[Users] $ru, $rU, $ru/username, $ruri/username, usage

by Greg Fausak

I want to use the RURI username in an avp query. I've seen a bunch of different ways to select it. Which way is correct? I am currently using $ruri/username, because I got an error with $rU. http://openser.org/docs/pseudo-variables.html shows '$rU', which complains when I try to reference that. Aug 21 06:55:58 www openser[89119]: ERROR:avpops:fixup_pushto_avp: unsupported destination "$rU"; expected $ru,$du,$br Aug 21 06:55:58 www openser[89119]: ERROR: fix_actions: fixing failed (code=-1) at cfg line 82 It's weird, the source code in items.c reads: {{"ru", (sizeof("ru")-1)}, /* */ { XL_RURI, 0, xl_get_ruri, {{0, 0}, 0}, {0, 0}}}, {{"ruri", (sizeof("ruri")-1)}, /* */ { XL_RURI, 0, xl_get_ruri, {{0, 0}, 0}, {0, 0}}}, {{"rU", (sizeof("rU")-1)}, /* */ { XL_RURI_USERNAME, 0, xl_get_ruri_attr, {{0, 1}, 0}, {0, 0}}}, Is there a list of the variables that are available in an avp operation? -g

[Users] Please help for guiding serweb installation in openser

by Ferianto siregar

Dear all, Thank you very much to all of you for help me to answer my question about serweb before. So, based on your suggestion, I tried to install serweb 0.9.3 for my openser server. But, when I tried to install it, I am confused. I don`t understand about the installation note that I have got from untar the serweb 0.9.3 packet. These are some questions that I need to ask: 1. Where should we untar the serweb 0.9.3 packet? Should we untar it in root or anywhere we like? Because when we untar it, there will be a serweb folder in the location where we untar it (for example, when we untar the packet in root there will be a serweb directory in root) . This serweb folder also contain html directory and phplib directory. As I know, There are also html directory in /root/var/www. So, What directory should I use? Should I delete the html directory and phplib directory in /root/var/www/? 2. Is there any relationship between the html directory in /root/var/www and html directory from /root/serweb? Which one should I use? 3. In the installation note I got this message : "install it, unpack the distibution on your webserver so that the directory html is in document root and phplib is not accessible via web" Can anybody help me to explain what this message means? and give me an example? 4. If I can make a wish for all of you, I do hope anybody can share the serweb configuration that she/he has configured to me. So, it can become the guidelines for me. That `s all the question that I got when I tried to install the serweb. I am confused. I do hope anybody can help me because I am new in this system. Thank you very much for your help. Thanks Regards, Ferianto --------------------------------- Do you Yahoo!? Everyone is raving about the all-new Yahoo! Mail.

