System rock solid for 9 months then 5 days ago inbound calls get cut off after 30-40 secs. Have upgraded all modules but no change
Any ideas appreciated
Can you post any log file output that you have when a call is dropped? Who is your service provider? Is this over a SIP trunk or ISDN, etc?

Can you post your trunk settings please? Also have you made any changes to your firewall recently and do you have SIP ALG enabled on the firewall?
Lee hi no recent changes to the firewall plus checked SIP ALG is off please see below

Resolved, thanks for help, I discovered that the freepbx was using our back up ADSL connection rather than our main cable and the ADSL is not a fixed IP adddress
Glad to hear it!
