Configuring Regional Parameters and Supplementary Services Localizing Your IP Phone 7 • Inband DTMF Boost: Controls the amount of amplification applied to DTMF signals. Affects only tones sent by inband method. Choices are 0, 3, 6, 9, 12, 15, and 18 decibels. Defaults to 12 dB. To support false detection, avoid inband and use OOB. With OOB, the DTMF Playback Length does not matter. If you use inband, use a smaller DTMF Boost value. To get better detection by the IVR, avoid inband and use OOB. This way, the DTMF tone is reconstructed by the PSTN gateway or the remote endpoint, and the quality is not subject to distortion from the audio codec. If you use OOB, use a slightly longer DTMF Playback Length. If you use inband, use a higher Inband DTMF boost. NOTE On the Cisco SPA525G2, when using the Mobile Link line (through the Bluetoothenabled mobile phone), the local user can hear a double tone (echo) when pressing digits (DTMF tones) and engaged on a call. This can happen with certain mobile phones that have the option to play locally the local tone (which is also played by the Cisco SPA525G2). This does not affect operation with interactive voice response applications, as the tone is audible only on the local device. See the Cisco support community at http://www.cisco.com/go/smallbizsupport for phone compatibility information, and also consult the latest Cisco SPA525G2 release notes, available at cisco.com. Localizing Your IP Phone The following table describes the localization parameters in the Miscellaneous section. Field Set Local Date (mm/dd) Set Local Time (HH/mm) Description Enter the local date (mm represents the month and dd represents the day). The year is optional and uses two or four digits. For example, May 1, 2008, can be entered as: 05/01 or 05/01/08 or 05/01/2008. Enter the local time (hh represents hours and mm represents minutes). Seconds are optional.
