  • Page 28: Pre-Call Admission Control

    Pre-Call Admission Control If Call Admission Control (TSPEC) is enabled on the access point, the Cisco Unified Wireless IP Phone 7925G Series sends an Add Traffic Stream (ADDTS) to the access point to request bandwidth in order to place or receive a call. If the AP sends an ADDTS successful message then the Cisco Unified Wireless IP Phone 7925G Series establishes the call.

  • Page 29: Roaming Admission Control

    Roaming Admission Control During a call, the Cisco Unified Wireless IP Phone 7925G Series measures Received Signal Strength Indicator (RSSI) and Packet Error Rate (PER) values for the current and all available access points to make roaming decisions. If the original access point where the call was established had Call Admission Control (TSPEC) enabled, then the wireless IP phone will send an ADDTS request during the roam to the new access point.

  • Page 30: Roaming

    If the preferred band is not available, then the Cisco Unified Wireless IP Phone 7925G Series will try to use the less preferred band if available. If the phone roams out of coverage of the preferred band, where the less preferred band signal is available, then the phone will attempt to associate to that less preferred band.

  • Page 31: Multicast

    When channel parking is active, the Cisco Unified Wireless IP Phone 7925G Series will discontinue the scanning of the 5 GHz band and potentially roam to a 2.4 GHz neighbor, but also may stay on the currently connected 5 GHz AP if that is the strongest signal received.

  • Page 32: Ghz (802.11A)

    5 GHz (802.11a) The Cisco Unified Wireless IP Phone 7925G Series supports Dynamic Frequency Selection (DFS) and Transmit Power Control (TPC) from 802.11h, which are required when using channels operating at 5.25 - 5.725 GHz, which are 15 of the 23 possible channels.

  • Page 33: Ghz (802.11B/G)

    Design the network to accommodate the desired call capacity. The Cisco Access Point can support up to 27 bi-directional RTP streams for both 802.11a and 802.11g at a data rate of 24 Mbps or higher. To achieve this capacity, there must be minimal wireless LAN background traffic and radio frequency (RF) utilization.

  • Page 38: Dynamic Transmit Power Control (Dtpc)

    When using an access point that supports DTPC, set the client power to match the local access point power. Do not use default setting of Max power for client power on Cisco autonomous access points as that will not advertise DTPC to the client.

  • Page 51: Ssid / Wlan Settings

    The SSID to be used by voice clients can be configured to only apply to a certain 802.11 radio type. It is recommended to have the Cisco Unified Wireless IP Phone 7925G Series operate on the 5 GHz band due to have many channels available and not as many interferers as the 2.4 GHz band has.
  • Page 52 The WMM policy can be set to “Required” only if the Cisco Unified Wireless IP Phone 7925G Series or other WMM enabled phones will be using this SSID. If 7920 or other non-WMM clients will associate using this SSID, then ensure the WMM policy is set to “Allowed”.

  • Page 53: Controller Settings

    For the autonomous access point, ensure that the SSID is configured for open + eap as and network-eap when using 802.1x authentication. As of the 1.3(2) release, the Cisco Unified Wireless IP Phone 7925G Series utilizes open + eap when doing 802.1x authentication, but utilized network-eap in previous releases.
