I encountered a weird problem on our Asterisk Server sometime our established iax trunk to our provider suddenly became UNKNOWN on status. However upon issuing the reload command on the asterisk CLI it corrects itself because it forces the IAX to re-associate itself however I have no idea why is that happening since upon checking the logs I did not found anything weird.
Any advice on this would be very appreciated
