[OpenSIPS-Users] NATed REGISTERs are failing

[Bogdan-Andrei Iancu]

Hi Iñaki,

Keep in mind that SER started before RFC3261 :) - and there are a lot of 
things (like such params) that made sense in the pre RFC3261 world.
Now, I agree with your logic and I see no reason for having  
"reply_to_via=1"

Maybe we can remove this option to avoid any further issues like this one.

Regards,
Bogdan
