Ro_CCR function
by Shane Harrison 03 Feb '15

03 Feb '15

Hi all, In a previous post I was alerted to the (perhaps obvious) fact that that ims_charging module is design to run within an IMS environment: http://lists.sip-router.org/pipermail/sr-users/2015-January/086675.html I have subsequently attempted to modify the module to work with the standard usrloc Kamailio module. I decided to branch from the 4.2.2 release rather than the master since I was unsure of the state of the ims_charging module in the master. It now compiles fine and installs. … [View More]I also have the cdp module talking watchdog_requests to a freeDiameter server so at that level things seem OK. However inserting the Ro_CCR() call into the kamailio cfg file shows up some problems, primarily: Feb 2 01:05:52 hh-rcs-sipproxy3 /usr/sbin/kamailio[6473]: WARNING: usrloc [dlist.c:624]: register_udomain(): Registering a new domain called 'voip.we-rcs.flowcloud.systems' with usrloc Feb 2 01:05:52 hh-rcs-sipproxy3 /usr/sbin/kamailio[6473]: ERROR: <core> [db.c:443]: db_check_table_version(): invalid version 0 for table voip.we-rcs.flowcloud.systems found, expected 6 (check table structure and table "version") Exploring this error leads me to a few questions: 1) The 4.2.2 Ro_CCR() has the diameter domain as a parameter. The addition of this function to my kamailio.cfg file causes ro_fixup() -> domain_fixup() -> ul.register_domain which as per the log above, attempts to look for a table with the same name as the domain. Is it expected that such a table exists, for standard Kamailio I thought all usrloc records simply go into the Location table , regardless of the domain. 2) What is the purpose of the ro_fixup() 3) I notice that the 4.3 module documentation for ims_charging module has 6 parameters for the function call while the example code given in the same section as only 5 (missing domain). The code from the master branch for the function is different again - not sure if 4.3 is still in quite a bit of flux or not for the ims_charging module? 4) Should I be using 4.3 ims_charging module as a starting point or is 4.2.2 good enough i.e are there major changes? At this stage I am going to create a table for the domain but would like some clarity on how the usrloc and domains relate to table names.

Grouped dispatching
by Grant Bagdasarian 02 Feb '15

02 Feb '15

Hello, Would the below scenario be possible using the dispatcher module or any other routing module? Destination 1: 192.168.1.1 Destination 2: 192.168.1.2 Destination 3: 172.168.1.1 These three destinations belong to the same distribution group(set), but Kamailio has to do the following: Perform round-robin using destination 1 and 2, but if both are down fail-over to destination 3. I hope I'm being clear enough. Regards, Grant

Video Key-Frame Request using RTCP FIR or SIP INFO message
by Muhammad Shahzad 02 Feb '15

02 Feb '15

Hi, This may be a bit out of focus topic for this forum but i am posting it here anyway with hope that some guru would shed some light on it and point me to right direction. The problem is that i want to establish video call between a webrtc and a sip client using kamailio (for signalling) and RTPEngine (for media relay). Both signalling and the audio stream seems to work perfectly fine The remote video on webrtc client side (i.e. video stream from sip client) takes about 20-30 seconds to … [View More]

