fix_nated_contact and IPv6
by Sebastian Damm 27 Oct '17

27 Oct '17

Hi, I'm trying to set up a Kamailio (4.1.3) server which converts between IPv6 and IPv4. Everything looks pretty good. Now I have a test client which sends packets via IPv6, but in contact header, SDP etc. there are still IPv4 addresses. (This comes from some converting from v4 to v6 earlier.) Thus, Kamailio tries to do a fix_nated_contact(). But after fixing, the Contact URI is wrong. Example: inbound Contact: <sip:bob@192.168.8.132> outbound Contact: <sip:bob@1234:1234:0:1234:0:0:0:2> The correct way of transforming the Contact URI would be: Contact: <sip:bob@[1234:1234:0:1234:0:0:0:2]> This incorrect Contact URI doesn't hurt first, but when the called party wants to hang up the call, it addresses the URI from Contact header, and Kamailio can't parse the Request URI: Jan 22 12:03:48 router /usr/sbin/kamailio[21309]: ERROR: pv [pv_core.c:304]: pv_get_ruri_attr(): failed to parse the R-URI Jan 22 12:03:48 router /usr/sbin/kamailio[21309]: ERROR: rr [loose.c:934]: loose_route(): failed to parse Request URI Jan 22 12:03:48 router /usr/sbin/kamailio[21309]: ERROR: domain [domain.c:140]: is_uri_host_local(): error while parsing R-URI Is this a bug in the nathelper module? Was it never meant to handle IPv6 addresses? Or do I understand something wrong? Best Regards, Sebastian

Set timeout before 180/183 reply arrived
by Yu Boot 27 Oct '17

27 Oct '17

Hello. Have a problem with some uplinks. They sometimes respond "100 Trying" on initial INVITE and... that's all. A caller waits for about 30 seconds and cancel a call deciding there's something wrong with our network. How to use failure route when 180/183 answers don't arrive in 5 or 10 seconds after INVITE?

by Brandon Shiers 26 Oct '17

26 Oct '17

I have a client that has an old Kamailio 1.5 installation. They would like to migrate and get off their old hardware and old OS. I've read the upgrade page for the 1.5.x migration to 3.0.0, are there any gotchas to be aware of other than what's there?

Regarding rtimer usage under specific condition
by RAJA SREE RATHNA gomathinayagam 26 Oct '17

26 Oct '17

Hello, While going through the rtimer module we noticed that it execute the routing function repeatedly after the given interval of time. But our specification is to execute the routing function only once and timer should be enabled based on specific condition. Also there is no enable or disable option for rtimer module as in timer module, whether rtimer module can be enabled based on specific condition.If it is possible could you please suggest the solution. Thanks & Regards, Rathna.

shared dialogs
by : Paolo Visintin - Time-Net S.r.l. 26 Oct '17

26 Oct '17

Hi kamailio users, I'm wondering if there's something already done with shared dialog among more kamailio instances, in order to manage branches initalized by another kamailio instance. A ctually seems not possible (also with db mode) because kamailio is looking into caller/callee_sock and if it's different does not manage in a "standard" failover environment (master / slave) with vIP and keepalived and $fs = VIRTUAL_IP everything is working fine but in a distributed environment this could not happen as the relay is managed by a kamailio proxy Thanks in advance Paolo
