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.
