Kamailio OPTIONS Round-Trip
by Soltanici Ilie 27 Mar '20

27 Mar '20

Hi, With Asterisk, we are able to get some peer round-trip connection statistic by setting qualify=yes for the specified peer. It sends periodic OPTIONS to the peer and calculates the time round trip time. It's something like - "Status: OK (30 ms)". Is there any way to achieve this in Kamailio by using nathelper module, or any other? Thank you.

Hello, I have in production environment with 4 proxies using DMQ to sync terminal registers and the DMQ configuration parameters is following: loadmodule "dmq.so" #modparam("dmq", "server_address", "sip:MY_IP_ADDRESS:MY_PORT_ADDRESS") modparam("dmq", "notification_address", "DMQ_HOSTS") modparam("dmq", "multi_notify", 1) modparam("dmq", "num_workers", 4) In the lab environment with the same configuration that in prod, I can simulate this problem with 12000 terminal REGISTERS and, when doing … [View More]

Multiple advertise addresses per socket
by Sergiu Pojoga 25 Mar '20

25 Mar '20

Hi there, Question: how can I advertise and later match multiple FQDNs per socket? Example: auto_aliases=no alias="mydomain.net":5060 alias="mydomain.net":5061 alias="client1.mydomain.net":5060 alias="client1.mydomain.net":5061 # looks like I can advertise only one address per socket? listen=udp:65.65.65.65:5060 advertise "mydomain.net":5060 listen=tls:65.65.65.65:5061 advertise "mydomain.net":5061 Adding RR before relaying downstream like so: record_route_preset("client1.mydomain.net:5061;… [View More]

Kamailio 5.3.2 - Signal 11 on startup
by José Seabra 25 Mar '20

25 Mar '20

Hello there, I'm facing an issue with kamailio 5.3.2 when it is starting up, it breaks with signal 11 and generates a coredump file: - https://pastebin.com/FSqyGFp8 This seems to be something related to dmq module, kamailio exits with signal 11 when it receives a DMQ notification_peer message. I did a few more tests and I noticed that problem disappears if I configure DMQ with one worker only, which takes me to think that it's something related to concurrency. Best regards -- Cumprimentos José Seabra

about kamailio.cfg NAT test
by Juha Heinanen 24 Mar '20

24 Mar '20

In kamailio/etc/kamailio.cfg NAT test is based on nat_uac_test("19"). 19 includes test 16: 16 - Test if the source port is different from the port in the “Via” header. If the “Via” header contains no port, it uses the default SIP port 5060 Based on a couple of tests using baresip, looks like that results in false positive when UA connects to SIP proxy via TCP. An example: T 2020/03/24 13:57:12.685441 192.26.134.10:38940 -> 192.26.134.1:5060 [AP] #127 REGISTER sip:test.tutpro.com … [View More]

Transformations - urlencode
by João Vitor Arruda 24 Mar '20

24 Mar '20

Hello, I was looking in the transformation documentation ( https://www.kamailio.org/wiki/cookbooks/devel/transformations) something to URL encode a pv or var for use in a HTTP query but was not able to find it. Digging a bit in the source code I found that "s.urlencode.param" actually exists and from my initial tests it works just fine. I'm wondering if there is any reason why this is not mentioned in the documentation of if it should not be used at all. Thanks, Joao Arruda

Manipulating contacts header results in a malformed SIP packet
by Andrew White 23 Mar '20

23 Mar '20

Hi all, Hope everyone is well, and looking forward to seeing you all whenever Kamailio World ends up being! I’m currently dealing with an issue which I’m unsure if it’s due to my own implementation, or a bug. When attempting to manipulate the Contact header via app_ruby, the SIP message I send ends up being malformed. Here’s the code I’m using: def replace_contact_header(uri) #KSR::HDR.remove("Contact") if KSR::HDR.is_present('Contact') > 0 #KSR::HDR.append("Contact: #{uri}\r\n") … [View More]

Pike Module Clarification
by JR Richardson 23 Mar '20

23 Mar '20

Hi All, Please clarify the pike settings for SIP message count, the module Doc reports: ---- modparam("pike", "sampling_time_unit", 10) modparam("pike", "reqs_density_per_unit", 30) How many requests should be allowed per sampling_time_unit before blocking all the incoming request from that IP. Practically, the blocking limit is between ( let's have x=reqs_density_per_unit) x and 3*x for IPv4 addresses and between x and 8*x for IPv6 addresses. ----- So the example above the … [View More]

set_advertised_address not accepting vars
by Sergiu Pojoga 22 Mar '20

22 Mar '20

Hi there, The function doesn't appear to accept vars. For example, set_advertised_address("$var(someaddress)") results in a VIA of string $var(someaddress), instead of var's value. https://www.kamailio.org/wiki/cookbooks/5.3.x/core#set_advertised_address kamailio 5.3.2 (x86_64/linux) 0bed10 Cheers. --Sergiu

pipelimit: inexistent pipe error logs
by Nuno Ferreira 20 Mar '20

20 Mar '20

Hi all, I'm using pipelimit with the "clean_unused" option to get rid of pipes that are not used for quite some time. At the same time we are monitoring pipelimit with a jsonrpc call similar to: # curl --header 'Content-Type: application/json' --data-binary '{"id": 1, "jsonrpc": "2.0", "method": "pl.list", "params": ["pipe_INVITE"]' http://127.0.0.1:8000/RPC Reply: { "jsonrpc": "2.0", "error": { "code": 400, "message": "Unknown pipe id pipe_INVITE" }, "id": 1 } The … [View More]
