WARNING: <core> [local_timer.c:83]: _local_timer_dist_tl(): 0 expire timer added"?

by Anthony Messina

Good day. Is anyone able to let me in on what this means "WARNING: <core> [local_timer.c:83]: _local_timer_dist_tl(): 0 expire timer added"? I just started seeing this after pulling down 5c1a9df from git and it seems like something that I probably don't want happening. -- Anthony - https://messinet.com/ - https://messinet.com/~amessina/gallery 8F89 5E72 8DF0 BCF0 10BE 9967 92DC 35DC B001 4A4E

Kamailio as a SIP softphone to WebRTC/SIP-over-websockets proxy?

by Rion Carter

I'm pretty new to SIP, RTP/SRTP, WebRTC and Websockets, so I hope this question is coherent. I have a group of SIP Softphones that need to connect to a WebRTC/SIP-over-Websockets server. Can Kamailio be configured to let me do this? Any examples, tutorials or documentation would be appreciated. I'm trying to determine how feasible this task is. :) Thanks!

kamctl: command not available

by Thomas Baeumer

Hi there, I want to use kamctl to monitor the state of a sip-proxy. I just have no idea which commands are available or should i use "kamctl mi" or "kamctl fifo" commands. Google dont give helpful links for that. Im am using kamailio 4.2.3+wheezy on a Debian wheezy and kamctrl dont work: # kamctl fifo uptime Control engine 'FIFO' loaded entering fifo_cmd uptime 500 command 'uptime' not available FIFO command was: :uptime:kamailio_receiver_19959 # kamctl fifo which Control engine 'FIFO' loaded entering fifo_cmd which 500 command 'which' not available FIFO command was: :which:kamailio_receiver_19985 # kamctl mi which Control engine 'FIFO' loaded entering fifo_cmd which 500 command 'which' not available FIFO command was: :which:kamailio_receiver_20016 here is my config: # grep -i fifo kamailio.cfg loadmodule "mi_fifo.so" modparam("mi_fifo", "fifo_name", "/tmp/kamailio_fifo") modparam("mi_fifo", "fifo_user", "kamailio") modparam("mi_fifo", "fifo_mode", 0640) # ls -la /tmp/kam* srw-r----- 1 kamailio root 0 Feb 27 12:39 /tmp/kamailio_ctl prw-r----- 1 kamailio kamailio 0 Feb 27 14:25 /tmp/kamailio_fifo The only known command what is working is to look into a hashtable: # kamctl mi sht_dump foo Control engine 'FIFO' loaded entering fifo_cmd sht_dump foo Entry:: 135 sip:0049xxxxxxxxxxx@sip.domain.tld:: 1 Entry:: 205 sip:0049yyyyyyyyyyy@sip.domain.tld:: 1 FIFO command was: :sht_dump:kamailio_receiver_20144 foo any idea what is wrong? and is there a documentation how to use "kamcrl mi" and "kamctl fifo"?

Keeping Registrations alive in IPv6 scenarios

by Sebastian Damm

Hi, while testing IPv6 with customers, we fell over quite a few cases, where customers aren't reachable on inbound calls most of the time. And digging into this, we found the home router firewall as the cause for those problems. Normally, you would think, all the NAT problems cease when switching to IPv6. But actually, right now I don't know how to fix that problem. In IPv4 NAT scenarios, we would flag the customer during the registration, and Kamailio would send NAT pings (those 4 bytes of UDP junk) every few seconds to keep the firewall in the NAT router open. And that worked pretty great. Now we have IPv6. We don't have NAT. But we still have a home router in front of SIP devices, with a firewall. And this firewall will allow outbound traffic. But after a few seconds it won't allow incoming connections anymore. And the routers I have seen so far don't have a configurable firewall where you could allow inbound traffic from our server. Unfortunately, only our load balancer is IPv6, our registrar is still IPv4 only. And the loadbalancer doesn't know anything about registrations and which customer needs an IPv6 keepalive. Does anyone have a hint, how to keep the IPv6 registrations alive? Thanks in advance. Best Regards, Sebastian

TEXTOPS parser problem with binary data in MIME body

by Federico San Martín

Hi Klaus, did you find a solution to this problem? I'm working with SIP-I and having the same issue with Binary encoding. I need to encode a 0x00 value and when the config script gets to that point, it breaks. If I encode any other hex value it's fine. This is the config part I'm using: route[INSERT_ACM]{ if(has_body()){ # Save the SDP body for future reference $var(sdp_body) = $rb; replace_body_atonce("^.+$", ""); remove_hf("Content-Type"); append_hf("MIME-Version: 1.0\r\n", "Content-Length"); append_hf("Content-Type: multipart/mixed; boundary=unique-boundary-1\r\n", "Allow"); replace_body_atonce("^.+$", "--unique-boundary-1\r\nContent-Disposition: signal; handling=optional\r\nContent-Type: application/isup; version=itu-t92+\r\n\r\n'\x06''\x02''\x04''\x01''\x29''\x01''\x01''\x00'\r\n-unique-boundary-1\r\n"); msg_apply_changes(); replace_body_all("\047", ""); append_body_part("$var(sdp_body)","application/sdp"); } return; } I tried with the escape character \0 which should be translated to ASCII hex value '00' but it's parsed as ASCII literal values \0...

See my previous email. your previous email didn't say anything about the results. That's why I asked. Be sure you don't have those spaces that are in the email you wrote. Also, I had more parenthesis in the parameter of the subst_uri(). Or you can try the alternative with: if($rz=="sips") { $ru = "sip" + $(ru{s.substr,4,0}); } I asked for more details from the backtrace to confirm that what I found is the cause for the crash in this case -- see one of my previous emails from today.

If it crashes, then you get a corefile -- in the logs it says the name of the file. It is usually located in / or in the path you gave to -w parameter. After you reproduced the crash, locate the corefile and run gdb like: gdb /path/to/kamailio /path/to/corefile bt full The /path/to/kamailio should be /usr/sbin/kamailio if you installed from rpms. If you have improvements to init or sysconfig kamailio file, send a patch and we will include the changes in kamailio repository.
