[cisco-voip] MRA calls dropping

[Kent Roberts]

We saw this with people that had internet options that weren’t the greatest.        To help resolve we adjusted a timer, and actually enabled/changed a FW port.   Both made a huge difference.     However I don’t remember if we were getting drops based on bye, or timeouts resulting in the bye.  Its been a while.   But I can get the info if you like.
