dbaliases for ring groups, possible?
by Henrik Aagaard Sørensen 15 Jul '11

15 Jul '11

I've read somewhere about using dbaliases for ring groups. So I can call one number and several different numbers will then be called. The first to pick up the call gets it. I've tried to an alias in my dbaliases table in MySQL, but I can only make it possible to call different numbers for the same user. In a way the other way around then what I thought. Is it somehow possible to call one number and then having Kamailio call several different numbers /users? As I'm very newbee to Kamailio it would be nice with a more detailed answer, then perhaps just "Yes, use the module ...".

Call several different subscribers, first to pickup gets the call.
by Henrik Aagaard Sørensen 14 Jul '11

I'm new to Kamailio. Is it possible to have a group of subscribers (with different extensions) that you can call? And the first to pickup the call gets it.

topoh module - query about operation
by Pete Kelly 14 Jul '11

14 Jul '11

Hi I have been researching the topoh module which I understand is stateless and can persist across a server restart. >From what I can gather it does this by adding some extra, encrypted headers to the INVITE as it passes through the proxy- is this correct? If so, can I ask how it handles situations where the UAS does not resend these headers in subsequent requests? Pete

Syntax error - custom parameter
by Skyler 13 Jul '11

13 Jul '11

Hi all, I'm getting this error when using custom parameters and I don't why. when I use #!define WITH_ASTERISK the script throws the below error and when I remove the #!define WITH_ASTERISK the script loads without errors. I'm running kamailio-3.1.4-2.1.i386.rpm on Centos 5.6 Does anyone know why this might be happening? parse error in config file //etc/kamailio/kamailio.cfg, line 123, column 16: syntax error 0(2907) : <core> [cfg.y:3412]: parse error in config file //etc/kamailio/kamailio.cfg, line 123, column 16: unknown config variable 0(2907) : <core> [cfg.y:3409]: parse error in config file //etc/kamailio/kamailio.cfg, line 123, column 17-19: ERROR: bad config file (3 errors) kamailio.cfg::: lines 122-127 #!ifdef WITH_ASTERISK asterisk.bindip = "127.0.0.1" desc "Asterisk IP Address" asterisk.bindport = "5070" desc "Asterisk Port" kamailio.bindip = "209.15.226.21" desc "Kamailio IP Address" kamailio.bindport = "5060" desc "Kamailio Port" #!endif # This follows as described here: http://by-miconda.blogspot.com/2010/04/kamailio-30x-dyk-07-custom-cfg.html Thanks in advance

memory requirements for a registrar server
by Fabian Borot 13 Jul '11

13 Jul '11

Hello We are going to use kamailio 3.1.4 for a registrar server and need to know if the default parameters [shared memory and the like] is fine or if we need to plan in advance and increase it at compile time. If so, how should we proceed about it? For subscribers and location type of information, which memory type should we be more concerned about? private memory, shared memory, memory per process etc because it looks like some modules use shared memory others private memory etc. Also , I see that the command "kamctl fifo get_statistics all" gives info about memory used etc. How should we interpret the output like this: shmem:fragments = 24 shmem:free_size = 9665456 shmem:max_used_size = 23915072 shmem:real_used_size = 23888976 shmem:total_size = 33554432 shmem:used_size = 23648072 is this fifo function exported by a specific module? thank you in advance fborot

Header field manipulation
by Spencer Thomason 12 Jul '11

12 Jul '11

Hello all, Is it preferable to to a check before removing a header field or to simply call remove_hf()? Are there any performance considerations? i.e. if is_present_hf("X-Account-Code") remove_hf("X-Account-Code"); vs remove_hf("X-Account-Code"); Thanks, Spencer

Hi! Is there an easy way to disable the captcha? As siremis is an admin tool, not being public accessible (at least it shouldn't be) I want to get rid of it. Thanks Klaus

siremis 2.0 statistics problem
by Klaus Darilion 12 Jul '11

12 Jul '11

Hi! I just installed siremis 2.0. I did not let siremis update the SIP DB but did it manually (to sensitive) according to: http://siremis.git.sourceforge.net/git/gitweb.cgi?p=siremis/siremis;a=blob_… But when accessing some statistics, e.g. http://mydomain/siremis/ser/charts_tm/cg=tm I get an error: SELECT time_stamp,tm_active FROM statistics ORDER BY id DESC LIM... --> Unknown column 'tm_active' in 'field list' as statistics table does not have column "tm_active". Am I doing something wrong? Thanks Klaus
