Hello ,
I am using a ISR4451 with an NIM-4E/M card. The router is configured with a 4 wire, type 5 voice trunk between an E/M port on the NIM and another router's E/M port elsewhere. The trunk is connected and is working properly.
On older routers (2811, 2911, 3945e, etc.) when the voice trunk was connected and when issuing the "show voice trunk-conditioning signaling" command, the output showed a line "last-RX-ABCD=0000 last-TX-ABCD=0000". On the ISR 4451, that line is missing from the output of the aforementioned command.
Is there something I am missing, a bug or CISCO just removed that info from the output of the "show voice trunk-conditioning signaling" command on the 4000 series???
IOS ver. is 16.02.
Thanks,
Narcis
