Re: [Kamailio-Users] nested redirect
by Daniel-Constantin Mierla 05 Oct '08

Hello, your main route block is something loke: route { if(is_method("INVITE")) { .... } exit; } So, apart of INVITE, every other sip request is dropped. See default config file to get a better understanding. kamailio/openser discards by default any sip request received if there is no action to forward for it.

[Serusers] LCR module and CANCEL
by Deepak 04 Oct '08

04 Oct '08

Hi, I have the following issue: I am using lcr module to select a gw from a set of gw's based upon R-URI prefixes. All is working fine. The issue is with a CANCEL that is sent by the UAC that originates the call before a dialog can be established. This implies that the CANCEL cannot be routed to the correct GW since SER see a CANCEL and simply returns "487 request terminated". How can I forward the CANCEL to the GW the the original INVITE was forwarded to? Any help appreciated.....

[Kamailio-Users] Presence Server returns a 404 Not here msg
by Yoo Chan Jeon 03 Oct '08

03 Oct '08

Hi, I setup the presence server. My sip phone sends a PUBLISH msg. Th presence server sends a 200 msg. My another sip phone sends a SUBSCRIBE msg. The presence server returns 202 msg, and NOTIFY msg. These msgs does not include user in the contact header My sip phone sends a 200 msg I sends a second SUBSCRIBE msg to refresh it. This time my subscribe msg does not include the user in the request msg because the presence server did not include the user in the contact header. The presence server replied back with a 404 messge. So I looked at the codes, and add the user in the contact header when the presence server replys back to a client. But I stll have a same 404 msg. Do I miss something? I always appreciate your help. Thanks. Jeon

I have looked for this inside the kamctl and I don't find it, I don't believe that it was that the export error, somebody that has installed sermyadmin in suse 11? regards .. rickygm Wednesday, October 1, 2008 12:24:06 PM, Iñaki Baz Castillo wrote: Subject: Re: [Kamailio-Users] sermyadmin setup suse 11 Please, don't send an image attachment, just copy the console output. This error is very common and is related to "phplib" field. Modify /etc/openserctl and set it to "no" (or something similar..). Look for the exact error in Google for more responses. --

[Kamailio-Users] registrar module enhancements
by Daniel-Constantin Mierla 02 Oct '08

02 Oct '08

Hello, in the last time several enhancements were added to registrar module to help in dealing with user location records. This correlated with the new modue pv shall give lot of control over the destination set for calls. To get the latest devel version, check out the latest svn - svn co https://openser.svn.sourceforge.net/svnroot/openser/trunk kamailio The news in registrar module are: - ability to unregister all contacts for a SIP addres - there is a new function: unregister(table, uri) - ability to store and maintain single contact per user - the save() function accepts a new value for flags parameter (0x04) to restrict to one single record in location table - ability to access the attributes of all contacts for a user - there are two new functions: reg_fetch_contacts(table, uri, profile) and reg_free_contacts(profile) to make available/release the contacts for a SIP uri. After fetching the contacts, the attributes can be accessed via pseudo variable $ulc(profile=>attr) For more details see the README: http://www.kamailio.org/docs/modules/devel/registrar.html Here are couple of use cases: 1) only one contact per user save("location", "0x04"); Note that if you have couple of phones registering for same user, the one that sent last REGISTER message will be the only ringing. 2) check if a user is calling from a registered device and if not, deny the call if(!reg_fetch_contacts("location", "$fu", "caller")) { sl_send_reply("403", "Please register first"); exit; } $var(i) = 0; $var(found) = 0; $var(contact) = $(ct{nameaddr.uri}); while($var(found) == 0 && $var(i) < $(ulc(caller=>count))) { $if($var(contact)==$(ulc(caller=>addr)[$var(i)])) $var(found) = 1; else $var(i) = $var(i) + 1; } if($var(found) == 0) { sl_send_reply("403", "Please register first"); exit; } Testing and feedback is very much appreciated. For the future: - unregister() to get a $ulc(...) variable as parameter to unregister a specific contact - drop a branch via pv module Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com

[Kamailio-Users] RLS(Resource List Server)
by Yoo Chan Jeon 02 Oct '08

02 Oct '08

Hi, I just want to know how RLS handles SUBSCRIBE messages without using XCAP. I assume that the server already has the list information. I want send the SUBSRIBE message with resource list format: SUBSCRIBE sip:list@domain . . supported:eventlist Accept:application/rlmi+xml Accept:multipart/related I added rls, presence, presence_xml, and pua modlues in the configuration file. I do not have any problems to run the server. Which database should I add list@doamin <list@doamin> to? How do I add the resource list? What kind of format do I need to add a list if I want to add joe@domain, bob@domain, tom@domain ? Do you have some kind of examples? Thanks you. Jeon
