My PC is attached to the IP Phone and the IP phone is connected to a 4006 switch. My PC is on a separate VLAN as the IP phone. Started sniffer on my PC to capture sent and received traffic on my PC's NIC. Surprised to see that the sniffer trace contained voice traffic also. Do that mean the IP phone acts as a hub instead of a switch?
This reply is incorrect. The current IP phones have a 3 port *switch* (aka C3PO), with one port internal. They support 802.1q, have 4 queues (1P3Q1T), and prioritize CoS 5 traffic (voice) over data. CoS 5 traffic goes into the priority queue, all other traffic goes into queues 1-3. The queues are scheduled in round-robin fashion with a priority queue timer to make sure priority traffic gets out.
You are seeing traffic out both ports since one of the design goals was to be able to dual-home the phone for very high-availability designs. Check out CSCdr32892

the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
