I set cfg like this: tls_port_no=9004 listen=bond0:9002 but result is: udp: 10.232.98.23 [10.232.98.23]:9002 tcp: 10.232.98.23 [10.232.98.23]:9002 tls: 10.232.98.23 [10.232.98.23]:9003

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("2015-01-30T08:55:34Z"), "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

Can kamailio generate a PRACK
by Rahul MathuR 30 Jan '15

30 Jan '15

Hello, I was wondering whether Kamailio (as proxy) can generate a PRACK on its own ( since one of the custom written dialer is not sending PRACK) ? Is there any way I can achieve this ? -- Warm Regds. MathuRahul

Does forking impact max_inv_lifetime?
by Alex Balashov 30 Jan '15

30 Jan '15

Hi, In this serial forking-based failover scenario UAC --> Proxy --> UAS 1 UAS 2 ... UAS 3 I've got a requirement to terminate the call and return an error to the UAC if there is no final response within 60 seconds. The usual fr_inv_timer / restart_fr_on_each_reply combination won't do, because even when restart_fr_on_each_reply == 0, the timer is still restarted on provisional replies of increasing response code value (e.g. 183 after 180). As the documentation states, fr_inv_timer is a branch-level construct anyway, so this approach doesn't make sense here. That's why I looked into max_inv_lifetime. However, when I set it to 60000, I still get the same result, but only when there are new branches being formed on the proxy -> UAS side. It works fine if there is no forking and a single gateway does not provide a final reply within 60 seconds. So, my sense is that the max_inv_lifetime timeout is reset when a new branch is created to UAS 2...UAS N. Is this accurate?

gruu within dialog
by samuel 29 Jan '15

29 Jan '15

Hi all, I'm having some issues treating requests within dialogs with gruu enabled with kamailio 4.1.2. I've got the "standard" configuration of WITHIN route with the adition of the next lines: if(is_gruu()){ route(LOCATION); }; before the the RELAY route call in the loose_route section. The "problem" is that the ACK with a pub-gruu on the Req-URI is not properly lookup. In the logs I can see the following statements: 2(4232) DEBUG: registrar [lookup.c:123]: lookup(): looking up pub gruu [urn:uuid:d63b1c4f-d7dc-4f4e-87f1-948123266dc0] 2(4232) DEBUG: registrar [lookup.c:158]: lookup(): 'sam(a)A.B.C.D' Not found in usrloc Where A.B.C.D is the local IP of the UA. Looking at the code, this last line looks like is looking for the "standard" URI (username@domain) instead of using the pub gruu. Am I right with this assumption or am I missing something from the code? As far as I could look, it looks like there's an exit -1 statement in the line 158 of lookup.c which disables the following gruu treatment. Since the username with IP is not registered, this ACK is lost and the sesion is not stablished (lost ACK). Can anyone provide some hints why is this failing? Thanks a lot in advance! Samuel.

Dialog module is crashing after setting track_cseq_updates to 1
by Fernando Aquilino 29 Jan '15

29 Jan '15

Hi, after setting track_cseq_updates to 1 in module dialog (and calling dlg_manage() from request_route) I'm getting reproducible crashes in both stable (4.2.2) and dev (4.3.0-dev3, 2015-01-28) releases. I made the change to cope with CSeq not being incremented when sending another INVITE with authentication information with by calling uac_auth()/append_branch()/t_relay(). The SIP trunk on the asterisk server I'm forwarding the request to requires so and sends me an "401 Unauthorized" message after the first INVITE. Anyone using it would help me with the configuration? Should I post to the dev list?

Issue with non static values for sleep in the Async module
by Will Ferrer 28 Jan '15

28 Jan '15

Hi I am having an issue with the Async module. The async_route function doesn't seem able to take a dynamic value as is it's duration. The module docs states: The sleep parameter represent the number of seconds to suspend the processing of a SIP request. Maximum value is 100. The parameter can be a static integer or a variable holding an integer. Docs here: http://kamailio.org/docs/modules/4.2.x/modules/async.html#async.f.async_rou… However when I try: async_route("WITHINDLG_DELAYED", $avp(buffer_duration) ); I get the following error when trying to restart kamailio: parse error in config file /etc/kamailio/switchsoftk amailio/includes/deployments/develop/callprocessing/../../../default.cfg, line 866, column 41-61: function async_route: parameter 2 is not constant ... failed! I also tried with $var instead of an AVP, and even tried having perl call the function (since we have gotten around this sort of limitation in the past using perl). Perl gives: Jan 24 03:27:07 develop-callprocessing /usr/sbin/kamailio[1424]: ERROR: app_perl [kamailioxs.xs:289]: moduleFunc(): Module function 'async_route' is unsafe. Call is refused. Jan 24 03:27:07 develop-callprocessing /usr/sbin/kamailio[1424]: ERROR: app_perl [kamailioxs.xs:986]: XS_Kamailio__Message_moduleFunction(): calling module function 'async_route' failed. Missing loadmodule? I have gotten around this issue with a large if else structure like the following: if ($avp(buffer_duration) == 1) { async_route("WITHINDLG_DELAYED", 1); } else if ($avp(buffer_duration) == 2) { async_route("WITHINDLG_DELAYED", 2); ......... This is messy but works for us. The bug is not blocking our progress due to this work around but I wanted to post it any way incase it helps improve the module. All the best. Will Ferrer Switchsoft
