Overview

Otter is a Toshiba Magnia SG20 server running Ubuntu Linux that acts as my firewall / router.

Goals

Replace a pricey $30 / month Packet8 phone with a more flexible system that allows me to use far cheaper services.

Planned set up

Incoming calls

[Grand Central] provides me with a free local phone number (DID) for incoming calls. They route the calls to a [Gizmo Project] SIP account.

I also have a [Freeworld Dialup] account that can receive calls.

Outgoing calls

Currently I have some money on account at Les.net. It's pay-by-minute with no monthly fee. Rates are about $.015

Another good provider is voipjet.com.

Hardware available

1 Grandstream Budgetone phone

1 Sipura SPA2000 ATA

1 Desktop running Ubuntu on the LAN with Gizmo Project softphone installed

1 Laptop running Windows XP on WiFi

Implementation

I am using the generic asterisk package that is pulled from the Ubuntu repository. To this I make the following configuration changes.

Les.net connection

Use the instructions with the les.net account to set up iax.conf and extensions.conf files.
