is ti 75 users total or only in UK ?
what is total user number ? all of them?
CUCME is good for under 200 users in one location, I think, but it depends on router used, check the Cioara;s Voice book for list. and CUCME is loaded onto router. so book lists c3900s routers support up to 200 users.
others may have more info on VoIP,
For voice mail you need AIM-CUE or larger capacity NM-CUE. The new CCNA Voice book is good start.
Thank you martin for your Quick reply. As always your answer is simple and to the point, makes things clear & easier to understand.
Its 75 users in UK and other 160+ across the world.
When you say CUCME is good for under 200 users, Does that means i have to get router with CUCME for every site?
Also, Do i have to buy licences to use soft phone?
