Page 37: Security Profiles

A security profile defines whether the phone is nonsecure, authenticated, encrypted, or protected. Every Cisco Unified IP Phone that is supported by Cisco Unified Communications Manager Administration has a security profile. For information about configuring the security profile and applying the profile to the phone, see Cisco Unified Communications Manager Security Guide.
Page 38: Authenticated, Encrypted, And Protected Phone Calls

A protected call is established when your phone and the phone on the other end are configured for protected calling. The other phone can be in the same Cisco IP network or on a network outside the IP network. Protected calls can only be made between two phones.
Page 39: Security Restrictions

Cisco Unified Communications Manager System Guide. After you have set up the IP telephony system and configured system-wide features in Cisco Unified Communications Manager Administration, you can add IP phones to the system. To add Cisco Wireless IP Phones to the IP network, system administrators should conduct a site survey to determine strategic locations for access points (APs) to ensure good wireless voice coverage.

APs are critical components in a WLAN because they provide the wireless links or “hot spots” to the network. Each AP has a wired connection to an Ethernet switch, such as a Cisco Catalyst 3750 Series, that is configured on a LAN. The switch provides access to gateways and the Cisco Unified Communications Manager server to support wireless IP telephony.
Page 45: Radio Frequency Ranges

(1, 2, 5.5, 11 Mbps). Commonly called the Wi-Fi standard. 802.11d Enables APs to communicate available radio channels and acceptable power levels. The Cisco Unified Wireless IP Phone always gives precedence to 802.11d to determine which channels and powers to use.

Layer 3 roaming can be performed using intercontroller roaming or, if AP groups are used, to enable Layer 3 roaming. Layer 3 roaming with Cisco Unified Access Points is accomplished by controllers that use dynamic interface tunneling and requires Layer 3 mobility to be enabled. Clients that roam across controllers and VLANS can keep their IP address when using the same SSID.

Site Survey Verification, on page 44 AP Association At startup, the Cisco Unified Wireless IP Phone scans for APs with SSIDs and encryption types that it recognizes. The phone builds and maintains a list of eligible APs and uses the following variables to determine the best AP.
Page 55: Voice Qos In Wireless Networks

The wireless IP phone associates with the AP with the highest RSSI and lowest channel usage values (QBSS) that have matching SSID and encryption types. To ensure that voice traffic is handled properly, you must configure the correct QoS in the AP. For configuration information, see Cisco Unified Wireless IP Phone 7925 and 7926 Series Deployment Guide.
Page 56: Cisco Unified Wireless Ip Phone 7925g, 7925g-ex, And 7926g Administration Guide

Although 802.11b/g EDCF does not guarantee that voice traffic is protected from data traffic, you should get the best statistical results by using this queuing model. The Cisco Unified Wireless IP Phone marks the call control packets with a DSCP value of 24 and voice Note packets with DSCP value of 46.
Page 57: Cisco Unified Communications Manager Interactions

Implementing QoS in the connected Ethernet switch is highly desirable to maintain good voice quality. The COS and DSCP values that the Cisco Unified Wireless IP Phone sets do not need to be modified. To configure QoS correctly on the AP, see Cisco Unified Wireless IP Phone 7925 and 7926 Series Deployment Guide.
Page 58: Dynamic Host Configuration Protocol Server Interactions

DHCP allocates IP addresses dynamically and reuses IP addresses when devices no longer need them. If DHCP is enabled in the network, the Cisco Unified Wireless IP Phone uses the DHCP scope settings in the DHCP server to perform the phone provisioning bootup process. You must configure the settings of the DHCP server in the Cisco Unified Communications Manager network.

This client server security architecture encrypts EAP transactions within a Transport Level Security (TLS) tunnel between the AP and the RADIUS server such as the Cisco Access Control Server (ACS). The TLS tunnel uses Protected Access Credentials (PAC) for authentication between the client (phone) and the RADIUS server.
Page 61: Authenticated Key Management

EAP type. CCKM can optionally be used with WPA/WPA2/802.1x+WEP mode. Encryption Methods To ensure that voice traffic is secure, the Cisco Unified Wireless IP Phone supports WEP, TKIP, and Advanced Encryption Standards (AES) for encryption. When using these mechanisms for encryption, both the signaling Skinny Client Control Protocol (SCCP) packets and voice Real-Time Transport Protocol (RTP) packets are encrypted between the AP and the wireless IP phone.
Page 62: Ap Authentication And Encryption Options

• If AKM and 802.1x are used, the authentication method is LEAP. • The Cisco Unified Wireless IP Phone uses network EAP for 802.1x but you can enable open EAP. The following table provides a list of authentication and encryption schemes configured on the Cisco Aironet APs supported by the Cisco Unified Wireless IP Phone.

The phone cannot successfully start up until it connects to the LAN and registers with a Cisco Unified Communications Manager server. The following sections can assist you in determining the reason that the phone is unable to start up properly.
Page 233: Phone Cannot Connect To Tftp Server Or To Cisco Unified Communications Manager

IP phone may continually cycle while attempting to contact the identified TFTP server. The Cisco Unified Wireless IP Phone does not cache the IP information passed from the DHCP server, so the TFTP request must be sent and responded to every time the phone power cycles.
Page 234: Ip Addressing And Routing

Solution Verify the IP addressing for the Cisco Unified Wireless IP Phone. If you are using DHCP, the DHCP server should provide these values. If you have assigned a static IP address to the phone, you must enter these values manually.
Page 235: Cisco Unified Communications Manager And Tftp Service Status

Solution If the Cisco Unified Communications Manager service is not running, all devices on the network that rely on it to make phone calls will be affected. If the TFTP service is not running, many devices will not be able to start up successfully.
Page 236: Intermittent Network Outages

Verify DHCP Setup, on page 229. • Verify that the DHCP server is set up properly. • Verify the DHCP lease duration. Cisco recommends that you set the lease duration to 8 days. Voice VLAN Setup Errors Problem If the Cisco Unified Wireless IP Phone appears to reset during heavy network usage (for example, following extensive web surfing on a computer connected to same access point and switch as phone), it is likely that you do not have a voice VLAN or the appropriate QoS settings configured.
Page 237: Phones Have Not Been Intentionally Reset

Solution You can check if a Cisco Unified IP Phone received a command from Cisco Unified Communications Manager to reset by pressing Applications on the phone and choosing Administrator Settings > Status > Network Statistics.
Page 238: Ring Volume Is Too Low

• Check your gateway and IP routing for voice problems. • Check if a firewall or NAT is in the path of the RTP packets. If so, you can use Cisco IOS and PIXNAT to modify the connections so that two-way audio is possible.
Page 239: Phone Does Not Ring

• Check to see if noise or interference in the coverage area is too great. • Check that signal to noise ratio (SNR) levels are 25 dB or higher for acceptable voice quality. Cisco Unified Wireless IP Phone 7925G, 7925G-EX, and 7926G Administration Guide...
