Hi Khalil,


You will need to a have the following:


1- 3560-48-POE

this will be the access switches which will power your IP phones and connect your LAN,

You can connect then your PCs behind the IP phones which hace a port to the switch and another to the PC

Each switch is 48 port

So consider your needs.


2- Call manager

You can check on cisco which version will fit you needs

you can check this link


http://www.cisco.com/en/US/products/sw/voicesw/ps556/tsd_products_support_series_home.html


3- also it is better to have a 2821 router to act as your gateway

IT will support you having E1 to pstn and FXOs and FXSs and a unity express if needed

the ability to add PVDMs

It is the best one for this solution


For your 2-routers, please specify the exact models of them


Wish this be helpful :)

Hi Khalil,


You have three options for call control:


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.
