DISABLE SDP MEDIA STREAMS
by Patrick Karton 29 May '23

29 May '23

Hello kamailio community, i know its an unusual query but i would like to know if there is a cleaner/proper.right way to disable some (or all) media streams in SDP. i have come with a solution by sdpops module with subst_body function like this. route[SDP_DISABLE_UNAUTHORIZED_MEDIA]{ # disable text,media and video media streams subst_body('#^m=(video|text|audio)[ ]+[0-9/]+(.*)$#m=\1 0 \2#ig'); # update originator ip address subst_body('#^o=([^ ]+)[ ]+([^ ]+)[ ]+([^ ]+)[ ]+([^ ]+)[ ]+([^ ]+)[ ]+([^ ]+)$#o=\1 \2 \3 \4 \5 7.7.7.7#ig'); # 1 2 2 4 5 6 # name sid snumber network net-type addr # update connection ip address subst_body('#^c=([^ ]+)[ ]+([^ ]+)[ ]+([^ ]+)$#c=\1 \2 7.7.7.7#ig'); # 1 2 3 # network net-type addr #remove all media attributes sdp_remove_line_by_prefix("a=fmtp"); sdp_remove_line_by_prefix("a=X-"); sdp_remove_line_by_prefix("a=rtcp"); sdp_remove_line_by_prefix("a=ssrc"); sdp_remove_line_by_prefix("a=sendrecv"); sdp_remove_line_by_prefix("a=sendonly"); sdp_remove_line_by_prefix("a=recvonly"); sdp_remove_line_by_prefix("a=inactive"); sdp_remove_line_by_prefix("b="); } is it the right way to do it. if not can someone provide me an alternative solution. Thanks :)

Re: [sr-dev] Troubles with outbound kamailio call to other server
by Henning Westerholt 26 May '23

26 May '23

Hello (added sr-users, as its probably more a usage question). The SIP message (the BYE) cannot be parsed apparently. From the log it looks that there is an invalid character in the first line. Do a network trace to analyse the packets that its actually send and try to get some more clues from that.

Consistent huntable responses based on failure_route question
by John Hardiman 25 May '23

25 May '23

Hi Kamailio list, I hope you are all well? I am looking for some assistance on a specific error I am trying to work around. Kamailio 5.5.3 - Ubuntu 20.04 Kemi Python script (but I think this is more default failure_route behaviour) Dispatcher module which hunts to a group of FreeSWITCH that I have configured to send 503 responses on. My scenario is fairly simple, I am trying to respond back to a carrier for huntable responses (503 specifically) by calling a failure route below: def ksr_failure_manage(self, msg): if KSR.tm.t_any_timeout()>0 : self.ksr_send_reply_clear_rtpengine(msg, 503, "Timeout to destination") KSR.err("Timeout to Invite for %s from IP %s" % (KSR.pv.get("$ci"),KSR.pv.get("$si"))) return 1 else: self.ksr_send_reply_clear_rtpengine(msg, 503, "Unknown error failover to next node") KSR.err("Failed but not timeout for %s from IP %s" % (KSR.pv.get("$ci"),KSR.pv.get("$si"))) return 1 This works and a 503 with the correct message is sent if the invite doesn't get a response after 2 seconds. (My specific test case here) # Timers for call setup 2 minutes for any 1xx provisional response received # If no invite response received in 2 seconds end the call as per failure route. KSR.tm.t_set_fr(120000, 2000) self.ksr_route_relay(msg) KSR.tm.t_on_failure("ksr_failure_manage") return -255 The issue is after a few more milliseconds after my initial 503 a 408 is sent. Also after the failover if the carrier tries the same Kamailio again it gets a 500 rather than a 408. 408: [cid:image001.png@01D98F15.CD07DCB0] 500: [cid:image002.png@01D98F15.CD07DCB0] My steps to get around this have been to change the default tm code to 503 below, but this has not changed the default response and the above behaviour unfortunately: # ----- tm params ----- # auto-discard branches from previous serial forking leg modparam("tm", "failure_reply_mode", 3) # setting default reason code and response for general errors to allow failover. modparam("tm", "default_code", 503) modparam("tm", "default_reason", "Unknown reason try next node") My question is: How can I make sure my failure route is the final response here. Or if I cannot make sure of this, how can I change the default mapped response to be a consistent SIP response (503 specifically) Many thanks in advance as I am scratching my head on this one a bit. John.

Override listen advertise address
by Calvin E. 25 May '23

25 May '23

Using 5.6.x, a scenario designed for a public IP now needs to support life in the cloud behind NAT. I'd like to avoid having two listeners to separate on-net from off-net traffic. In a HA scenario, it would be nice to have only one floating IP. Is it possible to use the same local address and port for external/public and internal/private traffic? Should set_advertised_address() override the listen advertise address? Initial testing did not produce the expected result. I want to make sure I'm following a sane pattern before going down a rabbit hole. The idea is to toggle the advertised address by checking if the sender or recipient is rfc1918(). For the dispatcher module, is it possible to use socket names like below? In testing it appeared that only one of the two names was valid. listen=udp:10.0.0.10:5060 name "onnet" listen=udp:10.0.0.10:5060 advertise 11.11.11.11:5060 name "offnet"

lost module: best practice handling delay caused by held / lis procedure?
by Benoit Panizzon 25 May '23

25 May '23

Hi gang In 2024, Switzerland will start using NG112 (NG911) procedures to transmit the caller location via Geolocation URL via LIS Server to a PSAP. So time to start testing this on my devel plattform. Kamailio ships with the lost module which looks promising. In short, the Procedure is as follows: Customer calls emergency number. Kamailio performs a http request to our inhouse HELD server with the identification of the calling customer. HELD server looks up the location of the caller and pushes a HELD XML object to the Swiss LIS Server, which then is queried by the emergency PSAP receiving the call. LIS server return and URL. HELD server returns the URL to Kamailio. Kamailio adds Geolocation Header with that URL and relays the call. This takes some time and as the call is not yet being relayed while waiting for the held request to complete, there is no 100 trying being sent and the emergency call is bound to time out. So, shall I call t_reply("100","Performing HELD lkup") before calling the lost module? Or is there a better way?

mk_proxy(): could not resolve hostname
by ajosebar＠gmail.com 23 May '23

23 May '23

I have Kamailio 5.6 on Debian 11. I need to use the function forward within a routing block in my configuration file: forward("udp:192.168.28.51:5060"); But when I start the kamailio service I got: CRITICAL: [core/proxy.c:264]: mk_proxy(): could not resolve hostname: "udp:192.168.28.51:5060" The same occurs when I use the dns nane : forward("udp:raspberry3.emtelco.co:5060"); Any ideas ? Regards

DNS resolution with ipops
by harneet singh 22 May '23

22 May '23

Hi Experts, I am planning to use *dns_query*() API from the ipops module, which I understand from some documentation that it internally uses *getaddrinfo*(). I wanted to check if someone can comment on the DNS Cache mechanism in this case. * Does Kamailio retain any *dns cache* while using this API, or would it be actually doing the resolution for each call. * In light of the above, does Kamailio honour the *TTL value i*n response to the DNS Query? Regards, Harneet Singh -- "Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth" - Sir Arthur Conan Doyle
