+# GNOME calls
+# - <https://gitlab.gnome.org/GNOME/calls>
+# - both a dialer and a call handler.
+# - uses callaudiod dbus package.
+#
+# initial JMP.chat configuration:
+# - message @cheogram.com "reset sip account"  (this is not destructive, despite the name)
+# - the bot will reply with auto-generated username/password plus a SIP server endpoint.
+#   just copy those into gnome-calls' GUI configurator
+# - now gnome-calls can do outbound calls. inbound calls requires more chatting with the help bot
+#
+# my setup here is still very WIP.
+# open questions:
+# - can i receive calls even with GUI closed?
+#   - e.g. activated by callaudiod?
+#   - looks like `gnome-calls --daemon` does that?
