I have 12 aastra 6731i phones a Trixbox 2.8.0.3. The phones are nat'ed on DHCP at the customer site. The Trixbox is hosted in our Datacenter. The customer's WAN IP is also on our network. All calls on the Aastra 6731i phones are dropping at 45:00. Calls have been tested with an aastra 6757i. Phones calls inbound or outbound on the aastra 6757i stay connected for 12+ hours until the call is terminated. A sip debug has been ran on the trixbox.
Is there a simple fix that is being overlooked?
The following error occurs before the originating call leg drops.
