[OpenSER-Users] presence caching and retrieval

by Sigrid Thijs

Hi, I was wondering, when a SIP user publishes his presence to the openser presence module, is this presence data cached in memory by the server or is this immediately stored in the database? Is this somehow configurable? If the presence data is cached in memory, is there an interface available for an external server to query the presence of one or more resources? In particular, we are looking for a performant way to query the presence of multiple users (for example 20). We would like to avoid the overhead of creating a SIP subscription for each resource: - to avoid traffic overhead - we only need to know the current presence of the resource(s) and are not interested in future presence changes. Do you have any suggestions on if/how this can be achieved with openser? kind regards, Sigrid Thijs

Hello all, I've got a working conf on which RTPs work perfectly with TCP, but fails to work with UDP... can anyont tell me why??

[OpenSER-Users] INVITE, exec_dset(), and BYE

by Juan Carlos Castro y Castro

I have a scenario in which an OpenSER machine distributes load among several Asterisk machines for outgoing PSTN. I use an external program which I call through exec_dset() to select which server a call goes to. I use record_route(). All calls are completed OK, but when I dial from some SIP user-agents and hang up from the caller side, OpenSER gets crazy and doesn't know where to route the BYE to. Here's the reason: Good scenario: - I make a call to <5551234@mydomain> - OpenSER calls exec_dset, which turns it into <providercode#5551234@chosenserver> - Call is answered - I hang up - My UA sends a BYE like this: "BYE sip:providercode#5551234@chosenserver SIP/2.0" - I get an OK back, all is well. (Sometimes the # in the uri above is sent as %23, but it works either way) Bad scenario: - I make a call to <5551234@mydomain> - OpenSER calls exec_dset, which turns it into <providercode#5551234@chosenserver> - Call is answered - I hang up - My UA sends a BYE like this: "BYE sip:5551234@mydomain SIP/2.0" - My openser.cfg doesn't know how to handle that and I get a "Loop Detected" back. The destination never gets a hangup signal. Is the second UA from the "bad" scenario disrespecting the RFC? Do I have any recourse to route a BYE that comes like that to the right Asterisk server? Thanks, Juan

[OpenSER-Users] OpenXCAP: no percent-encoded URI allowed? can't fetch element that beneath multiple-folded elements?

by KevinKinnan

The OpenXCAP 0.9.7(version 0.9.7) allows the HTTP URI that is not percent-encoded while the percent-encoded URI is rejected by the server. There is no problem of installation. Two types of http URIs are shown below: Accept: http://xcap-root/resource-lists/users/sip:alice@example.com/index/~~/resour…"friends"] Reject: http://xcap-root/resource-lists/users/sip:alice@example.com/index/~~/resour… Another problem is about fetching element that within multiple-folded elements, for example: <list name="friend"> <entry uri="sip:alice@example.com"> <display-name>Alice</display-name> </entry> <entry uri="sip:bob@example.com"> <display-name>Bob</display-name> </entry> </list> <list name="closefriends"> <entry uri="sip:tom@example.com"> <display-name>Tom</display-name> </entry> <entry uri="sip:mike@example.com"> <display-name>Mike</display-name> </entry> </list> If fetching the element of "mike", the responsed to the following URI is "404 Not found". http://xcap-root/resource-lists/users/sip:alice@example.com/index/~~/resour… However, an alternative way of uing element sequence number works. http://xcap-root/resource-lists/users/sip:alice@example.com/index/~~/resour… Hope anyone can give me some clues, thanks a billion Regards, Kevin _________________________________________________________________ MSN 中文网，最新时尚生活资讯，白领聚集门户。 http://cn.msn.com

Re: [OpenSER-Users] CDRTool help?

by Andy Smith

Sorry, not all of the text I originally sent has appeared on the list archives, so here is the full email another time! :P Hi, can anyone provide any advice on getting CDRTool to work? I have installed CDRTool 6.0 on a Debian Linux system 2.6 Kernel with Apache/2.2.6 (Unix) PHP/5.2.5 I am attempting to get it to work with OpenSER only (I have commented out the Asterisk and sip_trace sections in global.inc) and I am recieving the error: Error initializing CDRTool datasource >From in my web browser. It seems that in callsearch.phtml "$cdr_source" is not being set, but I dont understand why not and I am not sure how to get more debugging info out of the whole thing (Im not used to PHP), I dont see any errors in the syslog :( With regards global.inc, I believe all database usernames and passwords are setup and have successfully tested connecting to all databases with this data - and I believe all db_class sections have the corresponding sections as required (the username, password, tablename etc). thanks for any help! Andy.
