Hi, good question. Not even the HW compatibility matrix mentions whic VIC are supported in the slots of the 37xx:


However, note the features available on AIM-VOICE-30 are not up to par with the latest DSP generation, so some people prefers to use a NM-HDV instead, that has PVDM2,

Hope this helps, please rate post if it does!

The AIM-VOICE-30 only supports E1 or T1 interfaces that are installed in the 3725 WIC slots. It cannot be used to provide DSP resources for the FXS or BRI ports.

Refer here for more details on the capabilities of the AIM-VOICE-30 module -


To support the combination of the BRI and FXS cards, you will need at least two voice cards such as the NM-HD-2V
