Hello Iñaki,
Hi Inaki,
Hi all,
you should ask Alexandr he has introdused this feature with rev5452, but I'm not sure if he is on the lists all the time, so I'll forward your question to him...
sorry, I am currently offline and couldn't answer directly to the list.
anyway. I agreed, 180 seconds it's too big ping interval, but it couldn't be also less 32 seconds.
http://www.ietf.org/rfc/rfc3261.txt
17.2.2 Non-INVITE Server Transaction
T1 = 500 ms.
Timer J 64*T1 for UDP Section 17.2.2 Wait time for 0s for TCP/SCTP non-INVITE request
so, the timer for "completed" is 32 seconds and couldn't be less.
of course, you can use less value, but on own risk :-) RFC 3261 are not recommendet it :)
Thanks for pointing it out. However, if a gw takes so long time (~32 seconds) to respond I prefer to consider it as "offline" :)
don't forget to disable ping for this gateway, because finaly you will have a DDOS effect of the "offline" gw. :-)
Well, If the host is already offline then it doesn't matter to kill it more XD
Thanks.
Hello. I was reading this thread and it seems to me very interesting. In fact, I was looking for a parameter that would let me mark a gateway as down and then avoid the LCR module keep sending calls to it. So just to clarify this topic. If I'm using Kamailio 1.5.1 with LCR in front of several gateways, and one of them goes down. The gateway is marked as down? Isn't? What parameter controls the "ping" to the gateways?. Can I set a gateway down manually?. I'm using "fr_timer" to 3, is this a problem?
Thanks in advance.
Regards, Ricardo Martinez.-

If I'm using Kamailio 1.5.1 with LCR in front of several gateways, and one of them goes down.
The gateway is marked as down?
Yes (if it was the appropiate value in the table).
Isn't? What parameter controls the "ping" to the gateways?.
The field "ping" in "gw" table.
Can I set a gateway down manually?.
You can modify the table and then reloading the gws with a MI command.
Hello Iñaki. Thanks for your answer. So, what values can take the "ping" paramenter in the table? I mean ... 0 is up? 1 is down?.. or something like that? Is there a way to automatically mark a gateway as down?... maybe a constant ping to the gateway?.
Thanks again.
Ricardo.-

As far as I remember (but please check the module doc), 0 means down, 1 means up, and 2 means "no ping" (no monitorized).
Thanks again.

Thanks... i can't find anything in the docs... What about the second questions?. Can I mark a gateway as up/down automatically via a configuration parameter?. For example if the GW did not answer an INVITE or a ICMP could the script mark the gateway as down? Thanks Ricardo.-

LCR itself will mark the gw as down and willmark is as up again when it's active. For this, you configure, in LCR module, which SIP response codes are required for both cases.
