Years ago I did something similar (college instead of hospital) with 200+ analog lines using a Zhone MALC.
Originally I MGCPed them back to a Vocaldata/Tekelec T6000/Genband M6 and then converted them to SIP on a Broadworks switch.
The Zhone MALC was a bit of a pain to configure but became cookie-cutter once we got it working.
We installed it in a Zhone supplied outdoor cabinet in their very wet basement and included DC & batteries in a self contained system.
For cut over we did the following:
Existing Centrex lines from Verizon were terminated on a 'Centrex 66 block'
Existing College lines to the campus phones were terminated on a 'College 66 block'
Existing cross connects from Centrex block to College Block
We established new 'Crocker 66 blocks' with 25 pair Amphenols to the Zhone (disconnected)
We moved the cross connect from the centrex block and connected to the Crocker block. One at a time, mapping numbers to Zhone config
We created a temporary cross connect from Crocker block to Centrex Block
On the day of the cut over we pulled all of the temporary cross connects to disconnect Verizon from the campus and plugged the Amphenols into the Zhone.
200+ phones cut over in under 10 minutes.
I think the MALC is EoL'd but the Zhone MXK is basically the same thing.
You can also do this with Adtran TA5000s. or you can stack a bunch of Adtran TA924s
