Question
An engineer is configuring a PRI card on a Cisco ISR 4300 Series Router. When the engineer configures the voice PRI on the router, this error is received: "T1 0/1/0: No DSP resources to configure voice feature". Which action must the engineer take to resolve the issue if a PVDM card was installed in the motherboard?
Options
- AInstall the NIM card on a different slot.
- BReplace the memory slot in the motherboard.
- CReplace the flashcard, restart the router, and try it again.
- DInstall the PVDM directly to the NIM card.

Why each option
The error "No DSP resources to configure voice feature" indicates that the router cannot find or utilize the installed Digital Signal Processor (DSP) resources. Even if a PVDM card is installed on the motherboard, it needs to be properly installed onto the relevant Network Interface Module (NIM) card for voice features to function.
Installing the NIM card on a different slot would not resolve the lack of DSP resources, as the PVDM is not correctly positioned or detected.
Replacing the memory slot in the motherboard is unrelated to DSP resource availability for voice features.
Replacing the flashcard, restarting the router, and trying again is unlikely to resolve a hardware resource (DSP) detection issue.
For Cisco ISR 4300 series routers, PVDM4 modules are typically installed directly onto supported NIM voice cards (e.g., NIM-1MFT-T1/E1) rather than directly on the motherboard itself, to provide DSP resources for the voice features on that specific NIM.
