Voice Interface Numbering in Cisco 3600 Series Routers
Voice interfaces are numbered differently from WAN interfaces described in the previous

interface type chassis slot/voice module slot/voice interface
If you have a four-channel voice network module installed in slot 1 of your router, the voice
interfaces will be:

Slot 1, voice network module slot 0, voice interface 0, referred to as voice 1/0/0 (closest
to chassis slot 0)
•
Slot 1, voice network module slot 0, voice interface 1, referred to as voice 1/0/1
•
Slot 1, voice network module slot 1, voice interface 0, referred to as voice 1/1/0
•
Slot 1, voice network module slot 1, voice interface 1, referred to as voice 1/1/1 (farthest
from chassis slot 0)
