BYE from CANCLEd path gets forwarded to caller
by Daniel Tryba 30 Jun '15

30 Jun '15

I was testing a scenario whith parallel forking (multiple registers) where 2 endpoints answer near simultaniously. When phone that was just a bit slower hangs up, the BYE gets forwarded to the caller and thus the connection is terminated. This is as far as I know for stateful transactions (t_relay()) I always assumed in this scenario the state machine in kamailio would prevent this kind of behavior by itself. Is there a way to prevent these messages being forwarded?

answer back from wrong IP / Interface
by Mihaly Zachar 27 Jun '15

27 Jun '15

Hi Gents, We have a redirect server based on Kamailio (4.2.3). The server has multiple IPs, but Kamailio is bound to only one address: http://view.xscreenshot.com/9dfdf449a387bdc6f9a719eae3620416 *Sometimes* it answers back from a wrong IP address, here is the proof: http://view.xscreenshot.com/ac661d6b303eda6653b37be7cf65aa65 The interesting thing is that if I do: root@tralab-route-01:~# ip ro get 10.121.24.51 10.121.24.51 via 10.121.43.30 dev vlan486 src 10.121.43.17 cache ipid 0x05ad root@tralab-route-01:~# So the 10.121.43.17 IP is selected, but I *do* expect that Kamailio send back the answer from the same socket where it got the request. What could be the issue ? Why does it do that *sometimes* ? In the majority of the time it works well.. I am not sure why this happens... Thanks, Mitya

don't fragment flag in rtpengine request
by Juha Heinanen 27 Jun '15

27 Jun '15

i was wondering why sometimes requests to rtpengine don't get through and icmp unreachable destination error message is received. it turned out that in these error cases ip packet containing the rtpengine request has 0x02 (don't fragment) flag set even when the packet was bigger than 4 KB. in this case kamailio was running in an amazon container which may be doing something weird. is it somehow possible from the application (= kamailio) to control setting of that flag? -- juha

deb building system
by Victor Seva 26 Jun '15

26 Jun '15

Hello, I would like to inform that the deb nightly builds are going to be disabled. I'm having problems with the actual configuration and until I found the time to fix them the service will be out of order. No new debs will be produced until further notice. Cheers, Victor

limit calls to incoming only?
by Peter Villeneuve 26 Jun '15

26 Jun '15

Hi, Is it possible for Kamailio to restrict certain users (like in a group) to only receive calls but never dial out or send SIP Simple messages outbound, while allowing all other "regular" users to make outgoing calls and text messages as well as receive them? If so, which module do you guys recommend I look into? Cheers, Peter

fix_nated_contact NAT rtpproxy problems
by Vik Killa 25 Jun '15

25 Jun '15

Hello, We are trying to get Kamailio working as an SBC using rtpproxy(); The config seems to work except with some carriers, kamailio does not recognize the ACK because it does not match the contact header of the OK I've been trying to figure out how to get kamailio to send the OK back using the public IP address but I cannot figure out how. I've tried using various deployments of the nathelper module such as fix_nated_contact() set_contact_alias() No matter what though, Kamailio will not change the contact header it receives from FS before sending it back to the carriers. This has become frustrating as I read tutorials that showed this is possible, yet I am unable. Thank you. /V
