[Users] Comparable regex function in openser
by CARTWRIGHT, CORY C (ATTSNET) 23 Mar '07

23 Mar '07

Hello all, I am attempting to add a line to the SDP of a reply using subst. In perl I can do it like this. $test1 =~ s/(.+)\sRTP\/AVP\s18\s(.+)/$1 RTP\/AVP 18 $2\na=fmtp:18 annexb=no\n/g; This ensures I have the whole "m=audio 28104 RTP/AVP 18 101 19" string in the replacement I started with this: subst('/(.*) RTP\/AVP 18 (.*)/\1 RTP\/AVP 18 \2\r\na=fmtp:18 annexb=no\r\n/g'); As most of you probably can see this does not work. Does anyone know if this is possible? Thanks.

[Users] OpenSER 1.2 and NAT
by Andreas Granig 23 Mar '07

23 Mar '07

Hi, When migrating my config from 1.1 to 1.2, far-end NAT traversal doesn't work anymore. Here is what I do: modparam("usrloc", "nat_bflag", 6) ... # register handling: if(!search("^Contact:[ ]*\*") && nat_uac_test("19")) { xlog("L_INFO", "NATed REGISTER\n"); fix_nated_register(); setbflag(6); } if(!save("location")) { # error handling ... } The log message is printed, so NAT is detected. The received-column in the DB also shows the correct NAT-address, but the flag-column is always 0. Any advice? Regards, Andreas This e-mail is confidential and may well also be legally privileged.

[Users] Openser 1.2.0 and exec_dset
by Tobias Lindgren 23 Mar '07

23 Mar '07

Hi all, I'm using exec_dset to run a script which takes the Request-URI and returns a new Request-URI based on the number dialed. In ser.cfg I'm doing this: if (exec_dset("lookup.sh \"$$SIP_RURI\"")) { # Route call } else { # Reply with a cause } Recently a customer started to use SIP-X, and his INVITES with Request-URIs looks like this: sip:1001@192.168.0.1:5060;sipx-noroute=Voicemail Ser responds with "500 Server Internal Error" to these INVITEs, which is due to that my script fails. If I run OpenSER in the foreground with debugging I can see this: 0(20509) exec:w_exec_dset: executing [lookup.php "$SIP_RURI"] 0(20509) exec_str: rtrim sh: line 1: sipx-noroute=Voicemail: command not found How do I correctly escape the SIP_RURI in my openser.cfg to prevent my script from failing? Or is the RURI to long or something? If I run my script from commandline with the request uri, everything is fine. Br, /Tobias

[Users] PRESENCE module issues
by Geir O. Jensen 23 Mar '07

23 Mar '07

Setup; OpenSER 1.2.0 Fresh install (no SERWEB, all the rest) running on MySQL 5.0.22 (Ubuntu 6.06) Two subscribers that publish status, but neither can see status of the other... They are both in the presentity table and listed in the watchers/active_watchers table. When I change status in the client the following occurs on the server; PRESENCE:update_presentity: querying presentity PRESENCE:get_subs_dialog:querying database table = active_watchers PRESENCE: get_subs_dialog:The query for subscribtion for [user]= gojensen,[domain]= test-sip.uninett.no for [event]= presence returned no result PRESENCE:query_db_notify: Could not get subs_dialog from database PRESENCE:update_presentity: Could not send Notify PRESENCE: handle_publish: sip-etag: [SIP-ETag: a.1174552555.9851.2^M /31] I looked through the archives and google very quickly and found something about wrong record sizes and types (for postgresql)... However neither seems to apply in my case. Has anyone got PRESENCE module working, or more importantly, does anyone know how to solve the above issue? // sip:gojensen@uninett.no | h323: 004710012 pstn: +47 73 55 79 23 | fax: +47 73 55 79 01

[Users] memory issues
by Christian Schlatter 23 Mar '07

23 Mar '07

I'm doing sipp performance measurements with openser 1.2 and I was surprised on how much memory the openser processes do allocate when confronted with a high call-per-second load. I observed the following behavior: One sipp instance creates SIP requests that get routed through openser and forwarded to another sipp instance running in UAS mode. The sipp scenario looks like INVITE ----------> 100 <---------- 180 <---------- 200 <---------- ACK ----------> Pause [ 10.0s] BYE ----------> 200 <---------- Nothing special here. The openser instance record routes the SIP requests and forwards them in transaction stateful mode (t_relay) to the sipp UAS instance. The routing script looks like: route{ if (!method=="REGISTER") record_route(); if (loose_route()) route(1); if (uri==myself) rewritehost("xx.xx.xx.xx"); route(1); } route[1] { if (!t_relay()) sl_reply_error(); exit; } ( xx.xx.xx.xx is the IP of sipp UAS) Running sipp with a call rate of 500 cps results in 45 MB of memory allocation per openser process after a few seconds. What could cause this behavior, message queuing maybe? But then again having a message queue of 40+ MB seems to be unrealistic. And the memory consumption goes up the longer the test runs until openser dies because of out-of-memory. I observed the same behavior with openser 1.1 and 1.2. Is this a memory leak or did I miss some settings? And what's the best method to debug memory issues with openser? thanks in advance, Christian

[Users] OpenSER crashes when attempting to use null avp variable
by Asterisk Expert 23 Mar '07

23 Mar '07

Hello, I'm using openser 1.2.0. I have following section in my openser.cfg. avp_db_query("SELECT active, accountcode FROM openser_ip_auth WHERE ip_addr='$src_ip'","$avp(s:active);$avp(s:accountcode)"); xlog("L_INFO", "\n$avp(s:active):::$avp(s:accountcode)\n"); if (!avp_check("$avp(s:active)","eq/1/I")) { xlog("L_ERR", "$si [$Tf]: $rm $fu -> $ru: REGISTER: bad credentials, ask for credentials\n"); #authentication failed www_challenge("", "0"); setflag(1); return; } Basically I'm doing IP based authentication. I have used the similar method in version 1.1 but openser 1.2.0 crashes if the query in avp_db_query returns no rows which keeps those two avp variables null. Is this a bug or I'm doing something wrong? I also tried "==" operator for comparison but it crashes whenever it is trying to access one of those two variables. -- Regards Ruchir Brahmbhatt Ecosmob Technologies
