Tell topos to create 'duplicate' route header from rr header with same ip

by Benoit Panizzon

Hi Gang I'm having another go with a dedicated kamailio running topos to replace a B2BUA SBC. I came across this situation: Server Topology: Kamaiolio SBC (topos) <=> Kamailio Registrar <=> Kamailio Router (DLG + CDRS) Core IP Address 10.0.0.1 Registrar IP 10.0.0.2 Two different CPE are registered on Registrar via SBC One CPE is calling the other CPE So the path the call is taking is: CPE A => SBC => Registrar => Core => Registrar => SBC => CPE B Invite A => B goes through, no issue. 180 Ringing, required 100rel B => A requires the route to be recorded therefore contains 3 record route statements: Record Route: <sip:10.0.0.2;lr> Record Route: <sip:10.0.0.1;lr> Record Route: <sip:10.0.0.2;lr> To ensure answer will get route back to the registrar => core => registrar and then the contact pointing to the SBC with topos to restore the last hop. Ringing B => A works as expected and is answered by A with PRACK. topos would now need set Route: in this PRACK message, according to the received Record Route Header. Unfortunately I fear Topos 'removes' the routes with duplicate host ip. I only get: Route: <sip:10.0.0.2> Route: <sip:10.0.0.1> Causing the Core not to be able to route the PRACK back to the registrar. To test, which line is being dropped, I added an mark to each one and determined the 3rd Record Router is being dropped by topos, probably considered a duplicate. I found no setting of the 'do not perform record route header dupe detection'. Interestingly, when I look at the database field topos_d.b_rr all three entries are present in the correct order. Has anyone come over the same issue and found a solution? Maybe related to: https://github.com/kamailio/kamailio/issues/3778 ?

Last line of onreply_route (drops reply)

by James Browne

Hi all I noticed, in my config, that if the last line of the reply_route is a function that does not succeed, then the SIP response is not relayed and kamailio throws an error. I've searched documentation to indicate why this might be, but I can't find anything, so this looks to me like a bug. I use 5.8.1 for testing. Here's a sample config that shows what goes wrong. #################### #!KAMAILIO listen=udp:203.0.113.57:5060 debug=1 loadmodule "textops" request_route{exit;} reply_route{remove_hf_re("^X-Custom");} #################### Here's a sample SIP message that works. When I send this to udp:203.0.113.57:5060, kamailio relays it. #################### SIP/2.0 200 Testing Via: SIP/2.0/UDP 203.0.113.57:5060;branch=z9hG4bK-d8754z Via: SIP/2.0/UDP 198.18.0.157:5060;branch=z9hG4bK-d8754z T: <sip:c@s>;tag=676fbf45 F: <sip:c@s>;tag=676fbf45 X-Custom: lkjdfl i: testing-XXX CSeq: 1 INFO l: 0 #################### If I then remove the X-Custom header field from the SIP reply and try again, the message does not get relayed and I see this in the log. 5(1356) WARNING: <core> [core/receive.c:605]: receive_msg(): error while trying onreply script If I put a log command after the remove_hf_re(), then the message gets relayed. It looks like the reply_route always fails if the last function is not successful. Is this normal or is it a bug? James

Question regarding error message "failed to add new socket to the fd list"

by Floimair Florian

Hi! We have recently had issues with one of our Production Kamailios. When those happened, the log was filled with the following message: CRITICAL: <core> [core/tcp_main.c:4528]: handle_new_connect(): failed to add new socket to the fd list Now I wonder what the best approach is to prevent this. We are using TCP/TLS only and I think this might be related to the file ulimit, but I am not sure about that. Shared memory is set to 512MB Can you give me a hint on what to look for? Thank you very much! P.S.: Sorry, I accidentally replied to a previous post of a different topic before which is totally unrelated (I think I should stop working for today 😉) FLORIAN FLOIMAIR Software Development - Symphony Cloud Services Commend International GmbH Saalachstrasse 51 5020 Salzburg, Austria [signature_2072127332] commend.com LG Salzburg / FN 178618z

apt-key deprecation

by tom＠tomlynn.com

When I look at the debian repositories maintained by the project, there are instructions to import the public key of the repository for apt using this command: wget -O http://deb.kamailio.org/kamailiodebkey.gpg | sudo apt-key add - which results in: Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)). gpg: no valid OpenPGP data found. Is there an alternate method that can be posted in the repository that will get better results? Thank you, TL

[db_unixodbc] how to specify the database with unixodbc？

by 17603019528＠163.com

Hi Dear Community, I want to use db_unixodbc to connect to the dm8 database. Although I use Opensips, I found that this module db_unixodbc, Kamailio and Opensips are the same.
