Configuring the PA-VXA, PA-VXB, and PA-VXC
Using the elements, the algorithm is as follows:
This algorithm shows that if a value is not configured for answer address, the origin address is used
because, in most cases, the origin address and answer address are the same.
To configure DID for a particular POTS dial peer, use the following commands, initially in global
configuration mode:
Command
Step 1
dial-peer voice number pots
Step 2
direct-inward-dial
Note
Direct inward dial is configured for the calling POTS dial peer.
Configure VoIP Peers
VoIP peers enable outgoing calls to be made from a particular telephony device. To configure a VoIP
peer, you need to uniquely identify the peer (by assigning it a unique tag number) and define its
destination telephone number and destination IP address. As with POTS peers, under most
circumstances, the default values for the remaining dial-peer configuration commands are adequate to
establish connections.
To enter the dial-peer configuration mode (and select VoIP as the method of voice-related
encapsulation), use the following command in global configuration mode:
dial-peer voice number voip
The number value of the dial-peer voice voip command is a tag that uniquely identifies the dial peer.
To configure the identified VoIP peer, use the following commands in dial-peer configuration mode:
Command
Step 1
destination-pattern string
Step 2
session-target
{ipv4:destination-address |
dns:host-name}
OL-3592-02
For all peers where call type (VoIP versus POTS) matches dial peer type:
if the type is matched, associate the called number with the incoming called-number
else if the type is matched, associate calling-number with answer-address
else if the type is matched, associate calling-number with destination-pattern
else if the type is matched, associate voice port to port
Purpose
Enter the dial-peer configuration mode to configure a POTS peer.
Specify direct inward dial for this POTS peer.
Purpose
Define the destination telephone number associated with this VoIP
dial peer.
Specify a destination IP address for this dial peer.
