Is there an easy way to figure out on which server a uac is registered when
using a shared database (modparam("usrloc", "db_mode", 3)).
When uac1 is registered on server1 (dns srv loadbalancing) and uac2 is on
server2. A call from uac1 to uac2 with a simple lookup("location") will result
in server1 directly trying to connect to uac2. If this device is natted (or
behind a stateful firewall) this will fail.
In the location table the column socket contains the server which received the
request. So if I know this value I can have server2 route the call to this
value/server and have the call delivered to uac1 via an "existing connection".
The idea was to use reg_fetch_contacts to fetch this/these socket values in
$ulc and in case they are not local redirect/branch to those servers. But if
the value of socket isn't local the $ulc for socket is null.
I could use sqlops to fetch this manually, but is there an easier way I am
missing?
