One sided or no voice issue with websockets
by Kamrul Khan 21 Oct '14

21 Oct '14

Hi, We have a setup with sipml5 to kamailio. It works perfectly within local network. In public network the signaling establishes perfectly, but most of the time we hear no voice, sometimes we hear one sided voice and in rare cases we hear voice from both sides. To fix this issue we configured our nathandler like the below: But, still no luck. Any idea how to fix this? Please HELP!!! modparam("nathelper|registrar", "received_avp", "$avp(RECEIVED)") modparam("nathelper", "nortpproxy_str", "a=sdpmangled:yes\r\n") . . . route { . . if (nat_uac_test("115")) { if(nat_uac_test("64")) force_rport(); } if (method=="REGISTER") { fix_nated_register(); add_rcv_param(); } else { fix_nated_contact(); if(nat_uac_test("64")){ if (!add_contact_alias()) { xlog("L_ERR", "Error aliasing contact <$ct>\n"); sl_send_reply("400", "Bad Request"); exit; } } else { add_rcv_param(); } } } . . onreply_route { if (nat_uac_test(64)) { add_contact_alias(); } . . }

MSILO module not delivering messages
by aawaise 21 Oct '14

21 Oct '14

I have tried to add msilo module to my kamailio.cfg using the link http://sip-router.1086192.n5.nabble.com/Msilo-not-delivering-message-status… Problem is that messages from a user are received on the server. And they can be seen using siremis. But they are not forwarded when the intended receiver gets online. I have added the outboud_proxy in modparameters of MSILO module #!ifdef WITH_MSILO modparam("msilo", "db_url", "mysql://openser:5mil5My5ql@192.168.1.20/openser") modparam("msilo", "from_address", "sip:$rU@mydomain") modparam("msilo", "contact_hdr", "Contact:<sip:$rU@mydomain>\r\n") modparam("msilo", "content_type_hdr", "Content-Type:text/plain\r\n") modparam("msilo", "offline_message", "User $rU is offline!") modparam ("msilo", "outbound_proxy", "sip:mydomain:6524;transport=tcp") modparam ("msilo", "outbound_proxy", "sip:mydomain") modparam("msilo", "expire_time", 604800) #!endif I have added the code available on the link to my kamailio.cfg. -- View this message in context: http://sip-router.1086192.n5.nabble.com/MSILO-module-not-delivering-message… Sent from the Users mailing list archive at Nabble.com.

Handle "MESSAGE" packet
by aawaise 21 Oct '14

21 Oct '14

I want to know how kamailio server handles incoming MESSAGE packets of SIP format ? If a sender sends a MESSAGE packet for receiver, and receiver is offline, how will server handle the packet. Can it hold the packet until the receiver is online and then deliver to receiver ?? -- View this message in context: http://sip-router.1086192.n5.nabble.com/Handle-MESSAGE-packet-tp131509.html Sent from the Users mailing list archive at Nabble.com.

Re: [SR-Users] kamailio 4.2 ，have some problems when use mysql db

Are you using 4.1 or 4.2? Because the subject mentioned 4.2 but the version of kamailio is 4.1 Daniel On 20/10/14 11:39, 张顺通 wrote: > -M 12 can not help. all config is same. > > see ka.log in attachment, kamailio version is 4.1.6 > > version: kamailio 4.1.6 (x86_64/linux) 010d57 > > flags: STATS: Off, USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS, > DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, > DBG_QM_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, > USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES > > ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, > MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 4MB > > poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. > > id: 010d57 > > compiled on 16:48:03 Oct 20 2014 with gcc 4.1.2 > > -- Daniel-Constantin Mierla http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda

by Vik Killa 20 Oct '14

20 Oct '14

Hello, I've installed kamailio from debian repo: deb http://deb.kamailio.org/kamailio wheezy main deb-src http://deb.kamailio.org/kamailio wheezy main I am unable to use any RPC related module though... apt-cache search doesn't show them...I installed every kamailio-* package just to make sure but still no luck. Basically, i just want to reload a hash remotely Locally I can do this with: kamcmd htable.dump freeswitch_ips Do I need to compile/install kamailio from source in order to use an RPC package? Thanks. /V

parallel forking
by Yuriy Gorlichenko 20 Oct '14

20 Oct '14

Hello. I try to do parallel fork calls to endpoints that have same username and different destination URI. Logic of my script: checking location table for rows with needed account get info from contact at loop for every step check technology (sip or ws) append_branch with existing destination for this account rewrite packet with rtpengine to needed technology forward packets via t_relay sql_query("ca", "select contact from location where username='$tU'", "ra"); xlog("rows: $dbr(ra=>rows) cols: $dbr(ra=>cols)\n"); if($dbr(ra=>rows)>0){ $var(i)=0; while($var(i)<$dbr(ra=>rows)){ xlog("L_INFO","SQL query return contact {$dbr(ra=>[$var(i),0])} for {$tU} at step {$var(i)}\n"); if ($dbr(ra=>[$var(i),0])=~"transport=ws"){ xlog("L_INFO", "This is a Websocket call to endpoint"); sql_pvquery("ca", "select received from location where contact='$dbr(ra=>[$var(i),0])'","$var(recieved)"); xlog("L_INFO","SQL query return recieved {$var(recieved)} for {$tU}\n"); $du=$var(recieved); xlog("L_INFO", "Request going FROM ASTERISK to WS. Destination is {$du}\n"); xlog("L_INFO","Websocket Destination URI is {$var(recieved)} for {$tU}\n"); rtpproxy_manage("froc+SP"); t_on_reply("REPLY_FROM_WS"); append_branch("sip:$tU@$du"); $var(i) = $var(i) + 1; } else { xlog("L_INFO", "This is a classic UDP call to endpoint"); $du="sip:"+$(dbr(ra=>[$var(i),0]){s.select,1,@}); xlog("L_INFO","Classic Destination URI is {$dbr(ra=>[$var(i),0])} for {$tU}\n"); rtpproxy_manage("co"); t_on_reply("MANAGE_CLASSIC_REPLY"); append_branch("sip:$tU@$du"); $var(i) = $var(i) + 1; } #append_branch("sip:$tU@$du"); } } return 1; So it customised schema of standart example seturi("sip:a@example.com"); append_branch("sip:b@example.com"); append_branch("sip:c@example.com"); append_branch("sip:d@example.com"); t_relay(); At my test I have 2 endpoints with WS and UDP phones (at fist step ir WS and 2 step it UDP). when I do these steps (at my script) I see packet at TCP dump and saw that sended only one packet to UDP but body of packet is WS. Then I saw log of kamailio. I see that at second step packet changed body to WS body (so strange because other steps before and after goes for UDP (as at logic of script)) What I need to do for send parallel INVITES to multiple endpoints correctly? Thanks
