@jmjl@tilde.green Iâm sorry that Iâm not super knowledgeable about alternatives to jmp.chat but Iâll tell you what I know.
Youâre probably right about jmp.chat not working for you, at least as it is now. You can only get US and Canadian phone numbers through it last time I checked, so if youâre not in either of those countries youâd be making international calls all the time and people who wanted to call you would be making international calls too.
Iâve seen people talk about using SIP as an intermediary: you can bridge SIP-to-XMPP, and bridge SIP-to-PSTN (PSTN = âpacket switched telephone networkâ, meaning normal telephone). You can skip the SIP-to-XMPP side if youâre comfortable using a SIP client. I donât know very much about SIP or PSTN so I am not sure what to recommend, but perhaps this helps your search queries.
There are a fair number of services like TextNow that let you sign up for a real telephone number that you can then use via their app (I wouldnât use TextNowâthey had tons of spyware in their app). I donât know if that kind of service works for you but if it does perhaps youâd be able to find one of them that isnât horrible. This page (https://alternativeto.net/software/jmp-chat/) has a bunch of alternatives; I canât vouch for any of them but maybe itâs a starting point if you want to go this route.
Good luck!
