Asterisk
See also Otter
Overview
Bellman is a Via C7 Mini-ITX system running Ubuntu Linux that acts as my firewall / router.
Aug 08 I just upgraded from using Otter, a Toshiba Magnia SG20 server
Goal
Replace a $30 / month Packet8 phone with a more flexible system that allows me to use cheaper services.
It is working now!
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 used to have a [Freeworld Dialup] account but no one ever used it so when they went to a subscription service I let it expire.
Outgoing calls
I currently use Les.net for outgoing calls. I use their pay-by-minute with no monthly fee. Rates are about $.015
Another good provider is voipjet.com. I use them for my employer's business phone system.
Hardware available
1 Grandstream Budgetone phone
1 Sipura SPA2000 ATA (Can't find it. Geez my life is full of boxes of gadgets!)
1 Desktop running Ubuntu on the LAN with Gizmo Project softphone installed
1 Laptop running Windows XP on WiFi
1 Packet8 DTA-310, reflashed to be a Leadtek BVA8051. See http://www.voip-info.org/wiki-Packet8+DTA310+and+Asterisk and http://www.stromcarlson.com/projects/dta-310/
Implementation
I am using the generic asterisk package that is pulled from the Ubuntu repository. To this I make the following configuration changes.
Keep general changes out of main config files by using include files. In sip.conf add this line: #include sip-wildsong.conf and in extensions.conf add this: #include extensions-wildsong.conf
Grandstream phone
Add entries in sip-wildsong.conf and extensions-wildsong.conf
Edit the web settings for the phone.
Les.net connection
Use the instructions with the les.net account to set up iax.conf and extensions.conf files.
