hello with my IP Phone

[richard pititto]

hello i have a 7940 cisco IP Phone and i have it plugged into my switch which is connected to a router and than to the internet and im a novice and am not sure how to get it work.  I tired to make a call from it and i get a busy signal and was wondering if there is something i have to configure or if its my internet service, im pretty sure it has VOIP, ive looked up information on the IP Phone and couldnt find anything about this problem but im sure its a simple one, any help would be great thanks just ask if you have anymore questions.

You need "something" for your 7940 to talk to.  A call server. 

You could get Cisco's CUCM, CME, etc. or you could research a free product called Asterisk.

What are trying to install CUCM on?

CUCM is a bit OTT for what you need.

Look at Cisco Unified Communications Manager Express (CME) which can be installed on a Cisco Router IOS.
