Many instances of "new URI shorter than old URI" in log
by Alex Villacís Lasso 15 Jul '14

Jun 27 15:28:42 elx /usr/sbin/kamailio[25189]: ERROR: uac [replace.c:590]: restore_uri(): new URI shorter than old URI Jun 27 15:28:44 elx /usr/sbin/kamailio[25187]: ERROR: uac [replace.c:590]: restore_uri(): new URI shorter than old URI Jun 27 15:28:48 elx /usr/sbin/kamailio[25188]: ERROR: uac [replace.c:590]: restore_uri(): new URI shorter than old URI Jun 27 15:28:49 elx /usr/sbin/kamailio[25188]: ERROR: uac [replace.c:590]: restore_uri(): new URI shorter than old URI I am not really sure of what this message is supposed to indicate. It looks something related to uac_restore_[from,to] functions, but some debugging statements just before the use show that the message is not originating from there. This message is showing up hundreds of times per day.

set_rtp_proxy_set behaviour
by Igor Potjevlesch 15 Jul '14

15 Jul '14

Hello, I set two entries of rtpproxy like : modparam("rtpproxy", "rtpproxy_sock", "1 == udp:127.0.0.1:7722") modparam("rtpproxy", "rtpproxy_sock", "2 == udp:127.0.0.1:7723") For a particular case, I want to use the second RTPProxy and the first one as the default one. If in a conditional block I set set_rtp_proxy("2"), all other call to rtpproxy_manage will use the first RTPProxy? Or there is a load-balancing introduce by default. Regards, Igor.

Routing calls to Asterisk using dispatch
by Olli Heiskanen 15 Jul '14

15 Jul '14

Hello, I've started playing with an idea to add multiple asterisk servers and using dispatcher to balance the sip load between them. I added the code according to dispatcher module documentation ( http://www.kamailio.org/docs/modules/4.2.x/modules/dispatcher.html), but I think there's something off in my setup: kamctl ul output shows 2 AORs for one client: AOR:: 770(a)testers.com Contact:: sip:770@2.2.2.2:64340;rinstance=c634da314e12385f;transport=UDP Q= Expires:: 3221 Callid:: ZTE1MWYwYzM3NGNjNjMxMmEzM2JjYWNmNzQyZTdiNGI. Cseq:: 2 User-agent:: Z 3.2.21357 r21367 State:: CS_SYNC Flags:: 0 Cflag:: 0 Socket:: udp:1.1.1.1:5060 Methods:: 5087 Ruid:: uloc-53bfe447-35ae-2a2 Reg-Id:: 0 Last-Keepalive:: 1405174150 Last-Modified:: 1405174150 AOR:: 770(a)1.1.1.1 Contact:: sip:770@1.1.1.1:5070 Q= Expires:: 68 Callid:: 327fcf07641f80006e962821112a61b5(a)testers.com Cseq:: 754 User-agent:: Asterisk PBX 11.10.2 State:: CS_SYNC Flags:: 0 Cflag:: 0 Socket:: udp:1.1.1.1:5060 Methods:: 4294967295 Ruid:: uloc-53bfe447-35af-a82 Reg-Id:: 0 Last-Keepalive:: 1405174477 Last-Modified:: 1405174477 I don't think I should be seeing an AOR for 770 where Contact is the public address of my server (here 1.1.1.1) and User-Agent which is Asterisk. I'm using Asterisk Realtime integration, and by what I can tell the sip messages are going nicely, client authenticates with Kamailio and sends this message to Asterisk (which is on the same machine; Kamailio at 5060 and Asterisk at 5070): 1.1.1.1.sip > 1.1.1.1.vtsas: SIP, length: 374 REGISTER sip:1.1.1.1:5070 SIP/2.0 Via: SIP/2.0/UDP 1.1.1.1;branch=z9hG4bKbc8a.f4473947000000000000000000000000.0 To: <sip:770@1.1.1.1> From: <sip:770@1.1.1.1>;tag=4a9c3f1c98b9f1c5704acfd1770d93d2-d0c1 CSeq: 10 REGISTER Call-ID: 7ffa0191-13742(a)1.1.1.1 Max-Forwards: 70 Content-Length: 0 Contact: <sip:770@1.1.1.1:5060> Expires: 3600 Currently I can make calls from 770 to 123 which is an Asterisk extension that answers, plays hello world and hangs up. However I can't call another sip clients when I route calls through Asterisk, they do work fine if I don't use Asterisk for handling calls, but I'd like Kamailio to be in the role of proxy/loadbalancer and Asterisk to handle calls. My config is the simple default config, added with realtime stuff and then dispatcher according to the documentation. I wonder if there's something wrong in the REGISTER that Kamailio sends to Asterisk, or maybe something else going wrong? Has anyone seen results like this and do you spot something here that needs fixing? Thanks, Olli

To Rewrite SDP when request goes from kamailio to outside network
by Anurag Mishra 14 Jul '14

