interesting, voip dot ms now has their own branded softphone app for Android and iOS...

given the state of their API and the state of SIP calling on modern Android, I gotta be honest that I'm not super excited about this. I find my physical wifi-based VOIP phone way more user-friendly for phone calls, and thankfully 98% of my messaging happens in Signal so I don't have to deal with SIP texting much. there's a third-party app for that on #VoipMS but it's weird because their API is weird.
looks like #VoipMS still doesn't really handle group texts well at all in 2025. not great.
however, it's $1.10 a month for their metered lines, which is a big part of why I'm a customer ... that and the fact that I am one of the very few people who does nearly all their messaging on Signal
A little bit about some recent #VOIP adventures, featuring Hamshack Hotline, Hams over IP, NZSIP from DVNZ, and moving my ATT land line phone to voip.ms .
Please don't let anyone ever tell you that this is "not really ham radio" when there is a ham at each end of a conversation!
but thankfully there are parts of my #surfhosting tech stack which are fairly settled already:
OS: #LinuxMint; #Debian (with #LXQt if needed, or #BunsenLabs); #OpenWRT
Virtualization: #Proxmox
Hardware: refurb "1-liter" #1LPC business #miniPC from HP, Dell, Lenovo, with mid to high end CPU
Network: #GLiNet and #FriendlyElec #NanoPi routers / network-attached devices; #PiVPN
Phone: #VoipMS with dedicated SIP phone, plus softphone apps for limited use
Power: 90% of everything powered from compact #GaN USB-PD power supplies; 24/7 gear backed by ~15 year old consumer UPSes with drop-in LFP 12V batteries
For anyone using CHAN_SIP with #voipms, whatever unannounced migration/configuration change they just did (around ~12h ago) broke all those connections for inbound traffic (to your asterisk/freepbx boxes) only.
If you were affected by this, please comment and let me know.
despite the firmware bugs - which do seem to be getting fixed over time - having a physical VOIP phone like the Grandstream WP826 makes using a generic VOIP carrier like Voip dot ms so much less painful than software phones can be.
that's pretty important, especially when you realize that with #VoipMS you can have a phone like for about $2/month and $0.01/minute of talk time.
