The issue is in timing - specifically that GV starts counting when it senses the call, and your answering machine starts counting when it gets the first ring. If that first ring is delayed in coming through (say it ain't so Google), then the GV 25 second timer has a head start.
Assuming Rick's scenario is correct and I believe it is because other people have complained about GV delayed ringing, you can reduce the time it takes for your answering machine to pick up the call.
Verify this is the problem and determine approximately how long you have before GV VM answers the call by having the person call you.
Each ring last for 6 seconds (ring 2 seconds and silence for 4), so you need 18 seconds for 3 rings plus some time for the 4th ring to start. You can reduce the number of rings on the machine to 3, but now the it will pick up after 12+ seconds.
Another method is to leave it at 4 rings, but change the ring pattern on your OBi. This will give you more time to answer the incoming call.
This is the default ring pattern (Ring profile A/Ring Pattern 1): 60;(2+4)
Reduce the silence portion of the ring: 60;(2+3.7)
Now you have 17.1 seconds before the 4th ring starts.
Keep reducing the ring and silence until your answering machine picks up before GV.
