search_append_body?
by Steve Wilkins 04 Aug '20

04 Aug '20

Hello, Does search_append_body require an "\r\n" in the attribute that is being added? If I don't use a "\r\n", it appears to look correct in the trace, however one provider says the attribute that was added was just a continuation of the prior attribute, which Wireshark does not show to be the case. Thank you,

topoh problem with bye from trunk
by mohsen khashei 04 Aug '20

Hi all. I use topoh module for topology hiding and this is my config for topoh: modparam("topoh", "mask_key", "my key") modparam("topoh", "mask_callid", 1) modparam("topoh", "callid_prefix", "!!:") modparam("topoh", "sanity_checks", 1) modparam("topoh", "mask_ip", "x.x.x.x") modparam("topoh", "uri_prefix_checks", 1) modparam("topoh", "uparam_name", "line") modparam("topoh", "uparam_prefix", "sr-") modparam("topoh", "vparam_name", "branch") modparam("topoh", "vparam_prefix", "z9hG4bKsr-") and also i use: modparam("dialog", "lreq_callee_headers", "TH: dlh\r\n") for dialog module. my calls come from asterisk and routed to the carrier(sip trunk) and vice versa, when i make a call from asterisk every thing works fine until the call hanged up from the carrier. at that modemt the kamailio send an 481 call/leg transaction does not exist. if call dropped bye the asterisk user everything works fine. how can i solve this?

Setting up MSFT Teams SBC <> SIP trunk but forwarding ACK and CANCEL messages
by Daniel van der Tang 02 Aug '20

02 Aug '20

Hello, I'm setting up a Kamailio MSFT Teams SBC that is connected to our SIP trunk provider. This server is directly connected to the Internet and not behind a NAT routing. It is successfully processing invites from both sides (MSFT Teams and SIP trunk). Unfortunately the ACKs and CANCEL messages are not relaying to Teams. In the sipdump i can't find these messages. Does anyone see what I am doing wrong?

Manipulating SDP IP for Inbound Calls
by Edward Romanenco 02 Aug '20

02 Aug '20

Hey guys, I am working on a project involving Kamailio dockerezation, which is meant to run alongside Freeswitch and RTPEngine containers, on the basis of a Docker-Compose file which is launched on top of a CentOS 7.7 host system. Anyway, I would love to know if there is any way to manipulate / mask the IP addresses that are being appended to a status 183 response for an incoming invite. For some reason which I am trying to figure out in parallel, Freeswitch uses the local network bridge subnet instead of the defined external RTP IPs, and I was wondering - Can I manipulate them using Kamailio? I know that Mangler module can do it for outbound calls, but can I do the same for inbound? v=0. o=FreeSWITCH 1595974788 1595974789 IN IP4 172.18.0.40. s=FreeSWITCH. c=IN IP4 172.18.0.40. t=0 0. m=audio 45878 RTP/AVP 8 101. a=rtpmap:8 PCMA/8000. a=rtpmap:101 telephone-event/8000. a=fmtp:101 0-16 Edward

Issue with kamctl after upgrading to 5.3.4
by Igor Potjevlesh 31 Jul '20

31 Jul '20

Hello there! I'm having trouble with kamctl since I upgraded to 5.3.4. The command is working fine with root user but not with another user. The problem seems to be that the command try to access to /var/run/kamailio/kamailio_rpc.fifo even if the file exists. I guess it's a permission problem. But I was thinking that FIFO is no more used. Only jsonrpcs. How can I fix that? Regards, Igor. -- L'absence de virus dans ce courrier électronique a été vérifiée par le logiciel antivirus Avast. https://www.avast.com/antivirus

publishing hash values for download files of releases
by Daniel-Constantin Mierla 30 Jul '20

