Hi there,

Yes it is a Gateway. I'm using internal to force traffic to 5060 tested as well external to 5080 still the same.

Context other VOIP Providers are working and users are able to register and do calls.
I had done recreating the Gateway by deleting adding it again, also did flushing and loading of XML and ACL.

Whats odd is that when first setting up it did the registration correctly and registered.
