Fusionpbx gateway not stable

[zaid.naeem]

I have configured freepbx extension in fusion pbx as gateway..almost 1 year it was running fine but now it is unstable and goes to unregister and fail_wait condition

Nice story.

Have you got a question?
What have you tried in resolving your problem?
What has worked or not worked?

I thought it was problem due to ip tables and access list.so I disabled them both.
When I do restart it is in registered state but after some mintues it goes to unreg or fail_wait state.
After every refresh gateway states changes
Continuously
