Thanks, Dimitry. That’s done it. Clearly my Google foo is bad today.

Subject: Re: [SR-Users] Setting source interface on relay

Hi Phil,

try using

force_send_socket(protocol:your_sending_interface:your_sending_port);

just before your route(RELAY).

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?
