Cisco Unified IP Conference Phone and Cisco Unified Communications Manager Interaction
Cisco Unified IP Conference Phone and Cisco Unified Communications Manager Interaction
Cisco Unified Communications Manager is an open and industry-standard call processing system. Cisco
Unified Communications Manager software sets up and tears down calls between IP devices, integrating
traditional private branch exchange (PBX) functionality with the corporate IP network. Cisco Unified
Communications Manager manages the components of the IP telephony system—the conference stations, the
phones, the access gateways, and the resources necessary for features such as, call conferencing and route
planning. Cisco Unified Communications Manager also provides:
• Firmware for conference stations and phones
• Authentication and encryption (if configured for the telephony system)
• Configuration file using the TFTP service
• Conference phone registration
• Call preservation, so that a media session continues if signalling is lost between the primary
For information about configuring Cisco Unified Communications Manager to work with the IP devices
described in this chapter, see Cisco Unified Communications Manager Administration Guide, Cisco Unified
Communications Manager System Guide, and Cisco Unified Communications Manager Security Guide.

Cisco Unified IP Conference Phone and VLAN Interaction
When Voice VLAN (VVLAN) is disabled, the egress SW port packets are not tagged and only untagged
packets are accepted on the ingress direction.
When VVLAN is configured as 1-4094, the egress SW port packets are tagged with the VVLAN. For ingress
packets, if VLAN is different from VVLAN, only the packets that match the VVLAN are accepted. If VLAN
equals VVLAN then both packets that match the VVLAN and untagged packets are accepted.
When VVLAN is set to 0, 802.1p is enabled. The egress SW port packets will be tagged with 802.1p. On the
ingress side, both 802.1p tagged packets and untagged packets are accepted.
