A. No. The Cisco Unified Wireless IP Phone 7920 does not have support for call preservation when roaming between Layer 3 networks. The Cisco Unified Wireless IP Phone 7920 drops the active call and then goes through the process of authenticating, associating, and obtaining a new IP address before it can register with the Cisco Unified Communications Manager server again.
