[OpenSER-Users] Error using openser
by Marcio Ribeiro 20 Nov '07

20 Nov '07

Hi, I'm trying to set up openser with TLS support with mysql database, on Debian. In fact, i could not even start openser with succes. When using "openserctl start": Starting OpenSER: ERROR: PID file /var/run/openser.pid does not exist -- OpenSER start failed when using "openser": Listening on udp: 127.0.0.1 [127.0.0.1]:5060 udp: 164.41.14.213 [164.41.14.213]:5060 tcp: 127.0.0.1 [127.0.0.1]:5060 tcp: 164.41.14.213 [164.41.14.213]:5060 Aliases: tcp: unbvoip3.cic.unb.br:5060 tcp: localhost:5060 tcp: localhost.localdomain:5060 udp: unbvoip3.cic.unb.br:5060 udp: localhost:5060 udp: localhost.localdomain:5060 *: voip.unb.br:* but it's not running, since my "ps aux | grep openser" cannot find it. Sugestions??? Thanks, Marcio

[Serusers] from uri???
by Roderick 19 Nov '07

19 Nov '07

Hi list, I'm looking how to forward a call to a PBX if it comes from a certain number. Just to illustrate, this would call forward to a pbx if you're dialing 123: if (uri=~"^sip:123@") { #Forward to PBX if calling 123 } What I want is something like if (from=~"^sip:123@") { #Forward to PBX if calling FROM 123 } Is there something like this??? Thanks for your help, Roderick

[OpenSER-Users] check_from() and calls from a PBX
by Iñaki Baz Castillo 19 Nov '07

19 Nov '07

Hi, I've a PBX (Asterisk) registered in OpenSer as user "pbx@domain". When Asterisk receives a call from PSTN it calls to OpenSer users with From: From: <sip:PSTN_number@domain> But of course, this can't validate "check_from()" since From username (PSTN_number) and auth username (pbx) are differents. As I solution I don't do "check_from()" if From username is "pbx" but of course, it can create security problems. Other solution is to force "From" username in PBX outgoing calls, but with this the callerid number will be "PBX" (that is not very cool for end users xD). Another solution is using "trusted" ips, but this is not valid for me since Asterisk is behind a NAT and dynamic IP, and because there can be multiples PBX for each domain of OpenSer and I don't want they to have privileges. Is there any other approach for this? Thanks for any suggestion. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

[OpenSER-Users] lookup("location") and CPL locations set
by Daniel 19 Nov '07

19 Nov '07

Hi all, I have a question: in this scenario route(1) { ..... ...... lookup ("location"); cpl_run_script("incoming", "force_stateful"); .... ... } is the location (R-URI address), re-writed by the "lookup" function, part of the CPL locations set ? Or CPL doesn't care about this and it see the locations set empty? Regards daniel -- Daniel Grotti ________________________ e-mail : d.grotti(a)gmail.com

[OpenSER-Users] Openser performance with rtpproxy
by Stanisław Pitucha 19 Nov '07

19 Nov '07

Hey I've got a simple openser configuration working with rtpproxy. It's mostly copied from http://www.voip-info.org/wiki/view/OpenSER+And+RTPProxy but I don't handle registration and do only nat helping (for current testing I don't even save location - Contact / URI headers are enough). I've tried setting up sipp (no authorization, just invite, send 7 secs rtp, bye) and standard UAS scenario on the other end. I start to get retransmissions / timeouts when I use 2 hosts and ~70 simultaneous connections (total). Typical delay is ~250ms (not network delay - it's on gigabit LAN). I've used the same sipp scenarios for asterisk before and got up to 700 sessions running correctly, so I believe the problem is with openser config here. How can I check what causes the problems exactly? Is there any typical performance problem? I've tried googling already - couldn't find anything obvious. I'm running svn version. Thanks for ideas.

[OpenSER-Users] [CPL] ERROR:cpl-c:run_priority_switch: error parsing attr [0][9]
by Iñaki Baz Castillo 19 Nov '07

19 Nov '07

Hi, I'm just starting with CPL and I don't know if this mail should go to devel list or users list. I load a very simple CPL script sucessfully: $ openserctl fifo LOAD_CPL sip:ibc@domain /etc/openser/cpl/ibc(a)domain.xml 200 OK The XML is this one: <?xml version="1.0" encoding="UTF-8"?> <cpl> <incoming> <time-switch> <time dtstart="9" dtend="5" wkst="MO|TU|WE|TH|FR"> <lookup source="registration"> <success> <proxy /> </success> </lookup> </time> <otherwise> <location url="sip:angel@domain"> <proxy /> </location> </otherwise> </time-switch> </incoming> </cpl> But when OpenSer runs: cpl_run_script("incoming","force_stateful"); I get in the logs: ERROR:cpl-c:run_priority_switch: error parsing attr [0][9] ERROR:cpl_c:cpl_run_script: script error I can't understand. I suppose that that XML check is done when loading the file with FIFO command. Why then I get a "error parsing" during OpenSer script? is it normal? Thanks for any explanation. Best regards. -- Iñaki Baz Castillo

[OpenSER-Users] CPL serial call attempt
by Daniel 19 Nov '07

19 Nov '07

Hi all, I have this problem. I have 2 contacts for one user subscriber, so in LOCATION tables, after REGISTER session I have: ID user contact q 12 A A@IP_X 1 13 A A@IP_Y 1 14 B B@IP_Z 1 so, B calls A and A has an incoming CPL script. In this script I'd like to call the 2 A's contacts in sequential order: The script is after looup("location"), so the R-URI is just A@IP_X (because it has lowest ID) SRIPT user A: <cpl> <incoming> <location url="sip:A@IP_Y" priority="0.3"> <proxy timeout="10" ordering="sequential" /> </location> </incoming> </cpl> Whit this script I hoped to add A@IP_Y to location set (that already included A@IP_X) with priority 0.3, and then call A@IP_X as first (it has priority=q=1) and then, if I no aswer after 10sec, call A@IP_Y (that it has lowest priority). CPL don't add A@IP_Y to the location set, but it rewrites the location (it removes the old R-URI, A@IP_X) with A@IP_Y and it call only this contact. Is there a sense in what I've write? if yes, where is the problem? regards, daniel -- Daniel Grotti ________________________ e-mail : d.grotti(a)gmail.com

[OpenSER-Users] record_route() for responses
by Klaus Darilion 19 Nov '07

19 Nov '07

Hi! I just was thinking about the follwing scenario_ client a--->proxy--->client b the proxy does record routing a calls b b send back 200 OK, but does NOT mirror the Record-route headers. in-dialog requests sent from a to b will bypass the proxy, thus bypass proxy security features (e.g. removing the credentials). Thus IMO we should have some settings which allow the proxy to add RR header also for relayed response if during request processing record-route was called and the proxy misses itself as the top RR header. what do you think? regards klaus
