Guys may be litte OT,
But for some new members info might help:
Basic Voice in Cisco:
VoIP:We are using analog phones and router encapsulate voice packet within data packets. Routers must have fxs/fxo ports and in there is no CCM(Call manager in voip)
IP telephone:We are using IP phones and we have to use CCM, call manager software in a server(compaq or cisco) to define route patters, dhcp etc. In ip telephoney, phones must have ip address assigned(static or dhcp)
So VoIP is different than IP telephney(Must have cisco call manager). Guys I think this must be a basic info. If anybody disagrees, please tell this board.
thanks

Call Manager Express.
A Cisco Call Manager (CCM) like call control system that is a feature
for some routers and some IOSs. I.e. an all in one solution for your
branch if you also go with UnityExpress (also a Unity inside a NM, i.e.
Network Module).
