People still actually make phone calls? I mean its neat that you can run your own voip, but I struggle to imagine it getting used much or being worth even $5/month

I want to set something like this up myself, probably less for external calling than as an in-home intercom. Public dialing might be handy just so it can easily include cell phones.

(Author here.) Sadly its a lot less interesting: my home ISP still doesn't support IPv6.

For what it's worth, and if you're willing to tinker, you can get IPv6 for free through a tunnel as long as your router responds to ICMP: https://tunnelbroker.net/ You can get a bunch of /64s and a /48 for free because HE really wants everyone to have IPv6 available already. Picking the right internet exchange to route from and making Netflix not throw a fit requires some minor experimentation but I've found it to wo…

The SIP provider would also need to support IPv6 for this to do any good. voip.ms does not: https://wiki.voip.ms/article/FAQ#Do_you_Support_IPV6_with_SI...

Last time I tried Tunnelbroker, it caused major performance issues. Not sure it's a good thing for VoIP calls.

Cool to read someone indulge in this. For others interested with no prior context, also consider FreeSWITCH. Personal experience: I spent about 15 months working for a local telecom company, supporting their asterisk servers and developing interactive voice response applications. I was given the opportunity to build their residential voip service (in 2010?) from scratch and despite asterisk being so dominant I protot…

I took a look at freeSWITCH's site and it looks like they got bought out. Their documentation is a total mess because the acquiring company has imported lots of wiki pages without much care for how they fit together.

Their wiki has always been a bit of a mess. The company Signalwire is largely the same crew as the original FreeSWITCH team.

It's worth noting that Asterisk will run on very low-end hardware: for the last 7 or so years, I've been running a small Asterisk box on a VIA C3 Mini-ITX system. System idle power is around 10W. The only reason I chose the VIA C3 system over something newer was that a) I already had it and b) it had a PCI slot (specifically PCI, not PCIe).

The PCI slot let me plug in a Digium TDM800P and add eight POTS lines, either FSX or FXO, for pretty cheap.

Nice article. Is there a benefit to using a queue for incoming calls instead of just dialing multiple extensions with the & operator?

You get some statistics for queues but also for example you might want to only take one call at a time even if you can answer from multiple. Also Asterisk queues make it very easy to do things like 'there’s N callers waiting' etc.
