Hi ,

You can refer the link for VIC/FXO  cards support on ISR series ?

You have 4xHWIC slots on that router which supports VIC cards also. So yes - you can put 2xVIC2-4FXO and connect your 8 PSTN lines with it. Just remember to check if you have enough DSP resources for this and adequate IOS on platform which supports voice ;)

BR,
