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 Bluetooth-
enabled 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.
