You could get a 3845 and support up to 250 users. The 1800 will not support anywhere near as many people as you need for CME. You could squeeze into a 3825 CME, as it supports up to 175 users.
You could get CUCMBE, this is CUCM/unity connection in one box.
You could buy a full CUCM cluster, along with Unity. (this is probably too large for 160 users)
For hardware you will need a voice gateway with a PRI. This means you will probably need at least 1-2 PVDM2-64 for DSPs, you may want a VIC-2FXO for 911 emergency access, and probably a VWIC-2MFT-T1 for a T1 access. You could put this into your 1800 or 1700 as long as they are a voice capable router (1861 and 1760-V).
You would need to look into something like a 2811 with a NME-CUE.
As well, you would need to get the IP phones, PoE capable switches, and the licensing for all the above.
I would contact a local sales contact, and they will be able to give you the full information on all of this.
