@bsdcan @stefano Aww, I'll be waiting to view the resulting talk for BSDCan

And again @stefano outperformed me While I'm writing my home control system in #C for #NetBSD , he already preparing talk about his home control system for BSDCan

Thats the difference between North, with it's cold weather and low atmospheric pressure, and the South with humane environment

@h4890 On the PC — baresip (mostly for testing). Both phones are using Linphone (https://www.linphone.org/en/homepage-linphone/) application.

@vinishor I'm a newbie too, so I have a limited knowledge of these things. As I know, to connect old analog phones to the Asterisk you need some kind of telephony interface card in the server (e.g. some equipment from the Digium, mentioned in some comment here).

Just a moment...

In my case, these two phones are smartphones, so they have installed SIP-clients, which connects to the my Asterisk instance via the network, as any SIP-phone, like real phones used in offices.

@shapr

> you have done better than 90% of Digium customers in 2013

Lol, glad to hear that, thanks

@iquitsmoking Huh, I forgot to draw a legend (as usual, lol). The black arrows are for physical connections between devices and the blue arrows are for logical connections.

As I wrote before (https://mastodon.bsd.cafe/@evgandr/115912395421390028) I tried to use TURN server for communication with my relatives, but failed to setup secure enough solution. So, I decided to try an old and reliable solution — Asterisk. With the help of a book "Asterisk: The Definitive Guide" from J.V. Meggelen & R. Bryant & L. Madsen, of course.

First, I was forced to build the asterisk package by myself (from ports, ofc), since the binary version from NetBSD repository compiled with the all DB support, except my favourite PostgreSQL database.

By the way, adding users and writing dialplan with the help of aforementioned book was not so hard as I expected . Same for network setup. Since, I'm using PJSIP I just opened SIPS port and a range of UDP ports for RTP protocol on the my firewall. Despite, my home network hidden behind NAT on the router, there are no big problems with networking — end-user devices and an Asterisk server connected with use of simple star topology.

Surpisingly, the quality of the voice call is excellent comparing with service, provided by local cellular network operators. I suppose, that the secret in used codecs, or it is because there are not so much users (only 2) of my service.
