Hi all. Have a problem with radius authorization. I'm using auth_radius.so modparams, only path to client file: modparam("auth_radius", "radius_config", "/etc/radiusclient/radiusclient.conf") Freeradius installed and is working properly, radtest authentication from kamailio host succeed . How authorization block looks like: if (!is_present_hf("Authorization")) { xlog("L_NOTICE", "----- Athorization HF is not found - passing the challenge -----\n"); if (nat_uac_test("2")) { force_rport(); } www_challenge("$fd", "1"); exit; if (!radius_www_authorize("$fd","$fU")) { if (nat_uac_test("2")) { force_rport(); } xlog("L_NOTICE", "----- Registeration $au@$ar ($fU) from $si:$sp Rejected. Code: $rc -----\n"); sl_send_reply("401","Unauthorized"); exit; Radius log is filled by rows like: Auth: [digest] Cleartext-Password or Digest-HA1 is required for authentication. Tried to use radius_www_authorize without $fU - didn't change anything. Tried to use www_challenge without qop - didn't change anything. So, this solution is quite simple, but I have a fail while digest authentication. Any ideas? -- -- BR, Donat Zenichev Wnet VoIP team Tel: +380(44) 5-900-808 http://wnet.ua

Kamailio 4.4.4 crash in tcp_read_headers()

by Armen Babikyan

Hello, Over the past few months, I've seen a smattering of kamailio crashes on various systems with identical backtraces: SIGSEGV in tcp_read_headers(), at tcp_read.c line 628. Example here: https://pastebin.com/qJ3ypnVz Note that in frame 0, print *c shows that req->parsed is pointing to an address exactly 8GB lower than req->buf. That req->parsed is pointing to an invalid memory location, crashing kamailio when the location is dereferenced. In other coredumps, I see that req->parsed is pointing to an address exactly 4GB lower than req->buf. Other info: This is Kamailio 4.4.4 on x86_64. I've not had success trying to reproduce this yet. Also worth noting that the crashes seem to be consistently associated with processing traffic from a UA connected over SIP/TCP; I've seen no other transport associated with this crash. Thoughts are welcome. Thanks! Armen

Adding debugger module to kazoo-kamailio

by Joe Baran

I’m hoping that someone might have some suggestions on how to approach this. I’ve been working with kamailio as part of kazoo (via RPM install) and have been attempting to add the debugger module so I can trace things as they pass through kamailio. However, I need some help in determining the most effective way of adding this. Has anyone already done this / have any suggestions? Thanks, Joe

topos module - possible bug

by Pete Kelly

Hi I am using the topos module when bridging 2 networks with Kamailio. The INVITE/200OK part of the transaction is working fine (i.e. the Contact on both sides matches correctly the corresponding network). However when the ACK is sent into Kamailio, instead of realising the next hop is myself and skipping it, Kamailio is sending the ACK directly to itself as a packet, causing the call setup to break. Does anyone have any advice for this situation?

relationship between debian kamailio.service and kamailio.init

by Juha Heinanen

Could someone who knows about systemd tell, what is the relationship between deb/stretch kamailio.service and kamailio.init files? kamailio.service contains kamailio binary argument values and command to start kamailio, but kamailio.init does much more. Why do both exist? -- Juha

RTPEngine a=rtcp-mux

by Igor Olhovskiy

Hi! I’m trying to make RTPEngine to work with calls Browser <-> SIP. Call From SIP to Browser working perfectly, but when calling to SIP from Browser, on 200 OK (sdp) I don’t receive ... a=rtcp-mux ... lines, but it was told to RTPEngine on reply_route to add this. And this line is mandatory for me, cause I don’t control JS softphone on other side Reply route in a case of Browser->SIP call looks like reply_route[REPLY_R] { … rtpengine_answer("internal external UDP/TLS/RTP/SAVPF ICE=force rtcp-mux-offer"); ... } Also I’ve tried with rtcp-mux-accept but still no luck Regards, Igor
