  • It’s doable by hosting your own Asterisk or FreeSWITCH. You can accomplish this in FreeSWITCH using a GSM/LTE modem and the mod_gsmopen module. FreeSWITCH can also be used as an IMS provider for VoLTE, but that’s way too involved and probably not attainable for a home gamer. In Asterisk (or also an option for FreeSWITCH) I believe you will need an GSM to SIP Gateway which is going to be a bigger investment in terms of hardware as they tend to be rather specialized.

    I know you said you’d pefer the physical sim option so you can pay chash, which is valid. But also have a look at https://jmp.chat/ service, they are good people. They provide a SMS enabled gateway you can connect to with XMPP and specifically support multiple recipients.








  • Absolutely. Simply use ACME with the DNS validation method. Using bind you’ll want to create keys and allow TXT access for those keys to the validation domains. Fear not, this isn’t exclusive to bind, ACME tools supports dozens of other backends. That’s all you need the actual domain doesn’t need to be resolvable with an A/CNAME record. Internally you can run an entirely different DNS server to resolve your hosts, use hosts files, or use bind zones.


  • Except it isn’t. Saying it is trivial is just gross generalization. It’s trivial to configure bind to have internal zones that aren’t resolvable publically. It all depends on configuration, such as reverse ns entries, zone accessibility, etc.

    You can have (sub)domains that are listed in the certificate lists and yet aren’t resolvable externally as well.
