Change in mailing list configuration related to DMARC spam filtering
by Henning Westerholt 22 Sep '23

22 Sep '23

Hello, due to some changes from certain cloud infrastructure provider related to spam filtering with DMARC, we need to change the list manager "mailman" configuration for the following lists: * sr-users * sr-user-es * sr-dev * business * sr-docs * kamailio-announce * the administrative mailing list The change will impact the "From" that is displayed in your email program. Without that change large e-mail providers (Gmail, Microsoft O365) will reject messages from a sender with certain strict DMARC policy. This is already affecting several people on the lists (for example with GitHub notice mails), but over time the problem will certainly increase. Regarding the technical change: We will munge the From: header so it doesn't contain the domain that triggers the DMARC rejection. Essentially, the Mailman list takes ownership of the message and injects its own address into the From: header. This can affect reply-to-sender, although we add the original From: address in the Reply-To: header (or sometimes the Cc: header) to reduce the impact of this. We plan to do this for all emails unconditionally, regardless of their sender DMARC policy, to have an identical behaviour for all users. Please refer to this [1] page for more details. For a general description of DMARC refer to this page [2]. This change should have not a big impact for you, but some users might need to adapt some mail filters. Therefore, we would like to gather feedback on that change from you. We expect that the most visible change is that It will be not possible anymore to just reply by e-mail to mails from GitHub and have them "automatically" added to the discussed issue. This feature was so far used rarely and only from a few people. We plan to implement this change by the end of this week, when its done it will be also shortly announced.

Consulta Envió de comando en forma remota
by damian 07 Jun '22

07 Jun '22

Hola, buenas tardes. Tengo una duda, espero que puedan orientarme o ayudarme. Tengo montado un Sistema de Redirect Server con Kamailio, funcionando OK. Este server lee una tabla que sale de un MYSQL y con el modulo mtree la cargo en memoria. Cuando hago modificaicones en la DB refresco los datos en memoria con el comando: kamcmd mtree.reload mytabla. Ahora bien, hay alguna forma de que haga este reload en forma remota. es decir, no tener que conectarme al server por ssh y tirar el comando localmente. Hay alguna posibilidad de que kamailio este escuchando y hacerle el request de reload? Si lo hay, cuentan con algun ejemplo que puede utilizar de referencia? Saludos.

Usando el modulo UAC
by Javier Valencia 18 Nov '20

18 Nov '20

Buenos días a quién corresponda. He configurando el módulo UAC para usar los "remote registrations" en un Kamailio 4.4.3. Lo tengo todo funcionando a excepción del campo flags al que siempre le pongo un valor 0. Pero cuando Kamailio comienza a lanzar los REGISTER ese campo no se persiste en BBDD. En el archivo kamailio.cfg no he realizado ningún cambio, solamente uso la parte de BBDD. ¿Es un comportamiento normal? ¿Tengo algún parámetro no seteado o mal configurado? Saludos, JV

Algo así: 2020/10/20 19:50:24.415684 SERVER-IP:5060 -> kamailio-IP:5060 INVITE sip:1800123453@kamailio-IP SIP/2.0 Via: SIP/2.0/UDP SERVER-IP:5060;branch=z9hG4bK2c25db99633a0af6 From: <sip:8110300543@SERVER-IP>;tag=0294f31e6fd2a307 To: <sip:1800123453@kamailio-IP> Call-ID: 69c7bc7c63616c6c002139a1@SERVER-IP CSeq: 2140 INVITE Contact: <sip:8110300543@SERVER-IP:5060> Allow: INVITE, ACK, CANCEL, BYE, OPTIONS, INFO, UPDATE, PRACK Supported: timer, linknat Original-Info: tZhbY34NM8c2OWM3 Max-Forwards: 70 User-Agent: VOS3000 V2.1.4.0 Session-Expires: 600 Content-Type: application/sdp Content-Length: 283 v=0 o=- 30656 30656 IN IP4 192.168.20.1 s=VOS3000 c=IN IP4 192.168.20.1 t=0 0 m=audio 27200 RTP/AVP 8 0 18 116 a=rtpmap:8 PCMA/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=ptime:20 a=rtpmap:116 telephone-event/8000 a=fmtp:116 0-15 a=sendrecv # call_incoming.cfg route[did_incoming] { # Lets hardcode for testing purposes $avp(called_number) = $rU; $avp(caller_id)=$fU; $avp(src_ip) = $si; if($rdir(name)=="downstream") { xlog("DID request was incoming call, called number: $rU caller_id: $fU and source_ip $si \n"); $sht(rtpProxy=>mip_$ci)=1; # Validate SIP OK uac_replace_to("sip:1212@kamailio-server-dns:5060"); $ru = "sip:1212@kamailio-server-dns:5060"; if(!t_relay()) { sl_reply_error(); exit; } exit; } Cualquier ayuda será de mucha utilidad, creo pensar que debo buscar el subscriber en la tabla y ahi hacer un forward o algo de esa llamada pero no tengo muy claro como hacerlo.
