Asterisk on Raspberry Pi now has FXO, FXS and GSM Interfaces

The combination of Asterisk and Raspberry Pi harkens back to a time when I was seeking to run Asterisk on an small, embedded platform. I was a little ahead of the curve, seeking this before Digium released AsteriskNOW. I tried Michael Iedema’s Askozia PBX and settled upon Astlinux on a Soekris Net4801, which I used for a couple of years.

Of course, all this was before the now ubiquitous Raspberry Pi was released. It makes sense that someone would try that low-cost SBC as a host for Asterisk. However, there hasn’t been much hardware support for that effort until recently.

Today I read that SwitchPi is now offering modular and multi-port FXO/FXS interfaces, as well as a GSM interface.

  • OAK8X base module (4 onboard Asterisk FXO channels) $130
  • OAK8X base module with 8 channels (8 Asterisk channels, 4 FXO plus 4FXS) $180
  • OAK8X base module with 8 channels (8 Asterisk channels, 8 FXO) $180
  • PiGSM single channel GSM interface $99
  • PiTDM base module $89
  • PiTDM 2 channel FXO module $20
  • PiTDM 1 channel FXS module $10

This is exactly the sort of hardware I tinkered with when I was using Asterisk. I used a TDP400P card with FXS and FXO interfaces. I also used a SIP-to-GSM gateway, documenting the project in the early days of this site.

SwitchPi seems have started in January 2018. It’s good to see hardware support for running Asterisk on Raspberry Pi evolving and affordable.

Digium’s New Phones: Are They Truly Open For Business?

A few days ago on Digium’s blog Malcolm Davenport posted some initial details about the companies new line of SIP phones. Malcolm’s post presents our first formal glimpse into the relationship between the phones and a new module for Asterisk called the Digium Phone Module For Asterisk (aka DPMA.)

You may recall that various folks from Digium were on a VUC call back on Feb 3rd, not long after the phones were announced and shown at IT Expo.

En Route To Astricon 2011

astricon-reg-logo After much consideration I’ve found that I am able to attend Astricon 20011. I’m already committed to a series of meeting in Burbank, CA Monday-Wednesday, so I’ll be making a stop Boulder on the way home.

I plan on arriving late Wednesday evening and spending Thursday at Astricon before heading home Friday morning. Even one day will present a nice opportunity to meet up with folks that are normally only disembodied voices from a box on my desk.

If we manage to arrange a special VUC session for Thursday I’ll have the new Polycom Soundstation Duo conference phone along to help make the recording possible.

While I doubt that I’ll be hard to find, if you’re planning on attending and would like to meet-up drop me a note.

Asterisk 10 In SSSSuuuuuuuper-Wideband!*

While I am not currently an Asterisk user I still try to stay in touch with what goes on in that realm. Earlier this week Rod Montgomery penned a post at the Digium blog entitled “Top 10 Tricks You Didn’t Know That Asterisk Could Do.”

The post is structured like a Top 10 list. Most of the items included are genuinely useful. However, right at the bottom in the #1 position, he highlights newfound support for very high-sample rate audio, aka Super-Wideband.

Meta: New VPS Launched

hp-compaq-8510p-comp Not all progress is obvious without careful examination. Much of my time working on this site has, for the past week, revolved around getting the entire thing moved to a new virtual server…not that you would likely notice.

After some well documented effort (part 1, part 2 & part 3) to move from a shared host to a VPS, it ran well, essentially untouched, for over a year. UnmeteredVPS.net has proven a responsive and reliable hosting provider.

However, over that time there were a great many patches to the software (LAMP) that are the foundation of a WordPress installation. In July I found that something I wanted to do required updating PHP to a much newer version.
