Hi,
My 7841 phones worked well with same configuration. I have two comments:
1) you have to choose mode east which is obvious
2) for voice register pool 1
Can you specify the specific subnet which exactly matches the IP Phone subnet, and you can create multiple pools instead of using one pool with big mask.

Sorry for that. Yes it is esrst :)
There is no option shown for simple srst under voice register global
