SDP_NAT on Retry
by Timo Klecker 08 Jul '14

08 Jul '14

Hello everybody, we have got a problem with sdp-nat on retries of a 200 OK packet. Due to slow response of our trunk the 200 ok is resend (up to 3 times) but sdp-nat is only done on the first two packets. We are running Kamailio 4.1.0 with the following setup: Trunk --> NAT --> Kamailio --> Voip Bridge The rtp stream from the trunk (public ip) is supposed to go to one of our media gateways (behind 1:1 nat). We use sdp_mangle_ip to replace the private IPs of our Mediagateway with the public ones. This goes well with the first 200 OK packet but not with a retry. A.A.A.A (public trunk media IP) B.B.B.B (our public media IP - 1:1 natted to I.I.I.I) INVITE Trunk --> Kamailio Connection Information (c): IN IP4 A.A.A.A INVITE Kamailio --> Voip Bridge Connection Information (c): IN IP4 A.A.A.A 200 OK Kamailio <-- Voip Bridge Connection Information (c): IN IP4 I.I.I.I 200 OK Trunk <-- Kamailio Connection Information (c): IN IP4 B.B.B.B 200 OK Kamailio <-- Voip Bridge Connection Information (c): IN IP4 I.I.I.I 200 OK Trunk <-- Kamailio Connection Information (c): IN IP4 I.I.I.I ACK Trunk --> Kamailio --> Voip Bridge Our configuration used is the following: route[RELAY] { xlog("L_INFO"," In route Block RELAY \n"); # enable additional event routes for forwarded requests if (is_method("INVITE|SUBSCRIBE|UPDATE")) { if(!t_is_set("onreply_route")) t_on_reply("MANAGE_REPLY"); } if (!t_relay()) { xlog("L_NOTICE", " (ROUTE_RELAY) Relay failed, sending error \n"); sl_reply_error(); } exit; } onreply_route[MANAGE_REPLY] { xlog("L_INFO"," In route Block MANAGE_REPLY \n"); if ( isflagset(20) ) { -- we have to do nat route(SDP_NAT); force_send_socket(KAMAILIO_TO_TRUNK_IP); } else { force_send_socket(KAMAILIO_TO_BRIDGE_IP); } } How can we handle the 200 OK retry? Is there a way to do this? Kind regards Timo Klecker

SIP domain translation between providers
by Jeremy Visser 08 Jul '14

08 Jul '14

G'day folks Struggling to work out whether Kamailio can help me or not in this situation, and I hope someone can tell me whether I'm barking up the wrong tree. I have hundreds of users which register to an old legacy Asterisk box that needs retiring. The "users" are customers consisting of VoIP ATAs, PBXes, softphones, and other hardware phones. I've been told I need to retire the Asterisk system in the next month and move customers to our new provider, who provide the SBC themselves (it's a Broadsoft-based system). Obviously a customer once ported to the new provider requires new SIP proxy and SIP domain settings configured in their CPE. For obvious reasons, I cannot require hundreds of customers to change their configuration overnight. However, there is not enough time to assist hundreds of customers changing their SIP proxy/registrar/domain details. So in the meantime I'm trying to work out a transition solution. I cannot simply change my SIP registrar DNS to be a CNAME for the new provider's registrar, as the domain is different, and the new provider doesn't allow domains other than their own to register with them (even if the username/password portion is correct). My new provider has previously told me they are unwilling to accept my old domain whilst authenticating (they are much bigger than me, and I have no power to change them). So I was hoping to use Kamailio and possibly the Path or Dispatch modules to proxy SIP registration to the new provider, rewriting the domain part of the SIP register string as I go But I can't for the life of me work out whether that's even possible. I have spent weeks poring over various Kamailio configurations posted to the interwebs, but nobody seems to have done this before. Specifically the "translation proxy" -- which I am hoping to make Kamailio -- will need to be stateless, and perform no local authentication. Individual registrations will need to be passed through to the new provider (including authentication!), while still translating the domain in the Request-URI, To, From, and various other SIP headers. Because the current legacy Asterisk box has nat=yes set for all users, I will need to proxy media, because if I start proxying SIP traffic to the new provider, I will be confusing their own NAT hacks. I don't understand the documentation for either the Path or Dispatch modules, and the information on the wiki is confusing and poorly written. I am very familiar with SIP, and have no trouble configuring Asterisk, but trying to work with Kamailio is leaving me feeling like an idiot. However, Kamailio's config is very flexible, so despite this I suspect what I'm trying to achieve may be possible. Any pointers in the right direction? Cheers, Jeremy.

