as with any wholescale deployment there is going to be a cost and risks associated with doing this. you will be required to scrap all of the handsets you currently have in place and put some kind of ip telephone on everyone's desk. cisco phones would be a good option. they work very well with * and there are large quantities of them available on the 'grey' market (read ebay et al) so the cost is pretty good. Call Manager software isn't too expensive especially now that they have put a CM feature set into IOS and you can run it on a 2600 or above class router but * gives you flexibility and scalability that NO other system will give, so it is really unfair to compare it to CM or any other system for that matter. my advice on a project like this would be to just go in with your eyes open. Managing a pure VoIP network is different than the norm. you have to think about stuff like QoS etc. (you may need to upgrade some of those old hubs you have out in the maintenance facility right?). remember that most people look at the phone on their desk just like they look at the faucet in the bathroom and when they turn it to the left they expect hot water to flow and when they turn it to the right they expect cool water to flow and when it doesn't they scream bloody murder. if you are currently managing the * system your dept is using then you probably have at least the basic skills required to do this. just look at this deployment like the one you have already done with more phones sitting on it. your environment (govt.=no money/heavy requirements) is a fantastic use case for the rest of us. if you deploy this, make sure you post to the list your successes/pitfalls. it will give us all a stronger leg to stand on with our endevours. alternatively, go into the wiki and look for outside help, there are a lot of us out here trying to make a living doing this and we are all listed as consultants in there. Feel free to contact me off list for any more advice. or to tell me to piss off.
