Beyondhing,

Hello,

What you describe can be an issue with a firewall closing down ports causing the call disconnect.  This happens often with some customers.  Please double check with your firewall administrator and ask if there are any timers set to around the 2 (180 seconds) minute mark.  If they have some ask if they can extend the timers out and test again.
