The MagPi: Build A Raspberry Pi Telephone Exchange

Earlier this week, The MagPi, the official Raspberry Pi magazine, published a how-to article on creating a wee PBX using a Raspberry Pi, RasPBX and a couple of SIP phones. They invite people to “Transform your humble home phone line into a feature-packed PBX with Raspberry Pi and Asterisk!”

I’ve been tinkering with Raspberry Pi for some while. It’s fun little platform. I’m actually awaiting the delivery of an Asus Tinker board so that I can explore the use of such an SBC that’s capable of UHD video output.

It amuses me that this MagPi article appears some 13 years(!) after I wrote How-To: Building an Embedded Asterisk Server for Tim Higgins at Small Net Builder.

Back then, there was nothing like the Pi, so I used a Soekris Net 4801. Being Intel-based, it could run a lightweight Linux-based OS and regular Asterisk distro. I used Astlinux, which was brand new at the time.

Everything old is new again. Except me, of course.

Tip of the hat to WhyADuck for pointing out this article.

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.

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.

Panasonic Launches New Range Of SIP Desk Phones

panasonic ucm_stg_cnt_051137-300 After a couple of years testing the SMB/SOHO marketplace with the KX-TGP5x0 SIP/DECT series Panasonic has today launched a new range of desktop SIP phones. There are initially three models in this new range, from the entry level KX-UT113 to the top-of-the-range KX-UT136 (pictured). List prices run from $120 to $270.

Compatible with Asterisk & Broadsoft’s Broadworks they seem to have all the features that you might expect, including POE and support for G.722 based wideband audio.

The support for wideband audio is nice. If anything like the earlier SIP/DECT models it’s a little limited because the devices are fundamentally designed around dialing by PSTN numbers, with no facility for handling SIP URIs.

I’ve always like the feel of Panasonic hardware. They got off to a rough start with the KX-TGP5x0 SIP/DECT series, but with the experience of Asterisk & Broadsoft certification behind them I would expect that by now they are now better positioned to address the SOHO market.

How To: HDVoice In PBX-In-A-Flash

I recently received an email from someone asking about enabling HDVoice in PBX-In-A-Flash.

I’m about to implement a PBXact for our small company, and I have a nicely running PBX in a Flash in my home. I’m wondering if I can HD-Audio-ize the home rig.

Here’s why I ask. We currently run a SIPX PBX in my company. Everything in that box, all the sound files, are all HD. When you talk to it with an HD endpoint, everything just talks HD. It’s a no brainer.

In my home PIAF/FreePBX/Asterisk, nothing is HD. How do I go about HD-izing it? I have the G.722 codecs all turned on, but I’m wondering if there is an easy way to make all HD-capable endpoints automatically talk HD to each other, and to talk HD to the PBX itself.

Any help is appreciated!

Thanks,

Joe

Since PBX-In-A-Flash is built upon Asterisk there’s a a good chance that this is possible, but its way outside of my scope. Given my employers migration to the OnSIP Hosted PBX I haven’t run Asterisk seriously for some time.
