[SR-Users] Question about LCR ping option
Hello I am using kamailio 1.5.2. Our kamailio server has multiple IPs, and 1 of them happens to be a private IP for management purposes. When enabling the ping feature of the LCR module the machine sends the OPTIONS messages from the private IP. I need it to use at least any of the public IPs and if I can specify it it would be even better. I tried using the directive ping from with one of the public IPs but it only uses it to populate the From header, not to send the message from. One option could be to configure the configuration file with the listen directive including only the public IPs. However, there are more than 50 IPs, is there a limit to the number of IPs? I tried with a subnet and it is not allowed. Is there any other work around? txs a lot fborot ___ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
Re: [SR-Users] Question about LCR
There is nothing wrong with the carriers, so I wouldn't want to mark them. Just no route to destination type scenario. I like daniels option with the drop on_branch. Only challenge I have is keeping a list of all the flags I have already tried. Say I have five carrier groups and I set the flags in gw to 1 2 3 4 or 5 respectivley. How could I use an AVP to efficiently keep a running list and then check against that list? Thanks!

[SR-Users] Question about LCR
Hello,
I have a question about LCR which I have been unable to solve. I have 4
upstream carrier gateways owned by 2 carriers. Each carrier provides a
primary and secondary gateway for load balancing purposes. On a 5XX error I
am trying to send the same call to the other carrier. If both carriers
reject the call with 5XX, I allow the response to go downstream to my
asterisk server. The issue I am running into is that in a scenario where
both my carriers respond with a 5XX, I end up presenting the same call to
all 4 gateways. I would like to present the call to one gateway on each
carrier and not try the same carriers second gateway for the same call.
Here is what is happening now:
ASTERISK -- INVITE -- KAMAILIO
INVITE -- CARRIER A/GATEWAY 1 -- 5XX Error
INVITE -- CARRIER A/GATEWAY 2 -- 5XX Error
INVITE -- CARRIER B/GATEWAY 1 -- 5XX Error
INVITE -- CARRIER B/GATEWAY 2 -- 5XX Error
KAMAILIO -- 5XX Error -- ASTERISK
OR any combination of the above... i.e.
ASTERISK -- INVITE -- KAMAILIO
INVITE -- CARRIER A/GATEWAY 1 -- 5XX Error
INVITE -- CARRIER B/GATEWAY 2 -- 5XX Error
INVITE -- CARRIER B/GATEWAY 1 -- 5XX Error
INVITE -- CARRIER A/GATEWAY 2 -- 5XX Error
KAMAILIO -- 5XX Error -- ASTERISK
What I want to happen is:
ASTERISK -- INVITE -- KAMAILIO
INVITE -- CARRIER A/GATEWAY 1 or 2 -- 5XX Error
INVITE -- CARRIER B/GATEWAY 1 or 2 -- 5XX Error
KAMAILIO -- 5XX Error -- ASTERISK
I tried dealing with the issue using some flags on the gateway, but i
couldn't get the logic to work properly. Here is the path I was heading
down, but my plan fell apart after some testing.
CARRIER A has a gateway flag of 1
CARRIER B has a gateway flag of 2
failure_route[1]{
$var(gw_flag) = $avp(i:712);
while(next_gw()){
if($var(gw_flag) != $avp(i:712)){
xlog(L_INFO,Found an LCR destination which is different
than current, routing. ($ci));
t_on_reply(1);
t_on_failure(1);
t_relay();
exit;
}else{
xlog(L_INFO,The next destination in LCR has the same AVP
flag, skipping. ($ci));
}
}
# let the reply go upstram - it is the default action
xlog(L_ERR, No Next Gateway - M=$rm RURI=$ru F=$fu T=$tu IP=$si
ID=$ci\n);
exit;
}
Any help would be greatly appreciated.
Thanks,
Geoff

Re: [SR-Users] Question about LCR
Hello,
I am not an extensive user of lcr module, but probably next_gw() adds a
branch each time is called in failure route.
If yes (when true you should see some parallel forking, depending o how the
addresses are selected), you can mark the bad branches with a branch flag
and drop them in a branch_route.
while(next_gw()){
if($var(gw_flag) != $avp(i:712)){
xlog(L_INFO,Found an LCR destination which is different
than current, routing. ($ci));
t_on_reply(1);
t_on_failure(1);
t_on_branch(1);
t_relay();
exit;
}else{
xlog(L_INFO,The next destination in LCR has the same AVP
flag, skipping. ($ci));
setbflag(10);
}
}
branch_route[1] {
if(isbflagset(10))
drop;
}
However, if the destinations are selected like provider 1, provider 2,
provider 1, provider 2, the condition you have in config file failure route
is not good, since you check for change of the provider in each step, which
happens in this case. Maybe you can use flags to check if a provider was
used (or avps).
Cheers,
Daniel
