.

by nutxase 14 Mar '23

Hi All I have setup kamailio using dispatcher to proxy registrations from the UAC to asterisk but when asterisk sends an incoming call it does not seem to keep the path header and therefore kamailio sends 404 is there anyway around this? Thanks Sent with [Proton Mail](https://proton.me/) secure email.

Use MySQL connector instead of mariadb connector
by suchendra adiga 14 Mar '23

14 Mar '23

Hi, I have been working on setting up the database with the Kamailio server. But facing a problem when my db user has configured with SSL required. But I learnt that there is no support to enable the SSL in mariadb connector. So I am thinking of using the MySQL connector instead. Is there anyway I could configure the kamailio to use MySQL instead of Mariadb? Thanks and regards, Suchendra

Hello I have an issue with Rx in my VolTE call Flow. Please refer to picture and pcap in annex. I am using same rtp engine at origination and termination. I am sending rtpmanage for invite and 183 session progress at both origination and termination. My issue is that Rx is not sending for the proper media flow component to PCRF. At origination it is considering a media flow between A 50034 and RTPEngine 49186 (instead of considering RTP Engine Port 49152) At Termination it is considering a media flow between B 50054 and RTPEngine 49132 (instead of considering RTP EnginePort 49170) Any idea why?

use_dns_failover and dispatcher
by Lars Jansson 10 Mar '23

10 Mar '23

Hi, I had the intention to route calls to some SRV destinations via dispatcher and to other SRV destinations via DNS lookup and 'use_dns_failover=on'. Currently in a route block using dispatcher two out of three targets within the SRV destination are unavailable (by intention). During my tests to the dispatcher destination I have found that: A) If I have 'use_dns_failover=on' this setting "overrules" the dispatcher routing and the unavailable targets are also tried before DNS failover finds the available target. B) If I have 'use_dns_failover=off' the dispatcher routing logic works as expected and the call is always routed to the only available target directly, making use of the result of the dispatcher OPTIONS pinging. -- So my conclusion is now that you have to choose: Either use dispatcher routing, or use DNS failover based routing. - I'm fine with this, but I just would like to know if my conclusion is correct, or if there is actually a way to use dispacther for some SRV destinations and DNS failover for other SRV destinations. Regards, Lars