Strange avp_check behavior
by Klaus Darilion 08 Jul '14

08 Jul '14

Hi! Kamailio 4.1.4. When using avp_check with fnmatch and AVP the result is always TRUE if it is true for 1 time. It only happens with $avp(), but not with $var(). Is this a bug or some special behavior of AVPs? xlog("L_ERR", "======= with $$avp(...)================"); $avp(rpid) = "+499539110"; $avp(pattern) = "+499539[2-5]"; # NO MATCH if (avp_check("$avp(rpid)", "fm/$avp(pattern)/g")) { xlog("L_ERR", "$avp(rpid) matches $avp(pattern): YES"); } else { xlog("L_ERR", "$avp(rpid) matches $avp(pattern): NO"); } $avp(pattern) = "+499539*"; # MATCH if (avp_check("$avp(rpid)", "fm/$avp(pattern)/g")) { xlog("L_ERR", "$avp(rpid) matches $avp(pattern): YES"); } else { xlog("L_ERR", "$avp(rpid) matches $avp(pattern): NO"); } $avp(pattern) = "+499539[2-5]"; # NO MATCH if (avp_check("$avp(rpid)", "fm/$avp(pattern)/g")) { xlog("L_ERR", "$avp(rpid) matches $avp(pattern): YES"); } else { xlog("L_ERR", "$avp(rpid) matches $avp(pattern): NO"); } xlog("L_ERR", "======= with $$var(...)================"); $var(rpid) = "+499539110"; $var(pattern) = "+499539[2-5]"; # NO MATCH if (avp_check("$var(rpid)", "fm/$var(pattern)/g")) { xlog("L_ERR", "$var(rpid) matches $var(pattern): YES"); } else { xlog("L_ERR", "$var(rpid) matches $var(pattern): NO"); } $var(pattern) = "+499539*"; # MATCH if (avp_check("$var(rpid)", "fm/$var(pattern)/g")) { xlog("L_ERR", "$var(rpid) matches $var(pattern): YES"); } else { xlog("L_ERR", "$var(rpid) matches $var(pattern): NO"); } $var(pattern) = "+499539[2-5]"; # NO MATCH if (avp_check("$var(rpid)", "fm/$var(pattern)/g")) { xlog("L_ERR", "$var(rpid) matches $var(pattern): YES"); } else { xlog("L_ERR", "$var(rpid) matches $var(pattern): NO"); } --> The result is: <script>: ======= with $avp(...)================ <script>: +499539110 matches +499539[2-5]: NO <script>: +499539110 matches +499539*: YES <script>: +499539110 matches +499539[2-5]: YES <script>: ======= with $var(...)================ <script>: +499539110 matches +499539[2-5]: NO <script>: +499539110 matches +499539*: YES <script>: +499539110 matches +499539[2-5]: NO Thanks Klaus

Measuring Response Time for a SIP Message
by AliReza Khoshgoftar Monfared 07 Jul '14

07 Jul '14

Hi, I am trying to do two types of measurements on a packet (say an INVITE or BYE) that arrives at a kamailio proxy. 1) The time that packet is spending in Kamailio to be processed 2) The total time from when the packet arrives at the machine that runs the proxy till it leaves that machine. I believe kamailio shall be able to help me with (1) and for (2) , I may need to use some linux tools Have anybody tried to measure response time with either definition? and in case that you have, how have you done it? Thanks Alireza
