[OpenSER-Users] Radius accounting and Dialog
by David Villasmil 14 Jun '08

14 Jun '08

Hello all, Question: I know BYE messages aren't gusranteed to be delivered as far as accounting is concerned. BUT, Could Dialog and TM modules be used in the following way: Setting a timeout on the dialog to receive the first message, i.e. 100 or 180. Instruct the UAC to send a message every 60 senconds to our server, and reseting that timer when we receive it, so that we know that the call hasn't ended. If we don't receive that "keep-alive" message we end the dialog with a BYE (from an outside script) so that, even if the caller or calle dropped out of the internet, we have a START and END for this call, maybe loosing a few senconds. Is this possible at all? Thanks a lot! David

[OpenSER-Users] How to detect if both UAs are from the same LAN
by Pete Kay 14 Jun '08

14 Jun '08

Hi, I am using .nat_uac_test to detect if the UA is from behind a NAT and if so use rtpproxy. However, if both UA are behind the "same" NAT, is there anyway to tell? If both UAs are from the same LAN then I don't need to apply rtpproxy. What would be a good way to do that? Any suggestion will be greatly appreciated. Regards, Pete

Hello all, I'm trying to configure the LCR module, but I'm running into a little problem, I don't get any errors but it is not routing the call properly, this is my lcr info: openserctl lcr show database engine 'MYSQL' loaded Control engine 'FIFO' loaded lcr routes +----+--------+----------+--------+----------+ | id | prefix | from_uri | grp_id | priority | +----+--------+----------+--------+----------+ | 1 | 001 | | 1 | 1 | +----+--------+----------+--------+----------+ lcr gateway groups +--------+----------+ | grp_id | grp_name | +--------+----------+ | 1 | GWs | +--------+----------+ lcr gateways +---------+---------------+------+------------+-----------+--------+-------+---------------+ | gw_name | ip_addr | port | uri_scheme | transport | grp_id | strip | prefix | +---------+---------------+------+------------+-----------+--------+-------+---------------+ | USA | 1.2.3.4 | 5060 | 1 | 1 | 1 | 2 | 99 | +---------+---------------+------+------------+-----------+--------+-------+---------------+ I'm sending the following call: Jun 14 07:49:31 rgi-sip /sbin/openser[9458]: DBG:core:parse_msg: SIP Request: Jun 14 07:49:31 rgi-sip /sbin/openser[9458]: DBG:core:parse_msg: method: <INVITE> Jun 14 07:49:31 rgi-sip /sbin/openser[9458]: DBG:core:parse_msg: uri: < sip:0013058883456@9.8.7.6:5060> Jun 14 07:49:31 rgi-sip /sbin/openser[9458]: DBG:core:parse_msg: version: <SIP/2.0> my script says: # routing to the public network if (!load_gws()) { xlog("L_INFO","LCR: Unable to load gateways"); sl_send_reply("503", "Unable to load gateways"); exit; }else{ xlog("L_INFO","LCR: Sending to $td\n"); } if(!next_gw()){ sl_send_reply("503", "Unable to find a gateway"); exit; } t_on_failure("2"); if (!t_relay()) { sl_reply_error(); }; exit; On the syslog i get the message: LCR: Sending to 9.8.7.6 <-- This, although the IP is wrong, I KNOW it didn't fail loading the gateways... where 9.8.7.6 if my sever's IP. Why is it not matching? Thanks a lot David

[OpenSER-Users] OPENSER: 3 years
by Daniel-Constantin Mierla 14 Jun '08

14 Jun '08

Hello everybody, today is the third anniversary of the OPENSER project. There were three years of development, community events and fun. And it is more to come... I want to thank to all that invested time and money into the project, writing code, offering support on mailing lists and forum, traveling around the world to promote the project, developing documentation and tools, disclosing their usage of OPENSER in production environments setting trust to this SIP server. It will be a huge list to detail everything, openser.org and google reveal very good the OPENSER environment for the past three years. Looking forward to next year! Cheers, Daniel -- http://www.asipto.com

[OpenSER-Users] Loose route problem or misunderstanding
by Watkins, Bradley 13 Jun '08

13 Jun '08

I'm having a problem using loose_route, and I'm not sure if it's a bug/feature/misunderstanding. I have a B2BUA (Asterisk) running on the same system as OpenSER, and in my failure_route for voicemail I direct calls there which actually sends them on to the voicemail server. If someone 'zeroes out' of voicemail, to be forwarded to the operator, the voicemail server issues a re-INVITE to redirect media. This is where the problem comes in. If I try to loose_route this re-INVITE, it fails. However, putting the B2BUA on a different system works fine. This is running OpenSER 1.2.3 currently, though I'm not particularly averse to upgrading to the latest 1.3.x if for some reason this is something that's been resolved there. Any suggestions? Thanks in advance, - Brad

Re: [OpenSER-Users] Radius accounting and Dialog

SORRY TO HAVE REPLIED TO YOUR EMAIL!!! I hate it when gmail does that! Thanks, It rather very easy, I need all calls to go through the media-proxy. I'm testing behind nat, server is on the internet. If I make a call from one UAC natted to another UAC natted, it works fine, rtps go to the proxy. If I call from behind NAT to echo test, I don't get any audio. rtps go directly to the echo test server's IP, but i don't get anything back. I'm doing something very wrong, I've modifed the script like a thousand time, and still...

by Pablo Bertuzzi 13 Jun '08

13 Jun '08

Hello everyone, i am testing the carrierroute module to do the following: -If destination starts with 1760, the call is sent to PSTN GW. -If destination starts with 1305, the call is blocked. The lab works as desired, however i am getting this error: ERROR:carrierroute:carrier_rewrite_msg: during rewrite_uri_recursor, uri 13054941522 , carrier 0, domain 0 These are my tables: mysql> select * from carrierroute; +----+---------+-------------+--------+------+-------+---------------+----------------+----------------+---------+ | id | carrier | scan_prefix | domain | prob | strip | rewrite_host | rewrite_prefix | rewrite_suffix | comment | +----+---------+-------------+--------+------+-------+---------------+----------------+----------------+---------+ | 1 | 0 | 1760 | 0 | 1 | 0 | 70.165.183.36 | | | NULL | | 2 | 0 | 1305 | 0 | 1 | 0 | | | | NULL | +----+---------+-------------+--------+------+-------+---------------+----------------+----------------+---------+ 2 rows in set (0.00 sec) mysql> select * from route_tree; +----+---------+ | id | carrier | +----+---------+ | 0 | default | +----+---------+ 1 row in set (0.00 sec) And this is my config: if (is_method("INVITE")) { if(!cr_rewrite_uri("0", "call_id")){ sl_send_reply("403", "Not allowed"); exit(); } } any ideas? best regards, Pablo.
