Hi,
Thanks for the reply,
Could you provide me the example script for stateless forwarding of
invite when a call is received from say a 911 operator to the server?
I suppose this should be implemented by checking the From field of the
invite and if it is from a certain 911, then it should be forwarded
statelessly (or is this logic incorrect?). I am new to the Openser
stuff, so I do not wish to change the script myself.
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;
}
}
Please always CC users(a)lists.openser.org so that others can take
advantage of the discussion.

Hi all,
Can any one tell me if the same running instance of Openser can be
configured as a stateful proxy for some user accounts and for some
numbers like emergency services, it acts like a stateless proxy, just
forwarding the request to the destination?
Yes, it only depends on what forwarding function is used in the
routing script:
- t_forward(..) --> stateless
- t_relay(..) --> stateful
