Hi there,
I'm building an IVR application, for that purpose I've to use voice modem to send wav files over it.
When dialer dials the number, application automatically receives call, can detect digit pressed but unable to play wave file over telephone line.
Details of wave file which I'm using currently is as follow:

Bit Rate: 128 kbps
Audio Sample size: 16 bit
Channels: 1(mono)
Audio Sample Rate: 8kHz
Audio format: PCM

I'm using HIRO H50113, which is a voice modem and recommended by many experts for this type of application. Does anybody knows which frequency can be passed over this modem?
Thanks in advance.
