Setting up IRLP Connectivity

In order to install IRLP connectivity on your ACID installation, it helps to be familiar with how IRLP nodes are installed in general. A lot of what happens with IRLP in your installation is similar to how IRLP preforms node installations and re-installations using their hardware.

A Note About Connecting to IRLP Reflectors

Some reflector owners do not permit Asterisk/app_rpt systems to connect to their reflectors, because Asterisk/app_rpt can cross-link audio from outside of the IRLP network. The safe thing to do is to lock out all reflector access. Repeated violations of reflector rules can get your IRLP PGP key revoked.

Setup

Both ACID and Limey Linux come with a setup script to install the IRLP binaries and scripts. The setup script can either perform a new installation, or an installation from a backup. To run the script type one of the commands below depending upon whether or not you are running Acid or Limey Linux

ACID


irlpsetup.sh


Limey Linux


irlpsetup


Follow the instructions and select NEW or REINSTALL You will be asked for some information about your node or where to read in the backup file.

If you are installing a new node. Run the script first and complete the installation before contacting IRLP for a new node number. Make a note of the stnXXXX number in the script and reference it when contacting IRLP. Additionally, after installation of a new node is complete, you must provide additional data by accessing a special “status database” web page from the public IP address of the system. See the IRLP owner's FAQ for details.

If you are re-installing an IRLP node, make a backup using the backup script in the scripts directory before running the IRLP install script on the ACID installation. Place the backup file in the /tmp directory and refer to it when the script asks for its location.

Setting Audio Levels to and from IRLP Systems

The audio gain going to and coming from the IRLP system may be set from within a Node Stanza as follows:

.
.
.
irxgain=-3.0      ; defaults to -10.0 db
itxgain=3.0       ; defaults to 10.0 db.
.
.
.

Use

From an app_rpt/Allstar node, IRLP connections look just like Allstar/App_rpt connections except the IRLP node numbers have been prefixed with a 4. For instance, if you want to connect to IRLP node 1234 on your app_rpt system you would dial *3 followed by 41234. As you can see we have reserved Allstar node numbers with a leading 4 for the IRLP number space.

For users originating from an IRLP node using IRLP supplied software, nothing changes for them, they just dial the 4 IRLP node number assigned to your app_rpt system and they get connected!
