CAUTION
Service Interruption
The Media Card 32-port trunk card does not support
Profile 3. If Profile 3 is provisioned, the card is unable to
make or receive calls.
The DSP Profile values appear. See Figure 98 "DSP Profile sub-tabs
– Profile 1 Options sub-tab" (page 308) .
Some of the values that can be changed are:
• DTMF tone detection – for voice mail access and IVR, for
example. Allows DTMF tones to be reliably transmitted across
the network. See
"DTMF Through Dial" (page 69) .
• Enable echo canceller – enables echo in calls, on by default
• Echo canceller tail delay – by default, the value is 128 ms
• V.21 fax tone detection – allows fax calls to be transmitted as
data and not as voice packets. When the fax call is transmitted
as data (T.30), the call has a much greater chance of success.