Async module taking down our server
by Will Ferrer 31 Jan '15

31 Jan '15

Hi All We are trying to use the async module to to delay sending a bye on from one end of the call to the other. We are using async_route(routename, seconds) to delay the WITHINDLG route. The idea is that in the future we want to be able to have our billing min duration enforced (though currently we are having issues with the dialog module that we are discussing in another thread). After running this on our deploy servers, the delays before sending on the byes get longer and longer, and then … [View More]kamailio goes down. Then the receive udp buffer fills up. We tried it with both 4 and 400 async workers, and it made no difference. I am including a screen capture of the servers stats when this happens taken from voip monitor. Here are the relevant parts of the config: ... loadmodule "async.so" ... modparam("async", "workers", ASYNC_THREADS) ... request_route { ... route(DELAYED_BYE_STATIC); ... route[DELAYED_BYE_STATIC] { xlog("L_DEBUG","route DELAYED_BYE_STATIC"); #!ifdef WITH_DELAYED_BYE_STATIC if (is_method("BYE")) { xlog("L_DEBUG","route DELAYED_BYE_STATIC, from self \n"); #if (from_uri == myself) { if ((allow_trusted() || allow_source_address()) && from_uri == myself) { xlog("L_DEBUG","route DELAYED_BYE_STATIC, Bye detected, from self \n"); send_reply("200", "OK"); xlog("L_DEBUG","route DELAYED_BYE_STATIC, sent 200 about to sleep \n"); setflag(FLT_ACC); # do accounting ... setflag(FLT_ACCFAILED); # ... even if the transaction fails if (has_totag()) { xlog("L_DEBUG","route DELAYED_BYE_STATIC, sleeping to WITHINDLG_DELAYED \n"); async_route("WITHINDLG_DELAYED", MIN_DURATION); } else { xlog("L_DEBUG","route DELAYED_BYE_STATIC, sleeping to WITHINDLG \n"); async_route("WITHINDLG", MIN_DURATION); } xlog("L_DEBUG","route DELAYED_BYE_STATIC, slept\n"); exit; } } #!endif return; } ... route[WITHINDLG_DELAYED] { xlog("L_DEBUG", "route WITHINDLG_DELAYED: triggered \n"); $avp(was_delayed) = 1; route(WITHINDLG); } ... route[WITHINDLG] { xlog("L_DEBUG", "route WITHINDLG: will -- DLG triggered, request method: $rm \n"); #!ifdef WITH_DISPATCHER if(is_method("BYE|CANCEL")) { xlog("L_DEBUG","route WITHINDLG: cancel or bye detected, request method: $rm \n"); #!ifdef WITH_DISPATCHER_LOAD_AWARE xlog("L_DEBUG","route WITHINDLG: running ds_load_update, request method: $rm \n"); ds_load_update(); #dlg_get ("$ci","$ft","$tt"); #dlg_bye ("all"); #!endif } #!endif if (has_totag() || $avp(was_delayed) == 1) { xlog("L_DEBUG", "route WITHINDLG: will -- DLG has totag or was_delayed: $avp(was_delayed) \n"); # sequential request withing a dialog should # take the path determined by record-routing if (loose_route()) { xlog("L_DEBUG", "route WITHINDLG: will -- DLG has loose route \n"); route(DLGURI); if (is_method("BYE")) { xlog("L_DEBUG","route WITHINDLG: BYE detected"); setflag(FLT_ACC); # do accounting ... setflag(FLT_ACCFAILED); # ... even if the transaction fails xlog("L_DEBUG","route WITHINDLG: ACC flag set"); } else if ( is_method("ACK") ) { # ACK is forwarded statelessy route(NATMANAGE); } else if ( is_method("NOTIFY") ) { # Add Record-Route for in-dialog NOTIFY as per RFC 6665. record_route(); } xlog("L_DEBUG", "route WITHINDLG: will -- DLG RELAY 1\n"); route(RELAY); } else { xlog("L_DEBUG", "route WITHINDLG: will -- DLG else \n"); if (is_method("SUBSCRIBE") && uri == myself) { # in-dialog subscribe requests route(PRESENCE); exit; } if ( is_method("ACK") ) { xlog("L_DEBUG", "route WITHINDLG: will -- DLG is ack \n"); if ( t_check_trans() ) { xlog("L_DEBUG", "route WITHINDLG: will -- DLG t_check_trans \n"); # no loose-route, but stateful ACK; # must be an ACK after a 487 # or e.g. 404 from upstream server xlog("L_DEBUG", "route WITHINDLG: will -- DLG RELAY 2\n"); route(RELAY); exit; } else { # ACK without matching transaction ... ignore and discard exit; } } sl_send_reply("404","Not here"); } exit; } } ... Does any one know if this is a bug or a leak with in the async module, or perhaps something I am doing in my config? Thanks in advance for an assistance you can offer me. All the best.

