For various reasons... no. It depends how extensive is the phone system you interact with normally, but (just random examples):
- if you pick up the phone at work, you can be marked unavailable on others' phones / local IM / ..., not so much on the mobile
- you have to pay for the connection you're making to your mobile (so basically paying for answering the call) - if you're somewhere where you can pick up a voip phone, that's not the case anymore
- during lunchtime, you could redirect people to an IVR "I'm at lunch - if it's urgent press "1", otherwise call be back in 15"
- you might not want others to call your mobile number directly (or you have a phone presence in another country, so the call goes through your pbx anyways)
- you can limit the noise in the office automatically if your phone doesn't ring when you're not there
- people calling you don't have to wait X minutes to find out you're really not there, and not running to the phone
There are many cool features, most of which you don't need really. But if your work relied phone communication 99% of the time, you could probably come up with 50 more points about what to do with this system.

Or I could carry a cell phone?
A very neat idea but, way over engineered.
