[OpenSER-Users] Presence problems
by Leonard Broman 19 Feb '08

19 Feb '08

Hi! Since my last question on this list I have set up the OpenXCAP and put the necessery documents in the database. I however still have the same problem. On subscribe requests the server responds 481 Subscription does not exist and logs: Jan 21 16:04:24 m2lin3 ./openser[5109]: ERROR:presence:get_stored_info: record not found in hash_table Jan 21 16:04:24 m2lin3 ./openser[5109]: ERROR:presence:handle_subscribe: getting stored info Anyone that can tell me why it's behaving like this?

[OpenSER-Users] Integration of xcap server with openser presence module
by Vincent Nogues 19 Feb '08

19 Feb '08

Dear, I would like to test the open xcap service. So i have installed the openser presence module 1.2 and also the openxcap package but it does not work properly. I have a few questions : Where can I find an up to date installation documentation ? How to make the link between the openser module and the openxcap package ? I have the following errors, someone can help me ? 0(24573) PRESENCE:get_xcap_tree:The query in table xcap for [username]=bob , domain=open-ims.test returned no result 0(24573) PRESENCE: get_subs_dialog:The query for subscribtion for [user]= vno,[domain]= open-ims.test for [event]= presence.winfo returned no result 0(24573) PRESENCE:query_db_notify: Could not get subs_dialog from database 0(24573) PRESENCE:update_subscription:Could not send notify for presence.winfo 0(24573) PRESENCE:get_xcap_tree:The query in table xcap for [username]=vno , domain=open-ims.test returned no result 1(24574) PRESENCE:get_xcap_tree:The query in table xcap for [username]=alice , domain=open-ims.test returned no result 1(24574) PRESENCE:get_xcap_tree:The query in table xcap for [username]=vno , domain=open-ims.test returned no result 1(24574) PRESENCE:get_xcap_tree:The query in table xcap for [username]=bob , domain= open-ims.test returned no result Thanks, Vincent

[OpenSER-Users] openser 1.3.0 and presence module
by Sigrid Thijs 19 Feb '08

19 Feb '08

Hi, we're testing openser 1.3.0 on a linux server with presence module. I'm using the provided configuration file with the following modifications: - loaded the modules mysql, presence, presence_xml - set the following parameters for these modules: modparam("presence|presence_xml", "db_url", "mysql://openser:[secret]@localhost/openser") modparam("presence_xml", "force_active", 1) modparam("presence", "server_address", "sip:[ip]:5060") modparam("presence_xml","integrated_xcap_server", 1) - uncommented the code to handle PUBLISH/SUBSCRIBE requests to the presence module I also configured the mi_datagram module, to receive mi commands. I discovered the following issues. In the main route block, the second if test checks if the request has a to-tag. If the request does not contain a Route header a 404 Not Here response is sent to the request. When a client subscribes for presence, a 202 OK response is received from the presence module, without Record-Route(s). This means future in-dialog requests won't contain the Route header. It also means that for example an un-SUBSCRIBE request is rejected with a 404 Not Here. I worked around this by removing the has_totag () check and not sending a 404 Not Here response when loose_route () returns false. Furthermore I noticed that sometimes, the presence NOTIFY requests do not contain a body. I checked the database, and there was data in the body column in the presentity table for the presence resource. The value in the status column of the watchers/active_watchers table is 1. When I restart openser, the presence descriptions are added to the NOTIFY requests again (the entry in the database did not change). I have to say that we insert some presence states directly in the database via another process. But this is nothing more than an INSERT or UPDATE statement on the presentity table. Do you have any idea why a NOTIFY without body is sent? Do i need to configure something extra? And why does it seem to work after openser has restarted? kind regards, Sigrid

[OpenSER-Users] Regarding RLS Presence Server
by Noble Antony T 19 Feb '08

19 Feb '08

Hi, I have configured Openser as an RLS server. Whenever I send a Subscribe for a resourcelist [ with Reqest-URI as resource list ], I am getting NOTIFY message with empty message body. { I was simply giving some junk list name in request URI} now what I am bothered is the configuration of resource list. how will I form a resource list of a number of subscribers..? Is it possible to use it without an XCAP Server..? *"global lists" *and *"users lists".* How do I form a *"users list"*..? with out using an XCAP..? Is there an RFC to specify the local list ( aka "*users list*" where the sender specify whom all he would like to subscribe for Presence Information ) Thanks, -- Noble Antony T.

[OpenSER-Users] TM module is not 3261 compliant (matching ACK to 2xx)
by Taisto Qvist 18 Feb '08

18 Feb '08

Hi again, I hope I am not being to pushy/obnoxious now, but I was really hoping I could get an anwer from the openser-guru's concerning my issues with the transaction matching code I mentioned in an earlier mail. I and my co-workers feel that the RFC is quite clear on the subject of matching ACK to 2xx, so I would really like to hear what the objections are, since openser does not behave this way. What I was trying to do, was simply to stop the ACKs for 3++ in my script by using "t_check_trans()" and if the ACK did match the transaction, the script would end processing. But I suppose I'm supposed to do this some other way?? Anyway, I hope to hear from someone, indicating what your views on this txn-matching issue is.

[OpenSER-Users] openser is adding itself as a route

Hello, still playing arround with presence and xcap, another thing i would like to know is following query that i can see in my sql logs: username,domain,doc_type,etag,doc_uri,port from xcap where source=1 Q: What does the "source" value stand for, because currently all data records have a value of "0" Also trying currently with "inetgrated xcap_server="0" " but with "xcap_client" module, also with no success...
