Calls disconnect after 8 - 10 minutes

Hi All,

I am having a problem on ISDN lines disconnecting randomly after about 8 minutes on a active call.Most of the time it disconnects after 9 minutes and 56 seconds.... really strange?

I ran a debug isdn q931 and recieve the following error on disconnect.

Q931: Ux_DLRelInd: DL_REL_IND received from L2

I am using 2 BRI's for outgoing and incoming calls.

I have tested this with other ISDN lines just to make sure the problem is not on the Telco side. I have also used 2 UC500, having the same problem on both.

Any help will be appretiated!
