Rtpproxy ptime in ringing inject
by Grygoriy Dobrovolskyy 19 May '14

19 May '14

Hello list, a long time ago i have build and application which injects ringing from rtpproxy to the client, while i am trying to reach his destination. The commande looks like this (log) May 19 10:17:44 rtpproxy[2529]: DBUG:handle_command: received command "29304_278705 P-1 B2B.256.470174 /usr/local/src/rtpproxy/sounds/ring session d20fbd749deed7e1f54460af276dee6d-0ead;1 " May 19 10:17:44 rtpproxy[2529]: INFO:handle_play: -1 times playing prompt /usr/local/src/rtpproxy/sounds/ring codec 8 May 19 10:17:44 rtpproxy[2529]: DBUG:doreply: sending reply "29304_278705 0#012" Everything works fine, a long time ago i have modded the rtpproxy a bit so when he sends the audio, he sends it with 20ms ptime instead of default 10ms, and i have totally forgot where is that part, i am digging into sources and not able to find it. Dear list if somebody remembers where is this damn setting in sources, i would be glad to hear from you. Thank you

mtree reload commands don't remove items from memory
by Juha Heinanen 18 May '14

18 May '14

i started to wonder why routing was sometimes wrong in my proxy and after studying the issue, i came to the conclusion that mtree reload commands (mi or rpc) don't remove entries from memory when they are removed from database. i started my proxy with empty mtrees db table (and empty memory table): # sip-proxy_ctl mi mt_summary MT:: TNAME=lp_out TTYPE=0 MEMSIZE=0 NRNODES=0 NRITEMS=0 RELOADCOUNT=0 RELOADTIME=1400419785 then i added one entry to db table and gave reload command. after that one entry correctly showed up in memory table: # sip-proxy_ctl mi mt_summary MT:: TNAME=lp_out TTYPE=0 MEMSIZE=1636 NRNODES=6 NRITEMS=1 RELOADCOUNT=1 RELOADTIME=1400419817 then i deleted the only entry from db, verified with phpmyadmin that the table really was empty, and gave again reload command. that command didn't have any effect in memory table: # sip-proxy_ctl mi mt_summary MT:: TNAME=lp_out TTYPE=0 MEMSIZE=1636 NRNODES=6 NRITEMS=1 RELOADCOUNT=1 RELOADTIME=1400419817 not even reload count got incremented. after that i went and added some debug to rpc_mtree_reload function and got this: May 18 16:30:17 siika /usr/sbin/sip-proxy[26536]: INFO: mtree [mtree_mod.c:1169]: rpc_mtree_reload(): reloading from db 'lp_out' the info is here: LM_INFO("reloading from db '%.*s'\n", pt->tname.len, pt->tname.s); if(mt_load_db(pt)!=0) { LM_ERR("cannot re-load mtree from database\n"); goto error; } my conclusion is that mt_load_db() function is somehow broken. -- juha

gateway connection
by Joli Martinez 18 May '14

Hello, I have setup Kamailio with Freeswitch and it is working. Right now I have my SIP providers connected to Freeswitch. Would it make sense to connect my SIP providers to kamailio instead. My setup will be intended to resell minutes. If so what advantages will I gain by connecting my SIP providers to kamailio

fetch bindings- timeout
by Daniel Ciprus 16 May '14

16 May '14

All, According to RFC3261: 10.2.3<http://tools.ietf.org/html/rfc3261#section-10.2.3> Fetching Bindings A success response to any REGISTER request contains the complete list of existing bindings, regardless of whether the request contained a Contact header field. If no Contact header field is present in a REGISTER request, the list of bindings is left unchanged. We should be able to fetch bindings from registrar. With my very limited knowledge of kamailio code (dialog-ng/dlg-handlers.c) : if ((!msg->cseq && (parse_headers(msg, HDR_CSEQ_F, 0) < 0 || !msg->cseq)) || !msg->cseq->parsed) { LM_ERR("bad sip message or missing CSeq hdr :-/\n"); goto error0; } This condition should also have something like: msg->method != "REGISTER" otherwise it's throwing errors and I'm not getting any response back from kamailio. Request just times out. Can somebody confirm that this feature is/is not implemented ? thank you Dan. Here is snippet of sipp xml scenario which I'm using to fetch bindings: <scenario name="FetchBindings"> <label id="1"/> <send> <![CDATA[ REGISTER sip:[field2] SIP/2.0 Via: SIP/2.0/[transport] [local_ip]:[local_port];rport;branch=[branch] From: <sip:[field0]@[field2]>;tag=aabbcc To: <sip:[field0]@[field2]> Call-ID: [call_id] CSeq: [cseq] REGISTER Max-Forwards: 70 Allow: INVITE, ACK, CANCEL, BYE, MESSAGE, OPTIONS, NOTIFY, PRACK, UPDATE, REFER User-Agent: IM-client/OMA1.0 sipp-script P-Access-Network-Info: ADSL;utran-cell-id-3gpp=00000000 Privacy: none P-Visited-Network-ID: [field2] Supported: path Content-Length: 0 ]]> </send> <recv response="200" timeout="10000"/> </scenario> -- Daniel Ciprus Integration engineer http://www.acision.com 9954 Mayland Dr Suite 3100 Richmond, VA 23233 USA T: +1 804 762 5601 E: daniel.ciprus(a)acision.com<mailto:daniel.ciprus@acision.com> ________________________________ This e-mail and any attachment is for authorised use by the intended recipient(s) only.

Just 80 call/second
by Andrea Meroni 16 May '14

16 May '14

Hi all, i have some strange performance issues (with Kamailio config file i guess): using the default configuration file i can reach a 500 call/s rate, while using the default configuration file in the dispatcher folder i can reach just a 80 call/s rate (using the dispatching failover algorithm ...). The dispatcher is in front on a very basic Kamailio-based IMS core. Something has some hint about this issues? Andrea

Dispatcher poor performance
by Andrea Meroni 16 May '14

16 May '14

Hi all, i have a strange performance problem: i placed a dispatcher in front of a bundle of Kamailio proxies and, even with a really simple dispatching logic route { #ds_select_dstl("1", "2"); $du="sip:192.168.100.51:5060"; forward(); } that actually doesn't even use the dispatcher module i get that when the server's (192.168.100.51) CPU is 100% used the dispatcher's CPU is ~50% used. Using the dispatching algorithm based on the hash of the From-URI or the failover one (that should be the lightest dispatching algorithm, computationally speaking ...) the performance are almost the same. So, since i saw that in the documentation that the dispatcher module is designed to be "suitable for handling heavy SIP traffic", my question is: what i misconfigured? In my opinion it seems weird that the dispatcher module is able to manage just (as my tests suggest) just 2 Kamailio SIP proxies ... Andrea

HI Alex, Thanks for the suggestion. I tried using the function sl_send_reply(msg, 403, "Forbidden") in the receive.c file after including the header files. But the following error is coming when compiling the kamailio. CC (gcc) [kamailio] receive.o receive.c: In function âsend_denialâ: receive.c:375: warning: implicit declaration of function âsl_send_replyâ LD (gcc) [kamailio] kamailio receive.o: In function `send_denial': /home/varun/EP1.0/kamailio-4.1.3_src/kamailio-4.1.3/receive.c:375: undefined reference to `sl_send_reply' collect2: ld returned 1 exit status make: *** [kamailio] Error 1 Please suggest any solution to this problem. So I have make some changes in the Makefile as it seems to be linking problem. Thanks in advance.
