[Users] statefull handling of 6xx responses

by Christian Schlatter

RFC 3261 defines that upon reception of a 6xx response, a proxy SHOULD cancel all forked dialogs and send back the 6xx as the final response to the upstream UA. --- rfc 3261, section 16.7 ------- Under the new rules, upon receiving a 6xx, a proxy will issue a CANCEL request, which will generally result in 487 responses from all outstanding client transactions, and then at that point the 6xx is forwarded upstream. ---------------------------------- Some call forking experiments have shown that openser 1.2 does not follow these rules, instead it seems to disregard any 6xx response and continue with normal processing of existing forked dialogs. E.g. if a call forks to five phones and one of them sends back a 603 Declined response, the other four phones continue to ring until fr_inv_timer fires and failure_route is called with a status of 408 Timeout. Is it possible to make openser more SIP RFC compliant through configuration or does this need a code change? thanks, Christian

[Serusers] Problems with avp_db_load and db_query

by Ravin Suri

Hello everyone, I am facing a problem trying to load data from MySQL in ser.cfg. I need to load the subsciber's email address in order to pass it to SEMS. I've tried two modules (avpops and db_ops) both with no success. I am using Ser 2.0.0-rc1 and I added an 'email' column to the uri table. Here is the DB schema (only 1 row shown without did, flags and scheme colums): +--------------+------------------------------+--------------------------+ | username | uid | email | +--------------+------------------------------+--------------------------+ | sb4157762898 | sb4157762898(a)sq2.doclinx.com | sb4157762898(a)doclinx.com | | +--------------+------------------------------+--------------------------+ A. avpops module. I have the following module params: modparam("avpops", "avp_table", "uri") modparam("avpops", "uid_column", "uid"); modparam("avpops", "avp_aliases", "email=i:47") modparam("avpops", "db_scheme", "email_scheme:table=uri;uid_col=uid;value_col=email;value_type=string") Then when I'm going to forward to SEMS: avp_db_load("$to", "$email/$email_scheme"); xlog("L_INFO", "route INBOUND[%rm]: voicemail, email=%$email, from: [%fu], To: [%tu]\n"); append_hf("P-App-Name: voicemail\r\n"); append_hf("P-App-Param: Email-Address=%$email\r\n"); rewritehostport("127.0.0.1:5070"); t_relay_to_udp("127.0.0.1","5070"); Here is the appropriate excerpt from the SER log (from the xlog statement above): Jul 9 13:12:39 sq2 /usr/local/sbin/ser[5595]: route INBOUND[INVITE]: voicemail, email=<null>, from: [sip:sb7037160791@sq2.doclinx.com], To: [sip:sb4157762898@sq2.doclinx.com] 2. db_ops module. I have the following module params: modparam("db_ops", "declare_query", "select/uri/email/uid///%$t.uid"); Then when I'm going to forward to SEMS: $email = @db_query[0]; xlog("L_INFO", "route INBOUND[%rm]: voicemail, email=%$email, from: [%fu], To: [%tu]\n"); append_hf("P-App-Name: voicemail\r\n"); append_hf("P-App-Param: Email-Address=%$email\r\n"); rewritehostport("127.0.0.1:5070"); t_relay_to_udp("127.0.0.1","5070"); This makes SER fail on startup with this message: 0(5693) Unable to resolve select 'db_query' at level 0 0(5693) BUG: route.c:492: Unable to resolve select ERROR: error -1 while trying to fix configuration I have followed the README file in db_ops to the letter. What am I missng? I'd be be happy to post ser.cfg and the log file. Thank you very much for your help. Best regards, - Ravin

[OpenSER-Users] NOTIFY not forwarded upon PUBLISH

by KUMAR

Hi all, I'm using openser from the SVN. The configuration file that I'm using is attached. The server upon receiving PUBLISH, replies with a 200 OK. But doesnt send out NOTIFY. I want to use the presence modules, without XCAP. I just want the server to send out SUBSCRIBE on the UA's behalf, by looking up the values from the database and also to send out NOTIFY on the UA's behalf, whenever it receives the PUBLISH, all without having anything to do with XCAP. Is this possible ? If yes, what changes do I need to do with the configuration file. Thank you in advance. Kumar

RE: [OpenSER-Users] crash when checking empty destination uri

by Papadopoulos Georgios

Hi Daniel, Thank you for looking into this. I got from SVN the patch for rev. 2420 and I applied it to my 1.2 branch. OpenSER still crashes at the same point. Did I get the right patch? The one I have changes one line on route.c and transformations.c. I will add it at the end of the email.

Re: [Serusers] How SER communicate to other SIP server

by roayu

Hi, Szasz! I found that both UAC are only sending out packets but didn't receive any packets from either party. For instance, softphone A only send packets to serverA whereas softphone B only send packets to serverB. Is there any other settings that I need configure as well? Which firewall settings that I need to check (server/client)? Thanks.
