double record route from INVITE
by Wilkins, Steve 16 Sep '18

16 Sep '18

Hi Mojtaba, But when I send the 'BYE' doesn't the double Record-Route from the 'INVITE' (from IOS) need to be there, so that IOS can find it's Proxies and complete the transaction and send back a '200 OK'? Thank you,

double record route?
by Wilkins, Steve 16 Sep '18

16 Sep '18

Good Morning All, Is there any way to add a double record route? I tried adding a second record route and I always only get the first one added. I have tried record_route(....), and record_route_advertised_address(...), but I still only get the first record route added. Thank you, -Steve

Hi! I did this tutorial: https://sonnguyen.ws/install-kamailio-debianubuntu/ When I try to start the daemon I get: # systemctl start kamailio Job for kamailio.service failed because the control process exited with error code. See "systemctl status kamailio.service" and "journalctl -xe" for details. Doing systemctl status kamailio shows: # systemctl status kamailio ● kamailio.service - Kamailio (OpenSER) - the Open Source SIP Server Loaded: loaded (/lib/systemd/system/kamailio.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Fri 2018-09-14 20:26:25 BST; 44s ago Process: 29482 ExecStart=/usr/sbin/kamailio -P /var/run/kamailio/kamailio.pid -f $CFGFILE -m $SHM_MEMORY -M $PKG_MEMORY -u $USER -g $GROUP (code=exited, status=255) Main PID: 24331 (code=exited, status=0/SUCCESS) Sep 14 20:26:25 thunix.org /usr/sbin/kamailio[29484]: ERROR: <core> [db.c:318]: db_do_init2(): could not add connection to the pool Sep 14 20:26:25 thunix.org /usr/sbin/kamailio[29484]: ERROR: usrloc [dlist.c:654]: register_udomain(): failed to open database connection Sep 14 20:26:25 thunix.org /usr/sbin/kamailio[29484]: ERROR: registrar [reg_mod.c:566]: domain_fixup(): failed to register domain Sep 14 20:26:25 thunix.org /usr/sbin/kamailio[29484]: ERROR: <core> [route.c:1153]: fix_actions(): fixing failed (code=-1) at cfg:/etc/kamailio/kamailio.cfg:646 Sep 14 20:26:25 thunix.org /usr/sbin/kamailio[29484]: ERROR: <core> [route.c:1153]: fix_actions(): fixing failed (code=-1) at cfg:/etc/kamailio/kamailio.cfg:649 Sep 14 20:26:25 thunix.org /usr/sbin/kamailio[29484]: INFO: <core> [sctp_core.c:53]: sctp_core_destroy(): SCTP API not initialized Sep 14 20:26:25 thunix.org systemd[1]: kamailio.service: Control process exited, code=exited status=255 Sep 14 20:26:25 thunix.org systemd[1]: Failed to start Kamailio (OpenSER) - the Open Source SIP Server.

Record-Route Parameters
by Duarte Rocha 15 Sep '18

15 Sep '18

Greetings, My Kamailio has 2 IP's and, as such, it will generate two Record-Routes when the Request is relayed. I want to add one parameter to one of the Record Routes and another parameter to the other Record-Route. However, if i use add_rr_param() it will automatically add the parameters to the two Record-Route Headers. Is there a way to do what i want without me re-writing the headers directly ? Cheers, Duarte Rocha

Record Route Parameters
by Duarte Rocha 15 Sep '18

15 Sep '18

Greetings, I have Kamailio as an SBC with mutiple IP's and I need to save some information in the first Invite about the routing made internally in the Kamailio. I'm thinking about adding some parameters to Record-Route and retrieve them in the Route header. Is this safe ? Can I be sure that those parameters won't be deleted or changed? Best Regards, Duarte Rocha

14 Sep '18

Hi. Does anybody know what kamailio core maxbuffer parameter means? And is there any conjunction with system net.core.rmem_max parameter? Doc is obscure for me "The size in bytes not to be exceeded during the auto-probing procedure of descovering the maximum buffer size for receiving UDP messages. " -- Savolainen Dmitri

Forward SIP request between two Kamailio servers
by Nathanael Eneroth 14 Sep '18

14 Sep '18

Hi,? I have a simulation setup of 4 VMs in Virtual Box - two UAs and two Kamailio servers. The first UA will register to KAM1, and the second UA will regsiter to KAM2. See the Figure below. UA1<--->KAM1<---->KAM2<---->UA2 int1 int1 int3 int3 int2 int2 I would like KAM1 to forward all SIP requests destined to int3 via KAM2 and vice versa. I am aware of the routing logic in 'kamailio.cfg', but i find rather excessive. Pseudo code of what i'm trying to achieve: if (is_method("INVITE")) { if(dst_ip == int3) set_next_kamailio_server(KAM2) } Or: if (is_method("INVITE")) { if(callee is unkown) ask_kamailio_server(KAM2) } Thanks for all the help
