48.4. Example of IAX configuration

48.4. Example of IAX configuration
	Chapter 48. IAX - Inter-Asterisk eXchange

Figure 48.1. Configuration scheme

In the figure there are the following elements:

Site 1:
- IAX phone;
- PC with Zoiper program for IAX communications;
- Analog phone connected to a POTS port of the Abilis;
- Abilis that manages all the systems and a VPN with “Site 2”.

Site 2:
- Asterisk server;
- Analog telephone connected to a POTS port of the Abilis.
- Abilis that manages interconnection with Asterisk and a VPN with “Site 1”;

The purpose is:

To enable the communication between the IAX users (IAX phone and PC with Zoiper);
To enable the communication between the POTS telephone of “Site 1” and the IAX users;
To enable the communication between the IAX users of “Site 1” and the analog phone phone of “Site 2”;
To forward to the Asterisk of “Site 2” the calls sent to “Site 1” in case “Site 1” is busy or doesn't answer.

In this example, suppose that the POTS cards used to manage the analog phones and configured for Cluster and CtiLink for compressed phone calls, are already active on Abilis.

48.4.1. Configuration of the CTIIAX resource

Activate the CTIIAX resource in the Abilis of “Site 1” and enable up to 15 IAX connections.

48.4.2. Users configuration

Activate the two IAX users in the Abilis of “Site 1” (the IAX phone and the PC with Zoiper) and one IAX user in the Abilis of “Site2” (Asterisk).

48.4.2.1. “IAXPhone” user configuration

Add the user in the Abilis of “Site 1” and enable it to IAX :

	Tip

48.4.3. CTIIAX translation table

48.4.3.1. CTIIAX translation table of “Site 1”

Since we have specified the IAX-NUMBER parameter for the two IAX users of “Site 1”, the two routings will be automatically connected in the table.

48.4.3.2. CTIIAX transaltion table of “Site 2”

In the configuration of “Asterisk” user for Abilis of “Site 2”, we haven't specified any IAX-NUMBER, so the following chart will be empty.

48.4.4.1. CTI Routings of “Site 1”

The purpose is:

To connect the IAX users (iaxphone and Zoiper);
To connect the IAX users and the analog phone connected to the POTS on the Abilis of “Site 1”;
To connect the IAX users and the analog phone connected to the POTS of “Site 2”;
To forward the input calls of the ISDN line toward the remote Asterisk, in case the POTS telephone of Abilis is busy or doesn't answer after 20 seconds.

48.4.4.1.1. Communication between the IAX users.

The PR:6 routing routes toward port 101 (analog phone) the calls coming from the ISDN line (CTIP:34). In case the telephone is busy or doesn't answer after 20 seconds (T301:20), the call is forwarded to the next routing (NEXT:TRANSFERT).

The PR:7 routing routes the calls toward the Site 2 cluster; the numbers starting with 7 are sent to the remote Asterisk.

48.4.4.2. CTI Routings of Abilis of “Site 2”

The purpose is:

To connect the analog phone of “Site2” and the IAX users of the Abilis of “Site 1”;
To forward to Asterisk the calls coming from “Site 1” in case of the remote analog phone is busy or doesn't answer.

48.4.4.2.1. Communication between the IAX users and the remote analog phone.

Use normal routings for compressed phone calls:

The PR:1 routing routes to port ctip:101 the calls coming from any cluster and addressed to the number 320.

The PR:2 routing routes the calls coming from an analog phone to the cluster site1, when the called number belongs to the RemoteIAX list.

The PR:3 routing routes toward CTIIAX resource the calls coming from any cluster; when the called number starts with 7 the Ctilax routing table forwards the call toward to Asterisk.

Asterisk offers many options:

Answering service (saves the messages and sends them as mail enclosures);
Virtual answering service (in case the called number gives no answer, Asterisk sends a mail containing the calling number with data and time);
Operator service;
...

Tip

Asterisk offers many solutions of advanced call management (conference, answering service, operator service…); to every service you can assign a specific code and manage them with a single routing.

The PR:3 routing forwards to Asterisk all the calls starting with 7: Configuring the routing of the remote Abilis, the answering service can be assigned to number 701, the conferences to number 750, the operator to number 711, etc.

The calls converge toward this Abilis, the PR:3 routing allows the matching, and Asterisk manages the calls depending on the selected number.
