E1 PRI bearer capability

Is there a way to set the bearer capability? My carrier needs it to be set to 3.1KHZ audio instead of speech something like this.

Instead of this:
Bearer Capability (len= 5) [ Ext: 1 Q.931 Std: 0 Info transfer capability: Speech (0)

I should send this:
Bearer Capability (len= 5) [ Ext: 1 Q.931 Std: 0 Info transfer capability: 3.1kHz audio

Im currently using a TE410P w/o echo canceller. My Asterisk version is 1.4.25 and my dahdi is 2.1.0.4

TIA

hello:
please try to use: SetTransferCapability()
good luck!
