Re: [SR-Users] LCR next_gw() - certain GW, source from other IP address

Stagg,

While the Ips are the same, the suggestion to use “rd” along with an entry in the “hostname” column appears to be what I want.

I assigned in my DNS some testing hostnames to the single IP in question. When debugging, I see that rd contains the hostname, not the IP. I believe with that, I can differentiate between the two... And when I see hostname of blah.blah.tld, then go ahead and do the force_send_socket.

This definitely solves the issue for the time being. However, I am wondering if/when call volume increases if the call-setup time be delayed because of these look ups. Everything that I have read so far is that the gw_name is just information, the module doesn’t actually have access to it. Boo.

Same destination IP for both rate decks, so I need to go by something else, like the gw_name.

Do the provider gateways have the same IP address for the different rate plans? If the gateways are different then the following may be relevant.

       if (next_gw()) {
             # prepare for lcr failover
             t_on_failure("2");
             if($rd=="aaa.aaa.aaa.aaa")
             {
               xlog ("L_INFO", "This is a request for Some Rate Plan");
               force_send_socket(udp:xxx.xxx.xxx.xxx:5060);
             }
             else
             {
               xlog ("L_INFO", "This is a request for another rate

plan"); force_send_socket(udp:yyy.yyy.yyy.yyy:5060); }; route(2); } else { xlog("No gateways found!");

Hi there,

I have a requirement now that for one of my GW¹s in my LCR, needs to be sourced from another IP address (two different rate-decks with the

carrier).

...

This ratedeck will always be at least 2nd inline ...

I was thinking something along the sorts ... Some pseudo code:

failure_route [2] { . . if (next_gw()) { if ( name = 'gw_name') { force_send_socket(udp:ip.address.of.certain.ip:5060); } else { # just dummy, as we will send out our default IP for everyone else. } t_on_failure("2"); route(19); } . . . }

What variable will have the value that's in the gw_name column? I can't go by the IP address in $ru because the destination IP is the same between the two ratedecks.

Overall, Is that the best way to handle this requirement?

Thanks all,

-graham
