Few miles, as it is an U interface.


Check again with the manufacturer as NM-4B-U does not supports voice and they may not know what they're talking about.

No worries. When buying Cisco products, always make sure a reputable professional reviews everything before, because it's complicated stuff, and it's easy to make mistakes.

The voice modules have V in the part number, like VIC, WVIC.
