Hi Guys,

My Customer is trying active the ISDN in a router 2811 and we are found the following problem: The ISDN active the 03 levels, but, in the router don't appear the voice-port. I verify the configuration and it's Ok. The router is with version Version 12.4(23).

Any Idea?

Hi Bevilacqua,

I Believe that the IOS no is the problem, because we have the IOS simular in another equipment, but, that is 2821. I will continues found documentation in Cisco Site that explain that the module NM-1CE1T1-PRI don't have support to voice. Right?
