SNMPStats and multiple proxies
by Antanas Masevicius 30 Sep '11

30 Sep '11

Hello, been trying to run two sip-router proxies in parallel and to feed data from them to snmpd via agentx. But it looks like snmpd deamon directly routes snmp request just to one (probably first connected) proxy. What ways this can be solved? Currenly i am thinking like running two concurrent snmpd daemons binded to specific IP addresses. Is there a better way to do it? best regards, -- Antanas Masevicius

by Krishna Kurapati 30 Sep '11

30 Sep '11

Hi, When a user is removed using "kamctl rm", is there way way to clean up presence information in the database (xcap, presentity, watcher and active watcher tables) and in the cache? Is there a event that gets fired when the user is removed from subscriber table which I could handle in config file and and cleanup? Thanks Krish Kura

Re: [SR-Users] Placing ds_select_dst in kamailio.cfg, where?
by Daniel-Constantin Mierla 29 Sep '11

29 Sep '11

Hello, please keep the mainling list cc-ed. Calling ds_select_dst() first in the main route block is not really a good place. First you have to handle sanity checks, within dialog requests a.s.o. Of course it is a matter of your purpose, but as general hint, selecting the destination should be done just (or as close as possible) before relaying. If you take default config and you have only load balancing, then you can replace location lookup part with load balancing. Other parts may be stripped as well, just giving some direction here.

Hey again, Btw: I am using Kamailio 3.1.5 and found the event_route in 3.2.x Dispatcher documentation. Is there a possibility in 3.1.x?

simple question but can't find the answer
by JJ Zeng 29 Sep '11

Hi, I am really new to ser(just installed it today). My situation is here: Both A and B make tcp connection to ser proxy server. If A sends "Invite" to B, ser would look up the tcp connection of B, and relay the sip request. If B is not connected, then 480 is returned to A. When B sends back the response, ser would relay it to A. It looks really simple, but I just can't figure out how to do it. Thanks. JJ

OpenIMS
by Carlos Ruiz Diaz 29 Sep '11

Hello list. I'm trying to test/implement http://www.openimscore.org/ to setup an IMS scenario for development purposes. The project seems quite inactive to me and I wonder if there is any other similar project or this one just died and is no longer maintained. The documentation didn't specify if there is any kind of compatibility with Kamailio and based on what was written, only SER core architecture is supported. Any help will be appreciated. Regards. Carlos.
