...ble with the femtocell and could be roof mounted. Once WiFi calling became available, Sprint dropped support for the femtocell. So I added a Trimble RES 360 Carrier Board and Rpi2 and created a Strata I time server. In July of 2017 a lightening strike took everything out (despite the lightening arrestor) so I migrated to RPI3 with a GPS Networking L1GPSA-N L1 Roof Antenna. I split the GPS signal and have two RPI3s each with a Trimble RES 360 Carrier Board. Since I already have this hardware providing approximately 1uS time accuracy (wouldn't want to be late for dinner), I thought I might t...

A few months ago, I built a samba 4 DC on a RPi 2B v1.1 with Louis' packages. It's just like a normal Intel cpu based installation with a couple of minor exceptions. I built mine on Raspbian Lite. You'll have to add an additional user and give it sudo privileges.The network setup was like the older Debian 9 by simply adjusting /etc/network/interfaces. To add Louis' repo

I am located in the UK, and I am using Sipura spa-2000 adapters to connect analog phones to a voip network. The network connects to the PSTN as well via the Sipura spa-3000 adapter. I would like to provide surge protection for the spa-2000 and the spa-3000 adapters. 1. For spa-2000, fxs port: What is the maximum tip-to-ring voltage before damage to the the adapter occurs? 2. For spa-2000,

Guys. I know there are wifi sip phones out there but I have a question, are any of these phones "anti explosive"? By that I mean, there are certain regulations about phones or cel phones that are not recommended to operate in environments like gas stations due to sparks and the chance of ingiting gas fumes. Are there any wifi sip phones out here that have complaince with regulations to
