* Ekiga (Linux)

* Linphone 4.0.1 (Android)

* Twinkle (Linux) - although currently (Dec 2018) there's a problem with SRV records when using systemd-resolved (on Ubuntu and Debian at least)

* Twinkle (Linux) - although currently (Dec 2018) there's a problem with SRV records when using systemd-resolved (on Ubuntu and Debian at least). Need to do

systemctl stop systemd-resolved

⚫

* Voipfone Softphone (Android) deserves a mention. It needs an account with voipfone.co.uk, but you can signup and try for free. Their softphone app works out of the box for calling SIP URIs - provided they don't have ~~purely~~ numeric usernames: so you can call ~~an AAISP VoIP number (+44....) or~~ AAISP's office (e.g. support@aa.net.uk) but you can't call sip:<number>@host (it'll call the number direct instead).

systemctl disable systemd-resolved

systemctl mask systemd-resolved

add the line

dns=default

to the ''main'' section of ''/etc/NetworkManager/NetworkManager.conf''

and then

rm /etc/resolv.conf

to get NetworkManager to take over control of resolving.
