Re: [SR-Users] MTREE reload question

by Daniel-Constantin Mierla

Hello, the used size is pretty much the same after the reload, so doesn't look as leak. If you do 2-3 reloads is shmem:used_size staying around same value? It is clear boost in the fragments, I would say that after start the number of fragments is quite low, because it should contain the good records in memory as well. Btw, the version 3.3.x has options for defragmentation, see the core cookbook, you can enable it.

Memory allocation

by David

Hello, I originally asked this on IRC, but realized that this is probably better suited for the mailing list : If I set memory usage to 100mb ( -m 100 ) and set 100 children ( children=100 in kamailio.cfg ). Will Kamailio use 100 mb or 10, 000 mb ( 10 gb ) of memory ? Is the memory limit per child or global for kamailio ? Is there an MI command I can send to check what kamailio's health ? ( load, free memory, etc... ) ? Thanks, David

Rtpproxy re-INVITE handling

by Spencer Thomason

Hello, I'm using Kamailio 3.2.4 for NAT traversal using rtpproxy_manage() in a largely stock script. Everything works great until the far end (on a public ip) sends a t.38 re-INVITE. The 200OK from the NATed UAC then doesn't trigger rtpproxy and the private IP in the sdp causes the fax to fail. Any help handling these re-INVITEs would be greatly appreciated. I'm happy to post traces if that helps describe the situation. The network topology looks like this: NATed UAC -> Kamailio on a public IP -> UAS on a public IP Thanks in advance, Spencer Connected by DROID on Verizon Wireless

Example required for XMLRPC module.

by SamyGo

Hello, I recently posted email relating to using MI_XMLRPC for kamailio monitoring. As Daniel suggested and as mentioned in module docs Mi-xmlrpc is getting obsolete and don't compile on newer OSs. So I need to use XMLRPC module for pulling statistics from kamailio like get_statistics all: Please can anyone point me to some help other than module doc. I need a simple example script to pull data from kamailio and print it. Any help or pointers will be greatly appreciated. Thanks, Sammy G.

event_route[dialog:failed] and Warning "script writer didn't realese transaction"

by Uri Shacked

Hi, I started using testing the event_route[dialog:failed]. On my scenario, I receive an INVITE, use t_newtran(), check some stuff and send a failure reply like 3XX or 4XX. I use send_reply() and can see that the TM sends the reply. Now, if I use event_route[dialog:failed], I keep on getting the warning "script writer didn't release transaction". If I delete the event_route[dialog:failed] from the script, the warning does not appear. My solution was to work stateless, which is OK for this scenario. But, still, What does this event_route has that shows this warning? Why doesn't the transaction being released? (I tried to use t_reply as well and still the same). Thanks, Uri

Possible bug in authentication

by martian＠centrum.sk

Hello to everybody. I am currently working with Kamailio 3.3.1 on RedHat. The "loose_route" function was not working correctly and I observed some very strange behaviour (not as one described in the documentation of the function). I have found that there needs to be a port included in the "alias" variable for the loose_route function to work correctly. However, upon adding the port to alias, the INVITE messages were no longer authenticated (Kamailio just accepted them and didn't send proxy-auth header in 407 message). My alias: alias="domain.ch:5060" Examining default routing logic, I found the problem here: if (is_method("REGISTER") || from_uri==myself) { # authenticate requests ... } The "from_uri==myself" was no longer evaluated as true, because there was a port at the end of the alias. The FROM Header of the INVITE messages looks like: From: "acc1" ;tag=12345 ..so .. no port number there. Btw, I have fixed this with replacing the "myself" list with my own defined variable MY_DOMAIN. #!define MY_DOMAIN ".*(a)domain.ch" So now the condition looks like this: if (is_method("REGISTER") || from_uri=~MY_DOMAIN) { ... } I am not sure if this is a bug that needs to be fixed or not. I am just pointing my finger at it and I hope it will contribute to the development. Also, a valid description of this behavior (when using port in alias) would be appreciated. Cheers, Martin
