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

I don't know how to apply the global flag in Kamailio. Can you give me an example? -H From: Daniel-Constantin Mierla <miconda(a)gmail.com> Reply-To: <miconda(a)gmail.com>, "Kamailio (SER) - Users Mailing List" <sr-users(a)lists.sip-router.org> Date: Thursday, 3 July, 2014 1:47 AM To: "Kamailio (SER) - Users Mailing List" <sr-users(a)lists.sip-router.org> Subject: Re: [SR-Users] how to remove non-digits using dp_translate Hello, you have to replace [^0-9] with empty, using the global flag.

Is there any compelling reason to use textops' cmp_str()/cmp_istr() versus the 'eq' operator (or the implicit string comparison in "a" == "b")? -- Alex Balashov - Principal Evariste Systems LLC Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/ Please be kind to the English language: http://www.entrepreneur.com/article/232906

by Will Ferrer 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");* *}*

INVITE to 200, INVITE to 404, INVITE to 487
by Luis F Urrea 11 Jul '14

11 Jul '14

Hi all, I have seen Siremis charts that account stats such as INVITE to 200 and INVITE to 404. I would like to have this sort of accounting but without the use of the Siremis UI, so I am wondering how is this achieved, is this done through the ACC module and correlating responses? TIA

Path attribute not updated in location table when user switches between two access points behind NAT
by Prasun Bheri 11 Jul '14

11 Jul '14

Hi Group, I stumbled upon a possible bug in Kamailios (4.0.0) Path module. Setup: Proxy server is behind another Kamailio Load Balancer and both (Proxy & LB) are configured to use Path module. When client registers for the first time path is inserted into Location table successfully however when client switches from currently Access Point to another AP (which are both behind a NAT), Path attribute in Location table is not updated with newer <ip>:<port> When client switched from one AP to another, IP remained same however port changed from 48238 to 33038 and subsequent update query issued by Kamailio is as follows: update location set expires='2014-07-11 19:27:32',q=-1.00 ,cseq=1805331004,flags=0,cflags=64,user_agent='xxxxxxxxxx',received='sip:xx5.xx1.xx1.219: *33038*;transport=tcp',path='<sip:xx3.xx1.xx9.53;transport=tcp;lr;received=\'sip:xx5.xx1.xx1.219:33038;transport=tcp\'>',socket='tcp:xx3.xx1.xx9.28:5060',methods=16351,last_modified='2014-07-11 18:27:32',ruid='uloc-53bf7f9c-4254-e',instance='<urn:imei:911304251588897>',reg_id=1 where username='testuser' *AND **contact='sip:testuser@xx5.xx1.xx1.219:33038;transport=tcp' *AND callid='7983ce39-2ffd3a92-8f82f477-e6313128-84b64128' AND domain=' vvoip.xxxxxxxx.com' In the where clause contact should have been old value taken from initial registration, however contact from new registration is used, so where condition always fails and entry is never updated. as a result no further calls or messages could be received by the client. is there any workaround for this issue? PS: Here is the configuration of path module. # set path to lazy mode modparam("registrar", "path_mode", 1) # set to 1 to use path header modparam("registrar", "use_path", 1) # set to 1 to use path received parameter modparam("registrar", "path_use_received", 1) modparam("path", "use_received", 1) Thanks & Regards, Prasun

Hi, I am trying to upgrade from mediaproxy-ng to rtpengine trunk version. The compilation steps go well and i have deb packages created. However when i try to install them (on same machine where they compiled), i get this error for every deb package, ngcp-rtpengine-daemon pre-depends on ngcp-system-tools * ngcp-system-tools is not installed.* I can't find this ngcp-system-tools package anywhere, neither on source nor in built deb packages. So, i am stuck. Can anyone help? Thank you.

Listen to to 2 NIC's IP addresses and establish call between
by Raj Roy Ghandhi 10 Jul '14

10 Jul '14

Hi Friends, I have to configure a Kamailio in to meet following requirements 1. PC having 2 NICs (NIC-A and NIC-B) with 2 different IPs (IP-A and IP-B) from 2 different service providers. Totally 2 different IPs. NIC-A attached to provider is a private SIP traffic provider and having IP-A. (no internet access) NIC-B attached to internet service provider and having IP-B. 2. I get SIP traffic to IP-A of NIC-A from SIP traffic provider. 3. I need to forward that SIP traffic to another SIP carrier in remote location using IP-B of NIC-B through internet and have the call establish without any issue. How can I achieve this with single instance of Kamailio running on same machine. Please advice me. Best Regards, Roy.