30 Jul '20

Hello, being discussed during the last devel meetings, I published the md5, sha1 and sha256 hash values for the tarballs with sources and i386 binaries we make available for download on kamailio.org on each release -- e.g., for 5.4.0: * https://www.kamailio.org/pub/kamailio/5.4.0/src/ * https://www.kamailio.org/pub/kamailio/5.4.0/bin/ Before making a more official announcement about it and adding to the download/install docs, I want to discuss a little bit here and get to the right solution to publish these hash values. For the moment I put them in a single file, adding -checksums.txt to the tarball name, listing inside all 3 hashes as computed by md5sum, sha1sum and sha256sum. That because I couldn't decide alone if there is sort of a standard on how to do it. Couple of projects I checked they just list the hash values on the html page with the link to download file. Others have dedicated files per hashing type, named like MD5SUMS, SHA1SUMS and SHA256SUMS, containing hash values for all downloadable files in the folder. Then, asterisk projects publishes 3 files, asterisk-VERSION.{md5,sha1,sha256}, corresponding to the tar.gz file they made available. Freeswitch publishes more than one archive file type, so it makes available files like freeswitch-VERSION.EXT.{md5,sha1,sha256}, where EXT can be tar.gz, tar.xz, zip ... My questions now. What kind of files with hash values people here are used with? Any variants that tends to be (or become the standard)? Any tools you are aware of for automatically checking the integrity with one of these specific hash files (like, if I have the tarball and the hashes file in the same folder and run it, it gives the ok/not-ok, without me having to do md5/sha1/sha256 manually and check "by eye" the values)?

Kamailio IMS with custom AVPs
by Gaston Siffert 28 Jul '20

28 Jul '20

Hello all, I am investigating on how to integrate few IMS modules in the Platform I am working on. At the moment the main drawback for me is to find a way to export data from the Diameter Answers. In the RFC 7155, it’s written that the AA-Answer could have a list of customisable fields. While looking at the implementation of the Rx_AAR (IMS QOS) in Kamailio, the module does not seems to export any of the fields from the AA-Answer except the return code. The same applies for the implementation of I_perform_location_information_request (IMS ICSCF) in Kamailio. Do you have any recommendation on how to export the other AVPs from the Diameter Answers ? Instead of IMS QOS and IMS ICSCF, I could use diameter_request_async (IMS Diameter Server) to make my own AAR and LIR, but is it the recommended practice ? https://tools.ietf.org/html/rfc7155#section-3.2 <https://tools.ietf.org/html/rfc7155#section-3.2> https://kamailio.org/docs/modules/5.0.x/modules/ims_qos.html#idp18760852 <https://kamailio.org/docs/modules/5.0.x/modules/ims_qos.html#idp18760852> https://kamailio.org/docs/modules/4.4.x/modules/ims_icscf.html#idp39432196 <https://kamailio.org/docs/modules/4.4.x/modules/ims_icscf.html#idp39432196> https://www.kamailio.org/docs/modules/devel/modules/ims_diameter_server.htm… <https://www.kamailio.org/docs/modules/devel/modules/ims_diameter_server.htm…> Best regards, Gaston Siffert

Using GeoIP2 AS Lookup?
by Mark Boyce 27 Jul '20

27 Jul '20

Hi all Just looking at the latest GeoIP2 MaxMind databases (now requires registration, but still free) and noticed that they also include the AS (ISP) lookup one in the free offering. Wondering if this is another way to facilitate better security for users on dynamic IP. Typically working from home these days. So, rather than just limiting an end device to a country we could limit it to a particular ISP within that country. Has anyone tried this? Have I missed a reason why this wouldn’t help? Admin overhead not worth it? Thoughts? Best regards Mark -- Mark Boyce Dark Origins Ltd

kamailio 5.3.5 - none local route header
by Jonathan Hunter 27 Jul '20

27 Jul '20

Hi Guys, Sorry if this is too generic or silly a question but I am testing kamailio 5.3.5 within Azure and its behind NAT. I am having an issue with passing an ACK from our internal side back out to the carrier side and it appears having run loose_route a none local route-header is consistently being removed by kamailio at this point. ie Route: <sip:CARRIER_IP;lr> Is this normal or configuration related? As I am unsure within what scenario I would remove a route header which doesnt contain the local Proxy IP. Please can someone advise? Many thanks Jon Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows 10

Redis error: Server closed the connection / nbd_redis / kamailio 5.3.5
by Karsten Horsmann 27 Jul '20

27 Jul '20

Hi everyone, I get some strange errors from nbd_redis but my setup is working. kamailio 5.3.5 on CentOS 7.7.1908. Redis-Server is an haproxy frontend that pushed the stuff to an redis-sentinel cluster (with and really old version redis-3.2.1-2.el7.remi.x86_64). Any ideas on that?