[Users] t_on_failure doesn't

by Nathan Hawkins

I'm trying to use the LCR module to do a failover between two gateways. For testing purposes, I have a gateway record pointed at an IP that isn't used. The problem is, I can't seem to get OpenSER to fail over to the other gateway. I want to use TCP (with TLS when I'm done), but I get this: Jul 20 15:36:57 asiago /usr/sbin/openser[11896]: route[6]: routing to INVITE sip:MYDID@MYIPADDRESS:5060;transport=tcp Jul 20 15:37:17 asiago /usr/sbin/openser[11896]: ERROR: tcp_blocking_connect: timeout (10) Jul 20 15:37:17 asiago /usr/sbin/openser[11896]: ERROR: tcpconn_connect: tcp_blocking_connect failed Jul 20 15:37:17 asiago /usr/sbin/openser[11896]: ERROR: tcp_send: connect failed Jul 20 15:37:17 asiago /usr/sbin/openser[11896]: msg_send: ERROR: tcp_send failed Jul 20 15:37:17 asiago /usr/sbin/openser[11896]: ERROR:tm:t_forward_nonack: sending request failed (IP and username censored.) OpenSER sends this to the caller: SIP/2.0 477 Unfortunately error on sending to next hop occurred (477/TM) Why can't I catch this with either the return code from t_relay or the failure route? It will go to the failure route if I get a reply back from the next hop. But I need to fail to the other gateway. The relevent parts of the configs are shown below. (Addresses censored.) Any help would greatly appreciated. Thanks, ---Nathan Config snippet: # ok, so maybe try a gateway... if( load_gws() ) { xlog("L_INFO","route[3]: gateway routing $rm $ru"); t_on_failure("1"); route(6); return; } } route[6] { xlog("L_INFO","route[6]: $rm $ru"); t_on_failure("1"); t_on_reply("1"); if (!next_gw()) { xlog("L_INFO","route[6]: no more gateways for $ru"); exit; } xlog("L_INFO","route[6]: routing to $rm $ru"); if(!t_relay()) { xlog("L_INFO","route[6]: t_relay returned $rc"); sl_reply_error(); } return; } failure_route[1] { xlog("L_INFO","failure_route[1]: $rm $ru"); t_on_failure("1"); if(t_check_status("404")) { xlog("L_INFO","failure_route[1]: failing call with 404 for $ru"); return; } if (!next_gw()) { xlog("L_INFO","route[6]: no more gateways for $ru"); exit; } append_branch(); xlog("L_INFO","failure_route[1]: sending $rm $ru"); if(!t_relay()) { xlog("L_INFO","route[6]: t_relay returned $rc"); } return; } Gateways: mysql> select * from gw where grp_id=4; +---------+--------+-----------+------+------------+-----------+--------+ | gw_name | grp_id | ip_addr | port | uri_scheme | transport | prefix | +---------+--------+-----------+------+------------+-----------+--------+ | ithaka | 4 | CENSORED | 5060 | NULL | 2 | NULL | | larink | 4 | BAD_ADDRESS | 5060 | NULL | 2 | NULL | +---------+--------+-----------+------+------------+-----------+--------+ 2 rows in set (0.00 sec) ithaka is a working OpenSER proxy. larink is an empty IP address.

[Users] SER + phone provisioning server - what are the options?

by Mahatma Sarasvati

Hi All, I'm tired of manually editing text files. What solutions are available for avoiding manual editing and saving of Cisco .cnf files for individual phones while using SER or OpenSER? I've got 80+ phones in my organization and I'm tired of manually managing the phone .cnf files I'm imagining some piece of code that auto-generates the files on command or on a schedule based on entries in the MySQL database. Maybe a column can be added to the Subscriber table or somewhere that holds the MAC address of the phone? Or is there a way to get the phone to get its default config via TFTP and its user information via http? Thanks, M _______________________________________________ Serusers mailing list Serusers(a)lists.iptel.org http://lists.iptel.org/mailman/listinfo/serusers

[Users] Bug in nathelper module or in the replace() function

by Federico Giannici

If a message body is modified by both force_rtp_proxy() and replace( "^Content-Length:", "l:" ) then the resulting message is corrupted. The message size is updated but the header field name appear in both the short and long form. Here it is an example: l:Content-Length: 403 The result is the same if I reverse the order of the two operations too. BTW, I use that replace call (and others) when the message is large to prevent it to fragment. Bye. -- ___________________________________________________ __ |- giannici(a)neomedia.it |ederico Giannici http://www.neomedia.it ___________________________________________________

[Serusers] SER + SEMS in TCP case

by Pat wang

Hi all, Has anyone tried SER + SEMS in TCP mode yet? I mean the UAs use TCP as transport protocol. I am able to setup SEMS as a conference server. I found "transport=TCP" is missing in the Contact header in the 200ok/SDP after SEMS answers the call. Eyebeam seems not like it and does not response to that 200ok. Result is SER keeps sending that 200ok/SDP till timeout. I tried to use textop module to catch that 200ok then replace the Contact header with a correct one but SER and SEMS communicate via fifo so I am not able to do so. Can anyone help me solve this issue please? cheers, Patrick
