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
Some time ago I received a Raspberry Pi B+ as a gift. It had been on my amazon wish list, and for good reason. It looked like one practical approach to emulating the venerable Logitech Squeezebox, which to this day serves as the basis for music playback hereabouts.
Since we were not expanding our music playback scheme there was at first little motivation to got ahead with this effort. That is, until the analog outputs of our existing fleet of Squeezeboxes started to fail. Eventually the analog outputs become unusable, the result of failing electrolytic capacitors. Three of our five SB3s now suffer this malady.
When stuff just works all the time it doesn’t often come up in conversation, which just seems wrong. After all, it’s still working! It’s the stuff that doesn’t consistently work that gets the attention.
We’ve used Logitech Squeezeboxes for musical playback around the property for a very long while. We presently have five of them deployed, including our original Squeezebox 3 that was purchased in 2005! In general they just work, which has been great, especially since they were discontinued years ago.
When we stage our annual Halloween festivities we are required to reposition some equipment. Last time around one Squeezebox powered-up with a fault in the analog output. One channel is delivered with level much reduced compared to the other channel. A quick search of the still lively forums.slimdevices.com turned up similar reports, attributing the problem to faulty capacitors in the analog output stage.
We now have three in service and two that have failed. Two failures over about eight years is completely tolerable. We remain committed to using the Squeezeboxen even if Logitech has discontinued the line.
