Dialpeer/Voiceport/BRI

js · ‎12-02-2009

Hello,

We have the following configuration:

interface BRI0/0/0
no ip address
no ip redirects
no ip unreachables
no ip proxy-arp
ip route-cache flow
isdn switch-type basic-net3
isdn point-to-point-setup
isdn incoming-voice voice
isdn static-tei 0

voice-port 0/0/0
translate calling 1
compand-type a-law
cptone NL

dial-peer voice 1000 pots
description Uitgaande gesprek ISDN
preference 7
destination-pattern 0T
progress_ind setup enable 3
direct-inward-dial
port 0/0/0

How do these 3 interact? The port 0/0/0 in the dial peer is the voice-port. That is something I understand, but when it comes to voice-port --> interface BRI I get a little confused. Does the voice-port 0/0/0 use the interface BRI 0/0/0? And voice-port 0/0/1 use interface BRI 0/0/1 etc?

I'm just trying to learn how these systems work.

Thanks,

Grant

Think of the voice-port as (more or less) the physical layer and settings for it. The Interface is the logical higher layers for ISDN Q921/931. The dial-peer is a mechanism to address traffic to a port or an IP address or another device, in this case any number starting with 0.