14 Jul '14

Hi All, I have been struggling with this issue for a long and could not find a way to solve it. I have setup FreeSWITCH and Kamailio on the single server but on a private server with a private IP and fronted by firewall. Firewall has all the ports opened. FreeSWITCH is running with nonat. Kamailio has public IP advertised on port 5060 and private IP on 5070 for phones on LAN. Problem is with outbound calls there is no audio and reason I can see is contact field in SDP has the private IP of the server instead of the public IP. Internal device to device calls is working fine. I have tried to rewrite the SDP and have written below code, but got no success: request_route > { > xlog("L_DBG", "Request Route Enter"); > if (is_method("INVITE")) > { > xlog("L_DBG", "Request Route Enter in Invite"); > if (has_body("application/sdp")) > { > xlog("L_DBG", "Request Route Enter in SDP of > Invite"); > if (search("IN IP4 PRIVATE_IP")) > { > xlog("L_DBG", "Request Route Search IN IP4 > PRIVATE_IP"); > fix_nated_sdp("8", "PUBLIC_IP"); > fix_nated_sdp("2", "PUBLIC_IP"); > } > } > } > } > Can anyone help me to get rid of this. Thanks, Anurag Mishra

by Will Ferrer 11 Jul '14

11 Jul '14

Hi We would like to upgrade or debian instances to the apt repo for 4.1.4+wheezy. Is this release soon to be stable and ready for use? We would like to upgrade so we can get around the memory leak that arises when many reloads occur as described here: http://sip-router.org/tracker/index.php?do=details&task_id=436 Thank you very much for any advice any one can offer us. All the best. Will Ferrer

Update Interval for Rtimer
by AliReza Khoshgoftar Monfared 11 Jul '14

11 Jul '14

Hi, I have a basic yet weird problem with Rtimer module. I cannot make it execute a route block for me at an interval of my choice (which is what it is supposed to do, right?) Here is a simplified example with relevant parts of my config script: Assume I want to print "hello" every 100 ms: I have a script like this (I've put all my global variables, in case they matter and my relevant route blocks...) Is there anything I am doing wrong here in the usage of rtimer? *####### Global Parameters #########* > > *#!ifdef WITH_DEBUG* > *debug=4* > *log_stderror=yes* > *#!else* > *debug=-2* > *log_stderror=no* > *#!endif* > > *memdbg=5* > *memlog=5* > > *log_facility=LOG_LOCAL0* > > *fork=yes* > *children=4* > > */* comment the next line to enable TCP */* > *disable_tcp=yes* > > */* uncomment the next line to disable the auto discovery of local aliases* > * based on revers DNS on IPs (default on) */* > *auto_aliases=no* > > */* add local domain aliases */* > *# alias="mysipserver.com <http://mysipserver.com>"* > *dns=no # (cmd. line: -r)* > *rev_dns=no # (cmd. line: -R)* > > *port=5060* > > */* uncomment and configure the following line if you want Kamailio to * > * bind on a specific interface/port/proto (default bind on all > available) */* > *listen=eth0:5060* > > *sip_warning=no* > > *####### Modules Section ########* > > *#set module path* > > *#mpath="/usr/local/lib/kamailio/modules_k/:/usr/local/lib/kamailio/modules/"* > *loadpath "/usr/lib/x86_64-linux-gnu/kamailio/modules"* > > > *#loadmodule "db_mysql.so"* > *loadmodule "mi_fifo.so"* > *loadmodule "kex.so"* > *loadmodule "tm.so"* > *loadmodule "tmx.so"* > *loadmodule "sl.so"* > *loadmodule "rr.so"* > *loadmodule "pv.so"* > *loadmodule "maxfwd.so"* > *loadmodule "textops.so"* > *loadmodule "siputils.so"* > *loadmodule "xlog.so"* > *loadmodule "xprint.so"* > *loadmodule "sanity.so"* > *loadmodule "ctl.so"* > *loadmodule "mi_rpc.so"* > *loadmodule "acc.so"* > *loadmodule "dispatcher.so"* > *loadmodule "exec.so"* > *loadmodule "rtimer.so"* > *loadmodule "benchmark.so"* > > > *# ----------------- setting module-specific parameters ---------------* > > > *# ----- mi_fifo params -----* > *modparam("mi_fifo", "fifo_name", "/tmp/kamailio_fifo")* > > > *# ----- rr params -----* > *# add value to ;lr param to cope with most of the UAs* > *modparam("rr", "enable_full_lr", 1)* > *# do not append from tag to the RR (no need for this script)* > *modparam("rr", "append_fromtag", 0)* > > > *# ----- acc params -----* > *modparam("acc", "log_flag", 1)* > *modparam("acc", "failed_transaction_flag", 3)* > *modparam("acc", "log_extra", * > * > "src_user=$fU;src_domain=$fd;dst_ouser=$tU;dst_user=$rU;dst_domain=$rd;src_ip=$si")* > > *# ----- tm params -----* > *modparam("tm", "fr_timer", 2000)* > *modparam("tm", "fr_inv_timer", 40000)* > > *# ----- dispatcher params -----* > *modparam("dispatcher", "list_file", > "/home/ubuntu/Downloads/dispatcher.list")* > *modparam("dispatcher", "flags", 2)* > *modparam("dispatcher", "dst_avp", "$avp(AVP_DST)")* > *modparam("dispatcher", "grp_avp", "$avp(AVP_GRP)")* > *modparam("dispatcher", "cnt_avp", "$avp(AVP_CNT)")* > > *# ----- xlog params -----* > *modparam("xlog", "buf_size", 8192)* > *modparam("xlog", "log_facility", "LOG_LOCAL0")* > > *# ----- rtimer params -----* > *modparam("rtimer", "timer", "name=ta;interval=1;mode=1;")* > *modparam("rtimer", "exec", "timer=ta;route=8")* > > > *####### Routing Logic ########* > > > *# main request routing logic* > *route {* > * ...* > * # calls various routing blocks, but no explicit call to route("8")* *}* *route[8] {* * # to be executed on timer * * xplog("L_ALERT","hello");* *}*
