Cisco VOIP Question

[f510Yes]

Hello All
Do not have much information but, it seems the client has Cisco router based VOIP telephone system Version 3.x. They'd like to be upgraded to version 4. I am not sure what device this is exactly I have not been onsite yet. is this a router set up as a VOIP system? Or perhaps an appliance and what could this be?
They also are considering migrating from current router-based VOIP solution to a server based. Does Cisco manufactures software that can be installed on a Windows or Linux/UNIX system as opposed to their router devices running it? They also mentioned: CISCO MCH unified Communication services-7825 H2 Unified call manager appliance.
I will greatly appreciate any information
Thanks in advance to all
Regards
Sunden

The router platform on this is on a CCME Cisco CallManager Express. The server platform on the MCS-7825-H2-IPC1 server is what they need as a Publisher and another for a Subscriber. Software 4.1(3) is stable and 5.0 is out running Linux. Do they require voice mail? If so they need a Unity server as well.
