[SR-Users] sip domain

[David Villasmil]

One could also use dialplan and dispatcher, add the domains to the dialplan
table with the GID of the dispatcher, add all IPs to redirect to, and use
dispatcher instead. That would also give you failover and distribution.

In terms of multiple domains, there’s probably a better way, but this is
how I do it:

So I would add to the dialplan table the domains I’m serving to, I.e.:

Match *dom1* and attrs 1
Match *dom2* and attrs 2
...

Then on the dispatcher:

GID:1 ip: sip:1.2.3.4:5060
GID:1 ip: sip:2.3.4.4:5060
GID:2 ip: sip:9.8.7.6:5060
GID:2 ip: sip:8.7.6.5:5060

So anything with “dom1” in the $ru would be sent out to GID 1, “dom2” to
GID 2, and so on.

And use the dialplan and dispatcher like so:


modparam("dialplan", "db_url", "mysql://DB_USER:DB_PASS@DB_HOST/kamailio")

modparam("dialplan", "attrs_pvar", "$var(dispatcher_id)")

modparam("dialplan", "fetch_rows", 100)

...

route[DISPATCH] {

    dp_match("1", "$ru");

    xlog("[DISPATCH] '$ru' was translated to '$var(dispatcher_id)'\n");

    xlog("[DISPATCH] avp(dsdstid): $avp(dsdstid)\n");


        if(!ds_select_dst("$var(dispatcher_id)", "9"))

{

send_reply("404", "No destination");

exit;

}

xlog("L_DBG", "--- SCRIPT: going to <$ru> via <$du>\n");

t_on_failure("RTF_DISPATCH”);

      append_to_reply("Contact: <sip:$du>\r\n");

      sl_send_reply("300","Multiple Choices");

exit;

}


Or something like that. (I took this off my
https://github.com/davidcsi/kamailio-private-public/blob/master/README.md )

Please excuse and errors, typing on my phone :)

Hope that helps!
