NM-2CE1T1_PRI Support for voice requirements

We have a cisco 3800 series router with a 2CE1T1 module installed. We are trying to get a T1 supporting voice calls from an AVAYA switch up and operational. Is their a requirement for some DSP support as in the HDV module that we used previously for this to work. Do we need additional hardware.

3800 router supports Voice

NM-2CE1T1-PRI is Data card it won't support voice.

If you need to support voice (NM-HDV with a VWIC-1MFT-T1)

This Hardware will support voice