Wrong location entries when using usrloc with Mongo
by Mickael Marrache 30 Jan '15

30 Jan '15

Hi, I start with no location nor in Mongo, nor in memory. My UA registers successfully and I can see the location entry in Mongo. Then, I close my UA which unregisters (by setting Expires header to 0). Then, I open the app again and a new registration is made. The entry after first registration. Looks okay. { "_id" : ObjectId("54cb38f684e58133783f2b42"), "username" : "A", "contact" : "sip:A@192.168.1.3:54217;rinstance=DFAEBBC7;transport=tcp", "expires" : ISODate("2015-01-30T08:55:… [View More]34Z"), "q" : -1, "callid" : "297EC55073A07BF78F0C05822A6CCDFB47E48705", "cseq" : 8809, "flags" : 0, "cflags" : 0, "user_agent" : "Acrobits Softphone Business/3.1", "received" : "sip:XXXXXXXXXXX:54217;transport=tcp", "path" : "<sip:XXXXXXXXXX;lr;received=sip:XXXXXXXXXXX:54217%3Btransport%3Dtcp>", "socket" : "udp:XXXXXXXXX:5060", "methods" : 4751, "last_modified" : ISODate("2015-01-30T07:55:34Z"), "ruid" : "uloc-54cb38df-3378-2", "instance" : null, "reg_id" : 0 } The same entry after un register (Expires 0). Note that the username field is missing. In any case, I expected the entry to be deleted. { "_id" : ObjectId("54cb38f684e58133783f2b42"), "expires" : ISODate("2015-01-30T08:56:51Z"), "q" : -1, "cseq" : 8811, "flags" : 0, "cflags" : 0, "user_agent" : "Acrobits Softphone Business/3.1", "received" : "sip: XXXXXXXXX:54217;transport=tcp", "path" : "<sip: XXXXXXXXX;lr;received=sip: XXXXXXXXX:54217%3Btransport%3Dtcp>", "socket" : "udp: XXXXXXXXX:5060", "methods" : 4751, "last_modified" : ISODate("2015-01-30T07:56:51Z"), "callid" : "297EC55073A07BF78F0C05822A6CCDFB47E48705", "instance" : null, "reg_id" : 0, "contact" : "sip:A@192.168.1.3:54217;rinstance=DFAEBBC7;transport=tcp" } The entries after second registration. The new entry looks okay. But, the old entry is still here. { "_id" : ObjectId("54cb38f684e58133783f2b42"), "expires" : ISODate("2015-01-30T08:56:51Z"), "q" : -1, "cseq" : 8811, "flags" : 0, "cflags" : 0, "user_agent" : "Acrobits Softphone Business/3.1", "received" : "sip: XXXXXXXXX:54217;transport=tcp", "path" : "<sip: XXXXXXXXX;lr;received=sip: XXXXXXXXX:54217%3Btransport%3Dtcp>", "socket" : "udp: XXXXXXXXX:5060", "methods" : 4751, "last_modified" : ISODate("2015-01-30T07:56:51Z"), "callid" : "297EC55073A07BF78F0C05822A6CCDFB47E48705", "instance" : null, "reg_id" : 0, "contact" : "sip:A@192.168.1.3:54217;rinstance=DFAEBBC7;transport=tcp" } { "_id" : ObjectId("54cb3a7884e581337a25b895"), "username" : "A", "contact" : "sip:A@192.168.1.3:54217;rinstance=DFAEBBC7;transport=tcp", "expires" : ISODate("2015-01-30T09:02:00Z"), "q" : -1, "callid" : "297EC55073A07BF78F0C05822A6CCDFB47E48705", "cseq" : 8813, "flags" : 0, "cflags" : 0, "user_agent" : "Acrobits Softphone Business/3.1", "received" : "sip: XXXXXXXXX:54217;transport=tcp", "path" : "<sip: XXXXXXXXX;lr;received=sip: XXXXXXXXX:54217%3Btransport%3Dtcp>", "socket" : "udp: XXXXXXXXX:5060", "methods" : 4751, "last_modified" : ISODate("2015-01-30T08:02:00Z"), "ruid" : "uloc-54cb38df-337a-1", "instance" : null, "reg_id" : 0 } The issue is the entry is not deleted after un registering. I precise that registrations are dispatched over multiple registrars with all accesses the same Mongo cluster. Thanks, Mickael [View Less]
