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

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

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 ?

DNS resolution with ipops

by harneet singh

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

db_redis and ursloc - problem after restarting kamailio

by Koldo Aingeru

Hi, I've encountered a problem using db_redis for location, we recently migrated to redis from mysql and just found out this yesterday. We are using the usrloc module with db_mode = 2, so the location info is written to redis every 60 seconds. When restarting, Kamailio reads all the contacts and loads them into memory, but for some contacts it loads the “methods” key with an incorrect value. If in the REGISTER there are no methods kamailio saves it with methods= -1: { "jsonrpc": "2.0", "result": { "AoR": “zzzzzzz", "Contacts": [{ "Contact": { "Address": "sip:1540305477794@W.X.Y.Z:5060", "Expires": 2752, "Q": -1, "Call-ID": "7d3965a85bfd0e88-32357(a)W.X.Y.Z", "CSeq": 11, "User-Agent": “xxxxxxx", "Received": "sip:W.X.Y.Z:5060", "Path": "<sip:A.B.C.D;lr;received=sip:W.X.Y.Z:5060>", "State": "CS_SYNC", "Flags": 0, "CFlags": 64, "Socket": “udp:A.B.C.D:5060", "Methods": -1, "Ruid": "uloc-644a176b-6472-4641", "Instance": "[not set]", "Reg-Id": 0, "Server-Id": 0, "Tcpconn-Id": -1, "Keepalive": 1, "Last-Keepalive": 1684246829, "Last-Modified": 1684246829 } }] }, "id": 19286 } But when restarting kamailio, the same contacts has a methods= 0 { "jsonrpc": "2.0", "result": { "AoR": “zzzzzzz", "Contacts": [{ "Contact": { "Address": "sip:1540305477794@W.X.Y.Z:5060", "Expires": 2697, "Q": -1, "Call-ID": "7d3965a85bfd0e88-32357(a)W.X.Y.Z", "CSeq": 11, "User-Agent": “xxxxxxx", "Received": "sip:W.X.Y.Z:5060", "Path": "<sip:A.B.C.D;lr;received=sip:W.X.Y.Z:5060>", "State": "CS_SYNC", "Flags": 0, "CFlags": 64, "Socket": “udp:A.B.C.D:5060", "Methods”: 0, "Ruid": "uloc-644a176b-6472-4641", "Instance": "[not set]", "Reg-Id": 0, "Server-Id": 0, "Tcpconn-Id": -1, "Keepalive": 1, "Last-Keepalive": 1684246829, "Last-Modified": 1684246829 } }] }, "id": 19286 } In the schema file for redis the key is correctly set as int and in redis I can see it saved as -1. So when a call comes in, the lookup() function returns a -2 as it doesn’t support the INVITE method and the call fails. This is happening in kamailio 5.2.8 and kamailio 5.2.1 (old versions, I know, we are working on updating it); with mysql as a backend it works perfectly after a restart. We do have the param method_filtering=1 , changing to 0 makes it works. We seem to have this since forever and for what I can see, is not unusual as is in the default kamailio.cfg provided (even the default value for it is 0). Has anyone else encountered this?

Contact changes, caller dialog attributes and NAT traversal

by Alex Balashov

Hi, When I modify INVITEs with set_contact_alias() / add_contact_alias(), this is not preserved in dialog data, and therefore not honoured in BYEs locally generated due to dialog timeout. For example, if the initial INVITE contained: Contact: sip:line1@192.168.1.100 and, after transit, became: Contact: <sip:line1@192.168.1.100>;alias=1.1.1.1~25844~1 There is no ;alias value stored in the caller dialog data, just the original URI + parameters. A related problem: I tried to work around this by storing an alias in dialog user variables, e.g. $dlg_var(alternate_ct) = $_s($si~$sp~$prid) and in fact, I am able to recover this value later: event_route[tm:local-request] { if($dlg_var(alternate_ct) ne $null) { $ru = $ru + ";alias=" + $dlg_var(alternate_ct); handle_ruri_alias(); } } And in fact, if I print the value of $du after calling handle_ruri_alias(), I can see that it is modified. However, this seems to have no effect on where the request actually goes at the network and transport level. I assume this is because the event_route does not actually allow one to overwrite elements of the spoofed request, and that its essential attributes have been pre-populated elsewhere. Nevertheless, the effect is that these BYEs do not reach NAT'd endpoints. Any suggestions are appreciated!
