Chapter 6 Configuring Voice over IP
Here are just a few of the things that you can do with these commands (which, as mentioned previously,
you set from config or config-dial-peer mode):

Dial-Peer Configuration Table
The next step in creating dial peers is to create a dial-peer configuration table. Under the following
headings, show data for all of your gateways and associated dial peers.
gateway-to-gateway scenario described earlier; your own will be far more complex.

Configure destination patterns with wildcards and other operators.
Example: Use to denote a 4-digit number beginning with 6.

Define fixed-length or variable-length destination patterns.
Use to denote a 4-digit number beginning with 6; use
Example:
6...
number beginning with 9.
Specify that a prefix be added to calls on certain outgoing POTS call legs.
Prepend 9 to calls that pass through a PBX requiring 9 to access an outside line; replace
Example:
prefixes that are stripped by a dial peer because they match the destination pattern.
Specify that certain dialed digits be expanded.
Expand local 5-digit extensions beginning with 7 to the full E.164 number 1-408-7xxx.
Example:
Create a hunt group to handle inbound calls.
Example: Establish multiple dial peers, each for a different voice port, and each containing the same
destination pattern; the gateway directs inbound calls to the voice ports in sequence until it reaches
one that is not busy.
Set up preferences for routing outbound calls.
Assign preference 1 to dial-peer voice 1, which directs outbound calls over the IP network;
Example:
assign preference 2 to dial-peer voice 2, which directs calls over the PSTN; the gateway, looking for
the longest exact match, finds both dial peers and then uses preference as a tie breaker among those
matches.
