SIP Trunks
by Keith 09 Oct '13

09 Oct '13

Hi, Can anyone point me in the right direction for setting up SIP trunks? Whenever I send a call to a registered user on a trunk it just sends to destination s(a)x.x.x.x. Is there anyway to say "these extensions are location at this destination IP and port". Cheers, Keith

Sometimes cr_route fails on old kamailio 1.4
by mayamatakeshi 09 Oct '13

09 Oct '13

Hello, I have to take care of an old server running kamailio 1.4 (I plan to upgrade to latest, but I cannot do it at the moment). It uses carrierroute and it works fine. Now I am testing adding a new carrier and it worked. However, sometimes I get a failure to resolve a route (using cr_route): Oct 9 21:29:04 centos53-02121 /usr/local/src/svn/kamailio-1.4/kamailio[3160]: ERROR:carrierroute:cr_do_route: desired routing domain doesn't exist, prefix 99900000112233445566778899, carrier 10, domain 0 … [View More] I can see the cause of the problem is because an element called "id" is solved differently sometimes when "cr_reload_routes" is issued. I am using always this same table: mysql> select * from carrierroute where carrier=10; +------+---------+--------+-------------+-------+------+------+-------+--------------------+----------------+----------------+-------------+ | id | carrier | domain | scan_prefix | flags | mask | prob | strip | rewrite_host | rewrite_prefix | rewrite_suffix | description | +------+---------+--------+-------------+-------+------+------+-------+--------------------+----------------+----------------+-------------+ | 4271 | 10 | 0 | 999000 | 0 | 0 | 1 | 6 | 192.168.2.123:5060 | | | NULL | | 4272 | 10 | 1 | 999000 | 0 | 0 | 1 | 6 | 192.168.2.123:5060 | | | NULL | +------+---------+--------+-------------+-------+------+------+-------+--------------------+----------------+----------------+-------------+ 2 rows in set (0.00 sec) When cr_route works fine, the reload logged this: Oct 9 21:31:21 centos53-02121 /usr/local/src/svn/kamailio-1.4/kamailio[7902]: DBG:carrierroute:get_route_tree_by_id: tree carrier_10, domain 0 : 0 Oct 9 21:31:21 centos53-02121 /usr/local/src/svn/kamailio-1.4/kamailio[7902]: DBG:carrierroute:get_route_tree_by_id: tree carrier_10, domain 1 : 1 But when it fails, it logged this: Oct 9 21:29:04 centos53-02121 /usr/local/src/svn/kamailio-1.4/kamailio[3160]: DBG:carrierroute:get_route_tree_by_id: tree carrier_10, domain 0 : 1 Oct 9 21:29:04 centos53-02121 /usr/local/src/svn/kamailio-1.4/kamailio[3160]: DBG:carrierroute:get_route_tree_by_id: tree carrier_10, domain 1 : 2 So I understand that the problem is a mismatch between a value that is produced by kamailio when I ask for a domain (named '0' and '1') and value of id that probably was computed based on domain at the time the route_tree was created. So, I was thinking, maybe domain names '0' and '1' would not be good for this and I should use some longer names. Well i should not expect a domain named '0' to always result in an id=0. But I would expect that whatever id is resolved, it should happen equally for both values being matched that came from the same base element (supposedly, the domain name). I will test using longer names anyway, but since this problem doesn't happen everytime I do cr_reload_routes, I was hoping to get an opinion about it. Regards, Takeshi [View Less]

Re: [SR-Users] Presence: Duplicate entry 'username-domain-presence-*#-OFFLINE-#*' for key 'presentity_idx' when multiple clients register using the same credentials
by Yufei Tao 09 Oct '13

Thank you Juha for your replies! >From RFC3856: A Presence Event Package for the Session Initiation Protocol (SIP) 6.11. State Agents RFC 3265 [2] requires each package to consider the role of state agents in the package, and if they are used, to specify how authentication and authorization are done. State agents are core to this package. Whenever the PA is not co-located with the PUA for the presentity, the PA is acting as a state agent. It collects presence state … [View More]from the PUA, and aggregates it into a presence document. Because there can be multiple PUA, a centralized state agent is needed to perform this aggregation. That is why state agents are fundamental to presence. Indeed, they have a specific term that describes them - a presence server. Seems the presence server needs to aggregate statuses from different PUAs for the same presentity into a single presence document, if I understand it correctly? Anyway it is not what happens currently with Kamailio 4.0.3 unless I'm missing anything.

Just wondering if this is something that *should* > be done to cope with the situation where multiple presentities use the > same credentials. before knowing how to answer to that, i would like to know what presence rfcs say about this situation, i.e., is current kamailio presence implementation somehow broken when an aor (= presentity) has several active contacts. should notify give status of both contacts separately or should presence server try somehow to combine status of the contacts into a single notify? what does it mean if one contact tells that it is offline and another online? should presence server send only one notify telling that the presentity is online (since it is if one contact tells so)? -- juha On 05/10/13 11:00, sr-users-request(a)lists.sip-router.org<mailto:sr-users-request@lists.sip-router.org> wrote: Hi I use kamailio 4.0.3 with presence.

Because presentity table has a 'CONSTRAINT presentity_idx UNIQUE (username, domain, event, etag)', this gives the errors. Should the constraint be removed to cope with this situation? Thank you!

Scripting - Adding custom code

Hi, Wonder if anyone can point me in the right direction, or explain a bit more about how the code in Kamailio works. I am looking to build a front end to Kamailio so I can easily add routes etc without direct access to the config. Thanks, Keith

Hi there, I have certain queries regarding batch SUBSCRIBE and NOTIFY. I have a user who has 100 buddies in his buddy list. If any of his buddy changes his/her presence status, that user gets a NOTIFY message with presence status of all the 100 buddies. In that case, the message size is exceeding 500 KB. Thats quite a higher value for a UDP packet. Can anybody suggest- 1. If there is any way to restrict the size of the packet. 2. How to ensure that the packet is received … [View More]
