Just to complete with a bit more details that should be useful for
people not familiar with the topic -- as force_send_socket() takes only
static string parameter (perhaps we need to change that), you can do
assignment to $fs variable for getting the same feature.
Also, in most of the deployments where the linux doesn't have routes for
bridging the network interface, you may get along with setting core
parameter mhomed=1
When Kamailio acts as a presence server, NOTIFY requests are generated
by kamailio and don't get in request_route, for that you have to use
event_route[tm:local-request].
Cheers,
Daniel

Hi Phil,
try using
*force_send_socket(/protocol/:/your_sending_interface/:/your_sending_port/);*
* *
just before your route(RELAY).
Best Regards

*Betreff:* [SR-Users] Setting source interface on relay
Kamailio receives a fairly arbitrary out of dialog NOTIFY on an
interface with a private IP address (eth1). It runs it through the
following code which relays it to an IP/port combo pulled from a hash
table.
The IP that it is relaying to is a public address and should be
addressed out of the interface with a public IP address (eth0). It is,
however, sent on the private interface (eth1) and thus never reaches
its target.
route[PHONEREBOOT] {
# Only handle check-sync (Polycom) NOTIFY
if (!is_method("NOTIFY") || $hdr(Event)!="check-sync")
return;
# Look up ip:port combo in the agentloc hash table
if ($sht(agentloc=>$rU)==$null)
return;
# Set SIP URI to point to the agent
$ru = "sip:" + $rU + "@" + $sht(agentloc=>$rU);
route(RELAY);
exit;
}
Is there a way to explicitly set the source interface to relay on?
Thanks
