Thanks for the tip.
According to https://supportforums.cisco.com/t5/other-security-subjects/802-1x-authentication-not-happening-in-voice-domain-for-ip-phone/td-p/1652836
These need to be added
cisco-avpair="device-traffic-class=voice"
Tunnel-Type=1:VLAN
Tunnel-Medium-Type=1:802
Tunnel-Private-Group-ID=1:VOICE-LAN

So I added them as check attributes, with := but I got: 
Auth: (163) Invalid user (sql: Error parsing value: Unknown or invalid value "1:VLAN" for attribute Tunnel-Type): [ip phone name/<via Auth-Type = eap>] (from client Switch port 50145 cli mac)
Tue Jan 30 13:36:34 2018 : Auth: (163) Login incorrect (sql: Error parsing value: Unknown or invalid value "1:VLAN" for attribute Tunnel-Type): [ip phone name/<via Auth-Type = eap>] (from client Switch port 50145 cli mac)
If I delete the attribute
Tunnel-Type:=1:VLAN
(and it does not matter if I set it as a reply attribute, same error)
I get:
Auth: (159) Invalid user (sql: Error parsing value: Unknown or invalid value "1:802" for attribute Tunnel-Medium-Type): [ip phone name<via Auth-Type = eap>] (from client Switch port 50145 cli mac)
Tue Jan 30 13:34:30 2018 : Auth: (159) Login incorrect (sql: Error parsing value: Unknown or invalid value "1:802" for attribute Tunnel-Medium-Type): [ip phone name/<via Auth-Type = eap>] (from client Switch port 50145 cli mac)
The progress is that the ip phone now shows dropping packets on the voice vlan which means it accepted: 
Tunnel-Private-Group-ID:=1:VOICE-LAN 
After reading an email here: I'm inclined to replace ":=" with = but I have a limited lunch break to test these settings each day so perhaps someone who has dealt with this can save me some wasted time?
