wideband recording in Asterisk 1.8

Hi all,

I would like to know if something I am trying to do is possible.

I currently using 1.8 and would like to make recordings in wideband
(16khz)

I have an aastra 6739i which supports the g722 codec.

I made an agi application in which I would like an user to record a
promptlist.

I use the agi command record_file.

Which format setting do I need to be able to record in wideband?

Tried: wav, gsm, pcm. Nothing seems to give me the result I desire.

Hope someone can help me.

Kind regards,

Henry Dogger

  • I tried this also, but now I can’t listen to the prompts on my pc.
    On the phone it seems fine, but how do I know it’s wideband.
    G722 should be 16 khz 14 bit.

    I use goldwave to listen to the prompts, but this does not support such
    a setting.
    Can someone point me in the right direction perhaps?

    Perform the recording with G722 on your system (since that’s the audio
    codec you’re using)…Then use Asterisk’s “file convert” CLI command
    to convert to a more suitable format for your listening pleasure.
    Normally I’d suggest sox, but apparently sox doesn’t “know how” to
    work with G722.
