Kamailio with NATted RTPproxy
by Jean-Marie Baran 18 Aug '15

18 Aug '15

Hi, I am trying to have RTPproxy works with Kamailio behind a NAT. As it seems RTPproxy cannot handle NAT natively, I installed RTPproxy 1.2.1 by miconda: https://github.com/miconda/rtpproxy Now I am able to make calls, but neither the video nor the audio are present. Wireshark showed that the RTP packets were sent to wrong IPs (private IPs). And this was because of the SDP which contained the wrong IP (fields o= and c=). Then I tried to play with rtpproxy_manage(), and Kamailio replaced the IP in o= and c= by its advertising IP (i.e. its public IP), so the packets from the client behind the NAT were sent to the public address of Kamailio (and then dropped). My question here is what should be the addresses in the SDP when redirected from Kamailio to the client ? Here is the topology when receiving an ACK with SDP: Client <--(2)-- Kamailio <--(1)-- Router (NAT) <--(1)-- Public Internet <--(1)-- Third party router (21.24.12.24) (1): SDP o= 21.24.12.24, c= 21.24.12.24 (2): SDP o= ??, c= ?? (Should it be Kamailio public IP (actually Router IP), or Kamailio private IP, or third party SIP server public IP ?) Cheer, -- *Jean-Marie Baran*

rtpengine rewrite sdp for second time

Hi Carsten, Thanks for your reply! How can I call msg_apply_changes() in right way? If I call msg_apply_changes() for example in route[RELAY] i get error: ERROR: textopsx [textopsx.c:157]: msg_apply_changes_f(): invalid usage - not in request route if I do everything as you suggested in onreply_route (after I get for example SIP 500 message) it doesn't work and my SDP remains unchanged.

Routing re-INVITEs after phone port change
by David Cunningham 18 Aug '15

18 Aug '15

Hello, We have a scenario like this: SUA -> Kamailio with registrar module -> Asterisk A call from the SUA is set up with SIP timers, and after 15 minutes Asterisk sends a re-INVITE to Kamailio to forward on to the SUA. That re-INVITE has a RURI with the address and port of the SUA at the time the call started. Now if the SUA re-registers after the call starts and before the re-INVITE, and is on a new address or port number, then the re-INVITE never gets to the phone. Obviously Kamailio should send the re-INVITE to the new address/port, but is not. The re-INVITE is routed using the lookup() function. Can anyone suggest why this is happening? Thanks in advance, -- David Cunningham, Voisonics http://voisonics.com/ USA: +1 213 221 1092 UK: +44 (0) 20 3298 1642 Australia: +61 (0) 2 8063 9019

Kamailio/Asterisk Integration - MySQL driver error
by Ben Fitzgerald 17 Aug '15

17 Aug '15

Has anyone seen this error before? " ERROR: db_mysql [km_dbase.c:121]: db_mysql_submit_query(): driver error on query: Host '192.168.xxx.xxx is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'" I fixed it using flush hosts but I'm curious why this popped up? Is there a way to limit connections for Kamailio and why am I reaching that limit with *only 2* SIP endpoints? This is not a heavily utilized database by any means.

Edge Proxy, how is it supposed to work?
by Daniel Tryba 17 Aug '15

17 Aug '15

The documentation for outbound contains sample configs for edge proxy and registrar configs: http://kamailio.org/docs/modules/4.2.x/modules/outbound.html I tried to implement these but I don't see anything happen concerning the outbound module. What is supposed to happen to make it work? The main problem I have is that calls for the endpoints coming in from the registrar fail to get past the loose_routing check and fail with a 500 in the default case of the switch. the R-URI contains username/externalip/port from the endpoint, there is 1 route header (containing the edgeproxy ip) but no username/flow-token. So per http://kamailio.org/docs/modules/4.2.x/modules/rr.html#loose-route-id loose_routing returns false: "If a Route: header is found, the function returns 1 and behaves as described in section 16.12 of RFC 3261. There is only one exception: If the request is out-of-dialog (no to-tag) and there is only one Route: header indicating the local proxy, then the Route: header is removed and the function returns FALSE." How should the Path header look when registering? According to http://kamailio.org/docs/modules/4.2.x/modules/path.html#idp3043008 there should be a flowtoken inserted, this is not the case. Just a plain Path: <sip:ip;lr> is added. So when is outbound required? Can anybody confirm that the examples work?

rtpengine rewrite sdp for second time
by Virmantas Variakojis 17 Aug '15

17 Aug '15

Hi, I have a situation like this: I have kamailio with 3 NIC's. I'm sending INVITE to first provider over NIC1. Before sending INVITE I use rtpengine_manage to rewrite sdp body with IP that is on NIC1: rtpengine_manage ("replace-origin replace-session-connection direction=intvlan direction=prov1 ICE=remove"); If first provider fails i want to send INVITE for the same call to second provider. But if i use like this: rtpengine_manage ("replace-origin replace-session-connection direction=intvlan direction=prov2 ICE=remove"); or (because ip of prov1 is allready set): rtpengine_manage ("replace-origin replace-session-connection direction=prov1 direction=prov2 ICE=remove"); rtpengine ignores my changes as said in documentation: "The direction must only be specified in for initial SDP offer; answers or subsequent offers can omit this option." and if I try to set ip like this: rtpengine_manage ("replace-origin replace-session-connection media-address=X.X.X.X ICE=remove"); SDP body is doubled: it leaves old values and adds the new one. What i'm doing wrong or how can I rewrite SDP for second time? Thanks in advance for answer!

multi-process not multi-threading
by Ali Taher 14 Aug '15

14 Aug '15

Hello, Can you please help me to well understand this statement : Kamailio is a multi-process application not multi-threading Does this mean that if we have a machine with one processor of 8 cores , kamailio cannot process more than 1 call at the same time ? Any help would be appreciated. Regards, Ali

Handling Hold
by Fred Posner 14 Aug '15

14 Aug '15

Hello all, Always fun integrating with proprietary pbx's... is there a way that is "generally accepted" as handling hold invites from devices such as Mitel or Toshiba? We're not proxying the media, so these devices are trying to send an Invite to the endpoint when calls are placed on hold.
