Hi guys ! I'm new here and I came to the list to try solve a problem first. =) Good.... I have a SIPProxy installed in my machine working with Openser 1.1.1. Now I need to do this SIPProxy answer for 2 different domains and to do something depending of where request came. Now, I have almost everything functional (like freeradius and mediaproxy and mysql requests), but the Openser can't startup..... For a while, I copy his binary (//usr/local/sbin/openser/) to/ /usr/local/sbin/openserhost/ and change the openser file's content -- where was openser.cfg now is openserhost.cfg) -- with a hexadecimal editor (GHex). I created a //etc/init.d/openserhost , /etc/default/openserhost/ and a/ /usr/local/etc/openserhost/ /too. Finally, I edit the "port" (to 5070) and de informations to database connect in new config file. When I try start the software, I get a error like this: *siphost01:/usr/local/etc/openser# /etc/init.d/openserhost start Not starting openserhost: invalid configuration file! siphost01:/usr/local/etc/openser# * Continuing, looking for a log, I see the /var/log/openser/openserhost.log and got: * Oct 9 09:57:17 siphost01 kernel: openserhost[12020]: segfault at 0000000000000004 rip 00000000f7f6696e rsp 00000000ffcccaec error 4 Oct 9 10:04:33 siphost01 kernel: openserhost[12207]: segfault at 0000000000000004 rip 00000000f7fa096e rsp 00000000ffbc49ec error 4 Oct 9 10:05:36 siphost01 kernel: openserhost[12241]: segfault at 0000000000000004 rip 00000000f7f8096e rsp 00000000fff58d7c error 4 Oct 9 10:54:39 siphost01 kernel: openserhost[13443]: segfault at 0000000000000004 rip 00000000f7f7b96e rsp 00000000ffc52a6c error 4* And that is All..... Sorry if I'm doing somethig stupid or if my english is very very bad.... I'm "new" in "Sr world" and I'm brazilian... =) Wait someone helpme with this.... Regards......

Permission module error
by Shrouk Khan 09 Oct '10

09 Oct '10

hi, i have been trying to use the allow_trusted() to allow or disallow invite request from certain IP address. This is the block that i am using: loadmodule "permission.so" ...... ........ if(is_method("INVITE")){ if(!allow_trusted()){ sl_send_reply("403","Address Not allowed"); exit; } } but trying to restart kamailio after this fails. and from the syslog it says: Oct 9 03:19:49 ubuntu kamailio: ERROR: <core> [sr_module.c:378]: ERROR: load_module: could not find module <permission> in <//lib/kamailio/modules_k/://lib/kamailio/modules/> Oct 9 03:19:49 ubuntu kamailio: : <core> [cfg.y:3330]: parse error in config file //etc/kamailio/kamailio.cfg, line 151, column 12-26: failed to load module Oct 9 03:19:49 ubuntu kamailio: : <core> [cfg.y:3333]: parse error in config file //etc/kamailio/kamailio.cfg, line 356, column 21: unknown command, missing loadmodule?#012 I think i forgot to compile kamailio with the support of permission module . but i do not see it anywhere in the ignore list either. can anyone tell me what could be the problem -- Regards Shrouk Khan (Khan) System Administrator / Telecommunication System Developer Office: +354 4400807 (Reykjavik) +44 2031370800 (London) Mobile: +66 875049439 (Bangkok) Web: www.softverk.is Reykjavik, Iceland // London, UK // Bangkok, Thailand

Evaluate Perl Return Value in Routing Logic
by "Nicolas Rüger" 08 Oct '10

08 Oct '10

Hello, is there any way to use or evaluate the return-statements of a perl-script in kamailio.cfg? I tried the following in the Routing Logic in kamailio.cfg: if (is_method("INVITE")) { if (perl_exec("my_perl_subroutine") == -1){ xlog("PERL returns -1 \n"); } } Doesn't work. The bad thing is that the return-values of the - perl_exec("XXX") - call are not the same that the perl subroutine "XXX" returns. That's at least what I strongly believe after testing. I do need to read/evaluate the return-value of the perl-subroutine in the Routing Logic to define different routes depending on what the perl-subroutine returns. Is there any way to do that??? Thank you for your help in advance. Regards, Nicolas -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT! Jetzt freischalten unter http://portal.gmx.net/de/go/maxdome01

how to check if t_newtran() has already been called?
by Juha Heinanen 07 Oct '10

07 Oct '10

can t_check_trans() be also used to check if t_newtran() has been called on the request earlier in the script? if so, is it so heavyweight thing that it would be better to set a flag when t_newtran() is called and then test the flag? -- juha

t_relay_cancel usage
by Juha Heinanen 07 Oct '10

07 Oct '10

in tm readme there is this kind of example regarding use of t_relay_cancel: if (method == CANCEL) { if (!t_relay_cancel()) { # implicit drop if relaying was successful, # nothing to do # corresponding INVITE transaction found but error occurred sl_reply("500", "Internal Server Error"); drop; } # bad luck, corresponding INVITE transaction is missing, # do the same as for INVITEs } if proxy is processing all invites statefully, why anything needs to be done when invite transaction corresponding the to cancel is missing? isn't it a case of unmatched cancel and the cancel could just be dropped? -- juha

Question about early media
by Asim Riaz 07 Oct '10

07 Oct '10

Hi List, Phone-1 ------->Proxy1 (kamailio)-------------->Proxy-2(3rd party) -------------> phone 2 Calls from phone-1 to phone-2, proxy-2 is sending early media without sdp in provisional reply, this early media is sourced from different port than response (200), what port proxy-1 will use to transmit actual voice, the source port in early media or source port in response(200) which is different than early media. Thanks, Asim

WARNING: script writer didn't release transaction
by Juha Heinanen 07 Oct '10

07 Oct '10

after playing with t_newtran(), i started to get these to syslog: Oct 7 15:39:11 sip /usr/sbin/sip-proxy[26119]: WARNING: tm [t_lookup.c:1543]: WARNING: script writer didn't release transaction as far as i remember, in k these messages were not printed, because transactions were freed automatically when script ended. also, example in section 1.3.3. nonce_count of auth module does not include any t_release() calls. where exactly should they be put? -- juha
