[Flexisip-developers] Route to pstn

[Oz Mortimer]

Hi,
Is there a way to forward requests *to* no-registered users to another gateway? 
The requests will be from users registered to flexisip.
I want to achieve;
Calling from / to registered users handled by flexisip.
Calling to non-registered users (I.e. Pstn) to be handled by an external 
gateway.
I've tried the forward module, but that doesn't seem to behave as I would 
expect; it ignores requests to non-registered users, but forwards requests to 
registered users.
Thanks
Oz
