Matching Dial Peers
Match the calling type, then the router can associate the
called number with the incoming called-number.
Type is matched, router can associate the
calling-number with the answer-address.
Type is matched, the router can associate the callingnumber
with the destination-pattern.
Type is matched, the router can associate voice
port to port.
Call Completion
Using this same logic flow, the router could also match incoming calls from
the POTS to POTS dial peers.When configuring dial plans, you will need to
manually define them on the Cisco Routers using dialing peers. Dialing peers are
like static routes, helping the router make decisions on where calls can originate
and terminate, and what paths can be used.The attributes you configure will help
determine how the call is placed when the user dials their phone.
When used in conjunction with AVVID, a dial plan allows you to create your
network so it accommodates data and voice/video within your infrastructure.A
dial plan can be created in many different ways depending on the needs that arise
for each individual deployment.There can be plans that include redundant paths,
such as IP networks and the PSTN so any calls made have a path to completion.

AVVID Dial Plans • Chapter 9 283
You can incorporate abbreviated dialing, allowing offices to use minimal dialing
to complete intraoffice calls or even reroute calls. Or you can create call restrictions,
such as blocking 900 numbers.
NOTE
If you are implementing MGCP or SGCP as your calling agent, you do not
need to statically configure dial peers. If you are in an environment
where you are configuring multiple routers for your calling cluster, you
will have to configure the dial peers on all associated routers.
