I plan to get the following

c3725-adventerprisek9-mz.124-16.bin with 64F/256M


2 Qty of NM-16ESW each with internal PPWR-DCARD-16ESW

The 3725 has an "integrated WAN Slot" so does that mean that I do not need to get a dsp for the VWIC as I plan to use the VWIC for Voice.

If I need to get dsp, do I assume a AIM-Voice-30 as the 3725 only has 2 NM slots as I want to use the internal AIM slot as I am using the 2NM slots for the 16ESW.

If I cannot get an AIM, can I use the NM-HDV for the VWIC-2MFT-T1 with a couple of PVDM?

You need to have DSP, because there are used every time you connect with a telephone interface.

Then, yes to all questions.

Hope this helps, please rate post if it does!
