Best way to log incoming/outgoing sip messages?
by Pranathi Venkatayogi 23 Jan '17

23 Jan '17

Hi, What is the best way to get a complete dump of incoming/outgoing SIP messages of Kamailio server? I encountered “SIPTrace” module, but it writes to database. Is there a way we can write to syslog instead? Thanks Pranathi

Kamailio IMS Secure Websocket closes connection
by Serhat Guler 22 Jan '17

22 Jan '17

Dear all, I am trying to make a call between 2 sipml5 client over WSS. Everything works fine and as expected when using WS. While using WSS, the clients are registered successfully, but when I make a call, the called party is disconnected from the network and the caller gets "User offline" message. There a wireshark capture here: https://drive.google.com/file/d/0B6LMw8kmoAMYMGhrYXNUVXJySEk/view?usp=shari… The call is made from Alice to Bob, the port Nrs: 4060: PCSCF, 5060:ICSCF, and 6060 SCSCF. WWS is running on 4443. The error message that is shown in Firefox console: "The connection to wss://192.168.0.11:4443/ was interrupted while the page was loading." Thanks in advance, Serhat

Siremis Multi domain
by Annus Fictus 20 Jan '17

20 Jan '17

Hi, I think Siremis not work correctly in a multi domain scenario if the extension number are the same for two domains. I explain a little more. I have two extension: 1 200(a)sip1.domain.org 2 200(a)sip2.domain.org On the Siremis I create the user 200 with the SIPuser role. When I login with this user, and go to subscriber data i can see bots extensions. I think is relate to this select on kamailio database: .....SELECT T0.id, T0.username, T0.domain, T0.password, T0.email_address, T0.ha1, T0.ha1b, T0.rpid FROM `subscriber` T0 WHERE T0.username='200' LIMIT 10 Any hint? Regards

UAC authentication
by anfecora 20 Jan '17

20 Jan '17

can someone please guide me where to find the usage of auc module, thanks in advance. I am registering the uac in one end then i want to forward that registration to an external registrar, if i use $du some domain, some of the ipv6 info is going to be forwarded, i need to make it look more like an a b2bua than a outbound proxy therefore i need to use the auc module(also i need to cover all ipv6 info since i am proxying from ipv4 to ipv6). i am able to register the client to kamailio, then kamailio send the registration to the external registrar, but when the registrar sends back the challenge uac does not reply, any ideas how can achieve this. uac(linphone etc) --registration--->kamailio(registrar module)------register(uac)--->SBC sbc----invite---->kamailio(lookup)---------invite---->uac(linphone etc) this is the code i am using. # Handle SIP registrations route[REGISTRAR] { xlog("REGISTERING "); if (is_method("REGISTER")) { if(isflagset(FLT_NATS)) { setbflag(FLB_NATB); # uncomment next line to do SIP NAT pinging ## setbflag(FLB_NATSIPPING); } if(af==INET6) setbflag(FLB_IPV6); xlog("IT IS IPV6"); if (!save("location")) sl_reply_error(); route(REGSBCFWD); exit; } } route[REGSBCFWD]{ xlog("CREATING OTHER LEG TO THE SBC"); if(!is_method("REGISTER")) { return; } xlog("CREATING PACKAGE $si -- $fU-- $au--$du-- $tU --$ru"); $var(rip) = "sip.somedomain.com"; $uac_req(method)="REGISTER"; $uac_req(ruri)="sip:" + $var(rip) + ":" + "5060"; $uac_req(furi)="sip:" + $tU + "@" + $var(rip); $uac_req(turi)="sip:" + $tU + "@" + $var(rip); $uac_req(hdrs)="Contact: <sip:" + $tU + "@" + "10.0.0.222" + ":" "5060" + ">\r\n"; if($sel(contact.expires) != $null) $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $sel(contact.expires) + "\r\n"; else $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $hdr(Expires) + "\r\n"; uac_req_send(); } REGISTER sip:sip.somedomain.com:5060 SIP/2.0.

Return body/string from Perl library
by David Cunningham 20 Jan '17

20 Jan '17

Hello, We are using Kamailio's perl module and want our custom library to set the body on a SIP message. Is it possible to set a SIP message body from within Perl, or can we return a string to the Kamailio configuration to then use with set_body()? Thanks for any advice. -- David Cunningham, Voisonics http://voisonics.com/ USA: +1 213 221 1092 Australia: +61 (0) 2 8063 9019

Phone number formats per country
by Daniel-Constantin Mierla 19 Jan '17

19 Jan '17

Hello, slightly off-topic, but related to voip -- does anyone have a link that can quickly share to a site with up to date details about phone numbering plans for as many country as possible? Ideally to include the toll and premium number prefixes, the split between mobile and fixed lines if it is the case.

ds_is_from_list and NAPTR / SRV
by Björn Bylander 19 Jan '17

19 Jan '17

Hello, I’m trying to resolve an issue with the ds_is_from_list function from the dispatcher module. I’m calling it as follows: ds_is_from_list(”42”, "3", "sip:sip.foo.bar”) This makes Kamailio log an error: ERROR: dispatcher [dispatch.c:2327]: ds_is_addr_from_list(): could not resolve sip.foo.bar sip.foo.bar doesn’t have any A records but there are NAPTR and SRV records: $ host -t naptr sip.foo.bar sip.foo.bar has NAPTR record 20 0 "s" "SIP+D2T" "" _sip._tcp.sip.foo.bar. sip.foo.bar has NAPTR record 10 0 "s" "SIP+D2U" "" _sip._udp.sip.foo.bar. $ host -t srv _sip._tcp.sip.foo.bar _sip._tcp.sip.foo.bar has SRV record 10 0 5060 sip1.foo.bar. _sip._tcp.sip.foo.bar has SRV record 10 0 5060 sip2.foo.bar. $ host -t srv _sip._udp.sip.foo.bar _sip._udp.sip.foo.bar has SRV record 10 0 5060 sip2.foo.bar. _sip._udp.sip.foo.bar has SRV record 10 0 5060 sip1.foo.bar. $ host sip1.foo.bar. sip1.foo.bar has address 10.47.11.1 $ host sip2.foo.bar. sip2.foo.bar has address 10.47.11.2 The following DNS options are set: dns_srv_lb = yes dns_try_naptr = yes dns_naptr_ignore_rfc = no The Kamailio version is 4.2.8 (installed from the Debian binary package) on Debian Wheezy. Shouldn’t ds_is_from_list be able to resolve the NAPTR and SRV records? Can I change anything to be able to use ds_is_from_list with the specified domain? Thanks, Björn Bylander
