Good morning to all.

I am Valerio, and this im my first post.
I was never using OPENSER: I discovered it this morning, searcing for a solution.

I have this situation: I am using Motorola Canopy wireless antennas to deploy internet connection, but it implements a symmetric NAT which make not operating STUN protocol.
I think that one of solution should be to install a proxy server which redirects registering and calls to the public proxy (euteliavoip).
I thought that OPENSER should be a good solution: can you confirm this?
Thanks for every your suggestions.
Valerio
