The Trunk port between the router and switch had to be manually configured using sub-interfaces. Note, however, that the DATA vlan traffic and the phone VOICE vlan traffic for each host is carried over the same link (multiple vlan traffic over the same port). On this segment, the Trunk is formed automatically and is a special form of 802.1q trunk.
Step 6) Configure the Call Manager Express (CME) on the router
The image that is running on the router must support voice services. We are running ios c2800nm-advipservicesk9-mz.151-2.T2.bin in our lab. The output of show version command in Packet Tracer is:
