[Serusers] SEMS stops taking audio with a particular ATA
by SIP 10 Jul '07

10 Jul '07

This is kind of odd, and should really probably be directed toward the SEMS list, but I thought I'd pose it here first to see if anyone had seen it. A particular user keeps calling our SEMS server, and each and every time he does, it crashes. It ONLY happens with that one user, and only with his Cortelco ATA (an identical model to another we have being used on our network with no problems). We get this in the log: Jul 9 20:26:32 proxy Sems[17552]: Error: (AmThread.cpp)(start)(83): pthread create failed with code 11 Jul 9 20:26:35 proxy Sems[17552]: Error: (AmThread.cpp)(stop)(101): pthread_detach failed with code ESRCH: thread could not be found. And then poof, the SEMS server stops sending audio anymore and has to be killed and restarted (it still runs and accepts connections). Any ideas? Nothing much comes up on a google search for this error. N.

[Users] statefull handling of 6xx responses
by Christian Schlatter 09 Jul '07

09 Jul '07

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 09 Jul '07

09 Jul '07

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 09 Jul '07

09 Jul '07

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

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.
