Note: The more I worked on this article, the more I realized that it needed to be split into two separate articles. There was more ground to cover here than I originally thought. This article covers configuring a travel router running OpenWRT as a gateway for an ATA, and a Cisco ATA. The Asterisk configuration stuff will come later.
As seems to happen during the time of the covid-19 plague, it's really easy to clear one's backlog of "wouldn't it be nice if" and household repair projects in a short period of time. I mean, hell, I recabled my server …
One of my holiday break hobby projects, a palate cleanser if you will, was reconditioning a classic Radio Shack touch tone dialer I'd picked up on eBay somewhen around Thanksgiving.

The SWAT team charged with the town of Lake Forest in Washington state was dispatched to the house of a local family after being informed that a heavily armed drug dealer had killed at least one individual and was in possession of a large stock of distributable drugs on the premises. As one would expect, they geared up for a full assault and hit the house like gang busters.
