Chapter 16 Configuring the Cisco Phone Proxy

Licensing Requirements for the Phone Proxy

•

Cisco Unified IP Phone 7941

•

Cisco Unified IP Phone 7941G-GE

•

Cisco Unified IP Phone 7940 (SCCP protocol support only)

•

Cisco Unified Wireless IP Phone 7921

•

Cisco Unified Wireless IP Phone 7925

Note

To support Cisco Unified Wireless IP Phone 7925, you must also configure MIC or LSC on the
IP phone so that it properly works with the phone proxy.

•

CIPC for softphones ( CIPC versions with Authenticated mode only)

Note

The Cisco IP Communicator is supported with the phone proxy VLAN Traversal in
authenticated TLS mode. We do not recommend it for remote access because SRTP/TLS is not
supported currently on the Cisco IP Communicator.

Note

The ASA supports inspection of traffic from Cisco IP Phones running SCCP protocol version 19 and
earlier.
