Re: [SR-Users] Doubs about using append_branch ...

It sounds like what you need is to do branch-specific logic in a branch route: http://www.kamailio.org/dokuwiki/doku.php/core-cookbook:3.0.x#branch_route Not all functions can be used in a branch route, but those that can be operate only on that branch.

Regex Transformations
by Brandon Armstead 22 Jul '10

22 Jul '10

Hello, I am trying to match a multi-line psuedo variable, i.e. $rb However I am wishing to pull out the payload values i.e. "0 18 101" "18 101" etc.. etc... I am having trouble matching this. Any help would be appreciated. One part that is giving me trouble is that it seems xlog prints out \r\n as \015\012 I am not able to successfully just pull out the "payloads" I have tried many different variations, however here is one of my latest: xlog("L_INFO", "[$ci] $(rb{re.subst,/^(.*)m=audio ([0-9]+) ([0-9 ]+)\015\012(.*)$/\3/s})"); Any help / input is greatly appreciated, thank you ahead of time! Happy 4th of July (for those who celebrate) Sincerely, Brandon Armstead

Outbound calls
by Alan 22 Jul '10

22 Jul '10

I'm trying to set up my account so outbound calls will go through a proxy: free.sipout.com:161 I've set it up under OTHER in my iptel.org account so I access pbxes.com and put free.sipout.com:161 into a trunk and set it as an outbound route. I then dial +001 area code and number but it doesn't work. What am I doing wrong? Thanks, Alan

Perl Code Execution via kamailio.cfg fails
by "Nicolas Rüger" 22 Jul '10

22 Jul '10

Hello, I try to execute some PERL-code within kamailio v3 for some research due to my thesis. I'm using debian lenny, kamailio_3.0.0 and perl_5.10.0. I added the follwoing lines to "kamailio.cfg": loadmodule "perl.so" modparam("perl", "filename", "/opt/kamailio-3.0.0/PERL/myperl.pl") modparam("perl", "modpath", "/opt/kamailio-3.0.0/lib/kamailio/perl") I added a subroutine called "myprint" to the file "myperl.pl" for testing. I tried to exec the subroutine by adding the following line to "kamailio.cfg" just before "Routing Logic" (...even tried within "route{..}") as described in the perl_module description : perl_exec_simple("myperl"); Unfortunately it seems the code isn't executed, as it should write some lines in a log-file. What can I do? Thank you!! Cheers Nicolas additional information: ======================= Kamailio is starting without problems it just shows the follwing warning: "0(28679) WARNING: <core> [sr_module.c:445]: /opt/kamailio-3.0.0/lib/kamailio/modules_k/perl.so: exports dlflags interface is deprecated and it will notbe supported in newer versions; consider using mod_register() instead 0(28679) DEBUG: <core> [mem/f_malloc.c:265]: fm_malloc_init: F_OPTIMIZE=16384, /ROUNDTO=2048" -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT!

The value counts three times, as several retries are done from the driver before it gives up. "The values counts 3 times" this was my issue, as I was adjusting the value between 10, 20, 30, 60, 120, and having inconsistent table load times from mysqld. After a reboot, mysql started performing better, more consistent with load times. My table with 800K records was taking between 30-38 seconds to load. With timeout_interval set to 10 (30 second timeout), I was right on the edge of the table loading or not loading, sometimes it would and other times it would not. So giving a bit of cushion on the timeout_interval seems to resolve the problem. Adjusting this value I could consistently reproduce the problem. So for large database tables, this timeout value should be set to about 1 second per 20K records. As far as the other issue goes with using pdt_list and pkg memory size, compileing mi using system mem solved this issue as well. Also pdt_list has the option to search for prefixes which works in my case without the need to increase pkg memory or system memory: sip-router2:~# kamctl fifo pdt_list . 99999 PDT:: SDOMAIN=* PREFIX=999990 DOMAIN=2 PDT:: SDOMAIN=* PREFIX=999991 DOMAIN=2 PDT:: SDOMAIN=* PREFIX=999992 DOMAIN=2 PDT:: SDOMAIN=* PREFIX=999993 DOMAIN=2 PDT:: SDOMAIN=* PREFIX=999994 DOMAIN=2 PDT:: SDOMAIN=* PREFIX=999995 DOMAIN=2 PDT:: SDOMAIN=* PREFIX=999996 DOMAIN=2 PDT:: SDOMAIN=* PREFIX=999997 DOMAIN=2 PDT:: SDOMAIN=* PREFIX=999998 DOMAIN=2 PDT:: SDOMAIN=* PREFIX=999999 DOMAIN=2 Using the list prefix search option will pipe out about 10,000 records, but errors out with "no more pkg mem" past that. Thanks for all your input on this thread to help me isolate the issue. JR -- JR Richardson Engineering for the Masses

Hi Guys, I have 2 kamailio servers. I need to load balancing for this 2 kamailio servers.
