Your logic is correct, you can either check the From: header or the
request URI or any other part of an incoming SIP message to make the
routing decision.
A simple example looks like:
if (is_method('INVITE'))
{
# check if from URI domain equals 911operator.com
if ($fd == '911operator.com')
{
# relay stateless using request URI
forward();
exit;
}
else
{
# relay statefull using request URI
if (!t_relay())
{
sl_reply_error();
};
exit;
}
}
