kamailio with NAT IP and DNS loadbalance
by 吴妙灵 10 Oct '17

10 Oct '17

Hi, Here are same problems in my configuration of kamailio server. I have two kamailio server (both have a NAT IP and a lan IP), and I use DNS to keep loadbalance.When sending message to another account , if NAT IP which is returned by DNS, is not the same as receiver account, kamailio server sends 404 not found error. I really have no idea how to set the configuration when using DNS loadbalance to return two NAT IP. Thank you , I'm looking forward from you! Sincerely yours Ada WU

INFO: qq.com domain was blocked due to very high volume of spam
by Daniel-Constantin Mierla 09 Oct '17

Hello, writing to inform everyone that currently the qq.com domain is blacklisted by the kamailio.org email server due to high volume of spam sent to many admin addresses and mailing lists. Spamassassin had very hard time digesting and filtering, as content kept changing and addresses were random. I didn't get the chance yet to check if we have subscribers with this domain, so, as a fast lane, if you use it and don't have the possibility to quickly switch to another email server domain, write me to try to whitelist the address. Hopefully, if anyone is affected, there is not much inconvenience, but it was the only quick solution that could be applied for the moment.

In master branch there is already subst_body(): - https://github.com/kamailio/kamailio/blob/master/src/modules/textops/textop… I will add more as I get time before 5.1 release. Anyhow, even in 5.0 is a generic kemi function that allows executing any kamailio.cfg function, respectively: KSR.x.modf(func, param1, ...) In your case, try: KSR.x.modf("replace_body_all", "a=sendonly", "a=sendrecv") You should be careful with KSR.x.modf(...), because is some cases it may result in pkg leak due to cfg param fixup. So, do some tests and be sure that pkg memory stats are not indicating a leak.

rtpengine_manage in tsilo INVRESUME sends delete instead of offer
by Anthony Alba 06 Oct '17

Hi, I am using tsilo and push notification recipe from https://www.kamailio.org/events/2015-KamailioWorld/Day2/20-Federico.Cabiddu… On resume of a suspended transaction rtpengine_manage() is sending delete instead of offer. In the routing block INVRESUME after t_continue(): route[INVRESUME] { lookup("location"); rtpengine_manage("DTLS=off ICE=remove"); t_relay(); ts_store(); $sht(vtp=>stored::$rU) = 1; } I expect rtpengine_manage() to send offer since this is a Request+SDP; instead it sends delete to rtpengine with garbage Call-ID. If I replace rtpengine_manage() with rtpengine_offer() then it works. rtpengine (the actual media proxy) sees Received command 'delete' from 192.168.1.755:49851 Call-ID to delete not found which is totally bogus of course. rtpengine_offer() works fine but wondering why rtpengine_manage() goes berserk here.

rtpengine - optional srtp
by Daniel-Constantin Mierla 06 Oct '17

06 Oct '17

Hello, wondering if anyone has a quick answer to spare some time searching the web or source code -- is there a way to offer optional SRTP (just SDES is also fine) in SDP with RTPEngine? The use case is when the target device is not yet known to support (or not) SRTP. There are couple of ways in specs or practices (e.g., RFC5939/6871, or advertising crypto attributes on RTP/AVP stream, or offering two streams one RTP and one SRTP), I am looking to find if it is possible to do it with RTPEngine and which of the options are supported/what are the parameters for doing it...

A "success_route" as counterpart to "failure_route" available?
by Kristijan Vrban 05 Oct '17

05 Oct '17

Hello, i need a "success_route" which does the same as "failure_route", but only for positiv 2xx reply. Is something like this available? Background: i forward REGISTER to external registrar server, and only what to save the location on positiv reply to REGISTER. Without doing the authentication myself. I tried to save the location in onreply_route, but then the contact of the external registrar server is saved. So i need a status check in the REQUEST_ROUTE. Best Kristijan
