Peer-to-Peer Numbers
Calls made between two IP clients without the intervention of a Proxy Server are defined as Peer-to-Peer Calls
(P2P calls). P2P call can be made from FXS or FXO port.
As the Peer-to-Peer call application does not require a SIP server, voice communication using this application is
done virtually free of cost. The major cost savings offered by this application makes it a very attractive mode of
inter-branch or intra-office voice communication.
Peer-to-Peer call applications can also be used by residential users for making overseas calls at no cost.
A maximum of 500 locations can be interfaced using ATA211.
To use this feature:
•
There must be a SETU ATA211 installed at each location.
•
The SETU ATA211 at each location must have a Static IP Address.
Let us take the installation scenario illustrated below as an example.
•
At both locations ATA is directly connected to the IP network.
•
At each location, you must do the following configuration:
•
enable a SIP trunk to be used for Peer-to-Peer calling.
•
set the SIP Trunk Mode to Peer-to-Peer.
•
configure the number callers must dial to reach this SIP trunk as its
SIP ID
.
•
set the
Incoming Call Routing
option on the SIP trunk as
Route to FXS
.
•
configure
Outgoing Call Route
on the
FXS
port.
•
configure
Incoming Call Routing
on the
FXO
port.
•
configure the Peer-to-Peer table.
The Peer-to-Peer table stores upto 500 entries. Each entry consists of the parameters Number, Name,
Minimum Digits, Maximum Digits and Destination Address.
•
In this example, you would have to configure the Peer-to-Peer table as follows:
•
At Location A, in the
Number
field of the Peer-to-Peer table, enter the Number you want to dial to
call the phone at Location B. In this case, 3001.
